OSPAR: A Corpus for Extraction of Organic Synthesis Procedures with Argument Roles.
Kojiro Machi, Seiji Akiyama, Yuuya Nagata, Masaharu Yoshioka
Journal of chemical information and modeling, 63, 21, 6619, 6628, 19 Oct. 2023, [Peer-reviewed], [Last author, Corresponding author], [International Magazine]
English, Scientific journal, There is a pressing need for the automated extraction of chemical reaction information because of the rapid growth of scientific documents. The previously reported works in the literature for the procedure extraction either (a) did not consider the semantic relations between the action and argument or (b) defined a detailed schema for the extraction. The former method was insufficient for reproducing the reaction, while the latter methods were too specific to their own schema and did not consider the general semantic relation between the verb and argument. In addition, they did not provide an annotated text that aligned with the structured procedure. Along these lines, in this work, we propose a corpus named organic synthesis procedures with argument roles (OSPAR) that is annotated with rolesets to consider the semantic relation between the verb and argument. We also provide rolesets for chemical reactions, especially for organic synthesis, which represent the argument roles of actions in the corpus. More specifically, we annotated 112 organic synthesis procedures in journal articles from Organic Syntheses and defined 19 new rolesets in addition to 29 rolesets from an existing language resource (Proposition Bank). After that, we constructed a simple deep learning system trained on OSPAR and discussed the usefulness of the corpus by comparing it with chemical description language (XDL) generated by a natural language processing tool, namely, SynthReader. While our system's output required more detailed parsing, it covered comparable information against XDL. Moreover, we confirmed that the validation of the output action sequence was easy as it was aligned with the original text.

Data-Augmentation Method for BERT-based Legal Textual Entailment Systems in COLIEE Statute Law Task
Yasuhiro Aoki, Masaharu Yoshioka, Youta Suzuki
REVIEW OF SOCIONETWORK STRATEGIES, 16, 175, 196, SPRINGER JAPAN KK, Feb. 2022, [Peer-reviewed], [Corresponding author]
English, Scientific journal, A legal textual entailment task is a task to recognize entailment between a law article and its statements. In the Competition on Legal Information Extraction/Entailment (COLIEE), this task is designed as a task to confirm the entailment of a yes/no answer from the given civil code article(s). Based on the development of deep-learning-based natural language processing tools such as bidirectional encoder representations from transformers (BERT), many participants in the task used such tools, and the best performance system of COLIEE 2020 was a BERT-based system. However, because of the limitation of the size of training data provided by the task organizer, training such tools to adapt to the variability of the questions is difficult. In this paper, we propose a data-augmentation method to make training data using civil code articles for understanding the syntactic structure of the questions and articles for entailment. Our BERT-based ensemble system, which uses this augmentation method, achieves the best performance (accuracy = 0.7037) in Task 4 of COLIEE 2021. We also introduce the results of additional experiments to discuss the characteristics of the proposed method.

English, Scientific journal, We summarize the 8th Competition on Legal Information Extraction and Entailment. In this edition, the competition included five tasks on case law and statute law. The case law component includes an information retrieval Task (Task 1), and the confirmation of an entailment relation between an existing case and an unseen case (Task 2). The statute law component includes an information retrieval Task (Task 3), an entailment/question answering task based on retrieved civil code statutes (Task 4) and an entailment/question answering task without retrieved civil code statutes (Task 5). Participation was open to any group based on any approach. Eight different teams participated in the case law competition tasks, most of them in more than one task. We received results from six teams for Task 1 (16 runs) and 6 teams for Task 2 (17 runs). On the statute law task, there were eight different teams participating, most in more than one task. Six teams submitted a total of 18 runs for Task 3, 6 teams submitted a total of 18 runs for Task 4, and 4 teams submitted a total of 12 runs for Task 5. Here we summarize the approaches, our official evaluation, and analysis on our data and submission results.

Diversity-robust acoustic feature signatures based on multiscale fractal dimension for similarity search of environmental sounds
Motohiro SUNOUCHI, Masaharu YOSHIOKA
IEICE Transactions on Information and Systems, E104D, 10, 1734, 1748, 2021, [Peer-reviewed], [Last author]
Scientific journal, This paper proposes new acoustic feature signatures based on the multiscale fractal dimension (MFD), which are robust against the diversity of environmental sounds, for the content-based similarity search. The diversity of sound sources and acoustic compositions is a typical feature of environmental sounds. Several acoustic features have been proposed for environmental sounds. Among them is the widely-used Mel-Frequency Cepstral Coefficients (MFCCs), which describes frequency-domain features. However, in addition to these features in the frequency domain, environmental sounds have other important features in the time domain with various time scales. In our previous paper, we proposed enhanced multiscale fractal dimension signature (EMFD) for environmental sounds. This paper extends EMFD by using the kernel density estimation method, which results in better performance of the similarity search tasks. Furthermore, it newly proposes another acoustic feature signature based on MFD, namely very-long-range multiscale fractal dimension signature (MFD-VL). The MFD-VL signature describes several features of the time-varying envelope for long periods of time. The MFD-VL signature has stability and robustness against background noise and small fluctuations in the parameters of sound sources, which are produced in field recordings. We discuss the effectiveness of these signatures in the similarity sound search by comparing with acoustic features proposed in the DCASE 2018 challenges. Due to the unique descriptiveness of our proposed signatures, we confirmed the signatures are effective when they are used with other acoustic features.

BERT-based ensemble methods with data augmentation for legal textual entailment in COLIEE statute law task.

Proceedings of the 18th International Conference on Artificial Intelligence and Law, ICAIL 2021, 278, 284, ACM, 2021, [Peer-reviewed], [Lead author]
International conference proceedings, The Competition on Legal Information Extraction/Entailment (COLIEE) statute law legal textual entailment task (task 4) is a task to make a system judge whether a given question statement is true or not by provided articles. In the last COLIEE 2020, the best performance system used bidirectional encoder representations from transformers (BERT), a deep-learning-based natural language processing tool for handling word semantics by considering their context. However, there are problems related to the small amount of training data and the variability of the questions. In this paper, we propose a BERT-based ensemble method with data augmentation to solve this problem. For the data augmentation, we propose a systematic method to make training data for understanding the syntactic structure of the questions and articles for entailment. In addition, due to the nature of the non-deterministic characteristics of BERT fine-tuning and the variability of the questions, we propose a method to construct multiple BERT fine-tuning models and select an appropriate set of models for ensemble. The accuracy of our proposed method for task 4 was 0.7037, which was the best performance among all submissions.

English, International conference proceedings, This paper describes our system for the ChEMU 2021 task 2 of anaphora resolution for extracting chemical reactions from patents. We divide the task into two subtasks: (1) span detection of mentions that include antecedent and anaphor; and (2) mention classification and relation detection. For the first task, we use a deep learning-based approach. For the second task, we use a rule-based approach that uses features related to chemical reactions by ChemicalTagger, which is a state-of-the-art text-mining tool for chemistry. Our system obtained an exact-match F-score of 0.6907 and a relaxed match F-score of 0.7459.

CEUR Workshop Proceedings, 2721, 300, 305, CEUR-WS.org, 2020, [Peer-reviewed], [Lead author]
English, International conference proceedings, Wikipedia categories are intended to group together pages on similar topics and are organized in a hierarchical structure. Since the editorial policy for Wikipedia categories differs from policies used by knowledge engineers, various types of relationship exist in its category structure. In this paper, we propose a novel framework called "Wikipedia category ontology" (WCO) that aims to act as a basis for interpreting the Wikipedia category structure and is based on a classification of category and relationship types. WCO enables particular Wikipedia category substructures to be extracted, including class-subclass hierarchies, class-instance, and sets of diffused categories for a particular category. WCO is available online in the form of linked open data at http://wcontology.org/.

English, International conference proceedings, Several general-purpose databases of research papers are available, including ScienceDirect and Google Scholar. However, these systems may not include recent papers from workshops or conferences for special interest groups. Moreover, it can be helpful for researchers in a particular domain to analyze research papers using their own terminology. To support these researchers, we propose a new database system based on the information extracted from portable document format documents that enables annotation of terms via a terminology extraction system. In this paper, we evaluate our system using a use-case experiment and discuss the appropriateness of the system.

International conference proceedings, We develop a novel framework that helps identify potential bias in news websites to support users who are exposed to news articles with a wide variety of political leanings. We propose a polarity-based stance (PS), a vector that represents how often a website publishes articles that are positive or negative with regard to a topic. We derive PS using the GDELT database and visualize the news websites' stances. We demonstrate the utility of our framework via a case study of the 2016 US Presidential Election.

English, International conference proceedings, Search engine is an important tool of modern academic study, but the results are lack of measurement of beginner friendliness. In order to improve the efficiency of using search engine for academic study, it is necessary to invent a technique of measuring the beginner friendliness of a Web page explaining academic concepts and to build an automatic measurement system. This paper studies how to integrate heterogeneous features such as a neural image feature generated from the image of the Web page by a variant of CNN (convolutional neural network) as well as text features extracted from the body text of the HTML file of the Web page. Integration is performed through the framework of the SVM classifier learning. Evaluation results show that heterogeneous features perform better than each individual type of features.

English, International conference proceedings, Data visualization is a core approach for understanding data specifics and extracting useful information in a simple and intuitive way. Visual data mining proceeds by projecting multidimensional data onto two-dimensional (2D) or three-dimensional (3D) data, e.g., through mathematical optimization and topology preserved in multidimensional scaling (MDS). However, this projection does not necessarily comply with the user's needs, prior knowledge and/or expectations. This paper proposes an interactive visual mining approach, centered on the user's needs and allowing the modification of data visualization by leveraging approaches from metric learning. The paper exemplifies the proposed system, referred to as Interactive Metric Learning-based Visual Data Exploration (IMViDE), applied to scientific social network browsing.

We also present examples of analyses performed using this system.

NaDev: An annotated corpus to support information extraction from research papers on nanocrystal devices

English, Scientific journal, The process of nanocrystal device development is not well systematized. To support this process, analysis of the information produced by developmental experiments is required. In this study, we constructed an annotated corpus to support the extraction of experimental information from relevant publications. We designed the corpus-construction guidelines by cooperating with a domain expert. We evaluated these guidelines through corpusconstruction experiments with graduate students from this domain, and then evaluated the corpus with the domain expert. In the corpus construction experiments, we achieved a sufficient level of Inter-Annotator Agreement by using a loose agreement measure that ignored the term-boundary mismatch problem, and made an agreement corpus that excluded annotations based on misunderstanding the guidelines. The domain expert evaluated this agreement corpus and modified the guidelines based on real examples. Using these guidelines, we finalized the corpus called "NaDev" (Nanocrystal Device development corpus). The NaDev corpus and its construction guidelines will be released via our website, http://nanoinfo.ist.hokudai.ac.jp/. The NaDev corpus aims to support automatic information extraction from publications relevant to nanocrystal device development. This information can be used to solve problems in the nanotechnology domain using the massive availability of fresh information. To the best of our knowledge, this is the first corpus constructed for the development of nanocrystal devices.

Framework for automatic information extraction from research papers on nanocrystal devices

English, Scientific journal, To support nanocrystal device development, we have been working on a computational framework to utilize information in research papers on nanocrystal devices. We developed an annotated corpus called "NaDev" (Nanocrystal Device Development) for this purpose. We also proposed an automatic information extraction system called "NaDevEx" (Nanocrystal Device Automatic Information Extraction Framework). NaDevEx aims at extracting information from research papers on nanocrystal devices using the NaDev corpus and machine-learning techniques. However, the characteristics of NaDevEx were not examined in detail. In this paper, we conduct system evaluation experiments for NaDevEx using the NaDev corpus. We discuss three main issues: system performance, compared with human annotators; the effect of paper type (synthesis or characterization) on system performance; and the effects of domain knowledge features (e.g., a chemical named entity recognition system and list of names of physical quantities) on system performance. We found that overall system performance was 89% in precision and 69% in recall. If we consider identification of terms that intersect with correct terms for the same information category as the correct identification, i.e., loose agreement (in many cases, we can find that appropriate head nouns such as temperature or pressure loosely match between two terms), the overall performance is 95% in precision and 74% in recall. The system performance is almost comparable with results of human annotators for information categories with rich domain knowledge information (source material). However, for other information categories, given the relatively large number of terms that exist only in one paper, recall of individual information categories is not high (39-73%); however, precision is better (75-97%). The average performance for synthesis papers is better than that for characterization papers because of the lack of training examples for characterization papers. Based on these results, we discuss future research plans for improving the performance of the system.

2015 11TH INTERNATIONAL CONFERENCE ON SIGNAL-IMAGE TECHNOLOGY & INTERNET-BASED SYSTEMS (SITIS), 712, 718, IEEE, 2015, [Peer-reviewed], [Lead author]
English, International conference proceedings, Wikipedia is a free Internet encyclopedia that covers numerous topics and is maintained by voluntary editors. There have been several efforts to analyze the quality of Wikipedia's content, specifically assessing textual content and user editorial behavior. However, there has been no specific analysis of the quality of structured data (e.g., category structures, attributes contained in infoboxes) in Wikipedia. DBPedia is one of a core part of Linked Open Data database which extracts structured information from Wikipedia. Since the quality of DBPedia depends on Wikipedia, it is beneficial to have a mechanism to keep a consistent style of writing of the structured data (metadata) within Wikipedia. In this paper, we propose a system WC3 (WC-triple: Wikipedia Category Consistency Checker) that uses DBPedia RDF-triple information to evaluate the consistency of the metadata related to the Wikipedia category information. We also illustrate examples of typical inconsistencies that the system can assist in detecting.

English, Scientific journal, The automatic extraction of chemical information from text requires the recognition of chemical entity mentions as one of its key steps. When developing supervised named entity recognition (NER) systems, the availability of a large, manually annotated text corpus is desirable. Furthermore, large corpora permit the robust evaluation and comparison of different approaches that detect chemicals in documents. We present the CHEMDNER corpus, a collection of 10,000 PubMed abstracts that contain a total of 84,355 chemical entity mentions labeled manually by expert chemistry literature curators, following annotation guidelines specifically defined for this task. The abstracts of the CHEMDNER corpus were selected to be representative for all major chemical disciplines. Each of the chemical entity mentions was manually labeled according to its structure-associated chemical entity mention (SACEM) class: abbreviation, family, formula, identifier, multiple, systematic and trivial. The difficulty and consistency of tagging chemicals in text was measured using an agreement study between annotators, obtaining a percentage agreement of 91. For a subset of the CHEMDNER corpus (the test set of 3,000 abstracts) we provide not only the Gold Standard manual annotations, but also mentions automatically detected by the 26 teams that participated in the BioCreative IV CHEMDNER chemical mention recognition task. In addition, we release the CHEMDNER silver standard corpus of automatically extracted mentions from 17,000 randomly selected PubMed abstracts. A version of the CHEMDNER corpus in the BioC format has been generated as well. We propose a standard for required minimum information about entity annotations for the construction of domain specific corpora on chemical and drug entities. The CHEMDNER corpus and annotation guidelines are available at: http://www.biocreative.org/resources/biocreative-iv/chemdner-corpus/

Analysis of Japanese Wikipedia Category for Constructing Wikipedia Ontology and Semantic Similarity Measure
Masaharu Yoshioka
INFORMATION RETRIEVAL TECHNOLOGY, AIRS 2014, 8870, 470, 481, SPRINGER-VERLAG BERLIN, 2014, [Peer-reviewed], [Lead author]
English, International conference proceedings, Wikipedia is a free encyclopedia on the Internet that contains millions of articles. Wikipedia ontologies (e.g., YAGO2 and the Japanese Wikipedia ontology) have been constructed to utilize the semantic information in this encyclopedia; in these ontologies, the category information from each article is used to construct concept hierarchies. However, Wikipedia categories were originally designed for navigation, to help users find appropriate articles, and they are not equivalent to concept hierarchies in Wikipedia ontologies. In this study, we briefly review the definition of a category in Wikipedia and exhaustively investigate the category structure in the Japanese Wikipedia. We also discuss how category structure information can be utilized to construct an ontology and to calculate a semantic similarity measure.

Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), 7774, 375, 381, Springer, 2013, [Peer-reviewed]
English, International conference proceedings, It is now possible to use various geographical open data sources such as GeoNames and Wikipedia to construct geographic information systems. In addition, these open data sources are integrated by the concept of Linked Open Data. There have been several attempts to identify links between existing data, but few studies have focused on the quality of such links. In this paper, we introduce an automatic link discovery method for identifying the correspondences between GeoNames entries and Wikipedia pages, based on Wikipedia category information. This method finds not only appropriate links but also inconsistencies between two databases. Based on this integration results, we discuss the type of inconsistencies for making consistent Linked Open Data. © Springer-Verlag 2013.

In this paper, we introduce a Japanese gazetteers based on Open Data (e.g., the Toponym database distributed by Japanese ministries, Wikipedia, and GeoNames) and propose a toponym disambiguation framework that uses the constructed gazetteers. We also evaluate our approach based on a blog corpus that contains place names with high ambiguity.

Applying a burst model to detect bursty topics in a topic model
Yusuke Takahashi, Takehito Utsuro, Masaharu Yoshioka, Noriko Kando, Tomohiro Fukuhara, Hiroshi Nakagawa, Yoji Kiyota
Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), 7614, 239, 249, Springer, 2012, [Peer-reviewed]
English, International conference proceedings, This paper focuses on two types of modeling of information flow in news stream, namely, burst analysis and topic modeling. First, when one wants to detect a kind of topics that are paid much more attention than usual, it is usually necessary for him/her to carefully watch every article in news stream at every moment. In such a situation, it is well known in the field of time series analysis that Kleinberg's modeling of bursts is quite effective in detecting burst of keywords. Second, topic models such as LDA (latent Dirichlet allocation) are also quite effective in estimating distribution of topics over a document collection such as articles in news stream. However, Kleinberg's modeling of bursts is usually applied only to bursts of keywords but not to those of topics. Considering this fact, we propose how to apply Kleinberg's modeling of bursts to topics estimated by a topic model such as LDA and DTM (dynamic topic model). © 2012 Springer-Verlag Berlin Heidelberg.

some of this knowledge is tacit, based on the user's experience. Therefore, it is difficult to become a good engineer in this development process. We propose the concept of "Evidence-based experiment planning" and develop a process for supporting experiment planning in nanodevice development. This system applies knowledge discovery techniques to records of previous experiments to extract experienced engineers' tacit knowledge. Copyright 2010 ACM.

English, International conference proceedings, Among other domains and topics on which some issues are frequently argued in the blogosphere, the domain of crime is one of the most seriously discussed by various kinds of bloggers. Such information on crimes in blogs is especially valuable for those who are not familiar with tips for preventing being victimized. This paper proposes a framework of extracting people's concerns and reports on crimes in their own blogs. In this framework, we solve two tasks. In the first task, we focus on experts in crime domain and address the issue of extracting concerns on crimes such as tips for preventing being victimized. In the evaluation of this first task, we show that we successfully rank expert bloggers high in the results of blog feed retrieval. In the second task, on the other hand, we focus on victims of criminal acts, and address the issue of extracting reports on being victimized In the evaluation of this second task, we show that we outperform blog post ranking based on the search engine API by incorporating dependency relations for identifying victims' blog posts.

SITIS 2008: 4TH INTERNATIONAL CONFERENCE ON SIGNAL IMAGE TECHNOLOGY AND INTERNET BASED SYSTEMS, PROCEEDINGS, 45, 51, IEEE COMPUTER SOC, 2008, [Peer-reviewed]
English, International conference proceedings, Today, there is access to large numbers of news sites in different countries, and there are several experimental systems, such as Newsblaster and NewsExplorer that integrate news articles about a particular event from multiple news sites. These systems enable a good understanding of particular events by using multiple news sites, but they ignore the characteristics of the various news sites. To characterize the differences between news sites, the News Site Contrast (NSContrast) system has been proposed. This system analyzes multiple news sites using the concept of contrast-set mining. However NSContrast has only limited analysis functions and is not mature enough for evaluation via user experiments. Therefore, in this paper, we analyze contrast set mining results for NSContrast, aiming to understand the requirements for extracting useful information that also reflects the interests of different countries. Based on this analysis, a new NSContrast is introduced and applied to a news article database constructed from multiple news sites in different countries for user experimentation.

English, Scientific journal, Query term expansion is an important technique for achieving higher retrieval performance. However, since many factors affects the quality of this technique, it is difficult to evaluate this technique in isolation. Feature quantities that characterize the quality of the initial query are defined in this study for evaluating topic difficulties from the viewpoint of query term expansion. I also briefly review the result of the NTCIR-5 query term expansion subtask that uses these quantities for evaluating the effectiveness of the query term expansion techniques. I also describe detailed analysis results on the effect of query term expansion based on topic-by-topic analysis.

Fundamental Plot for a Designer Support Environment based on Abduction

Japanese, This paper describes a new design support system that supports conceptual or creative design by dynamically integrating knowledge in different design domains. We argue that abduction for integrating theories can be a basic principle to formalize such design processes. Based on this principle, we propose Universal Abduction Studio, a design environment in which designers combine different theories to arrive at better design. In this new approach to computational support of conceptual design, the system should offer various types of abductive reasoning from which designers can select an interesting design method. We also discuss technologies to implement UAS and in this paper we propose to use analogical reasoning as abductive reasoning to discover relationships between knowledge from different sources. We demonstrate that a prototype system can discover a new idea in a design example taken from a real design activity.

Research on Information Retrieval System that Supports Keyword Selection based on Generalized Concept and Coverage
YOSHIOKA Masaharu, HARAGUCHI Makoto
Transactions of the Japanese Society for Artificial Intelligence, 20, 4, 270, 280, The Japanese Society for Artificial Intelligence, 01 Nov. 2005
Japanese, It is not easy for a user of an Information Retrieval (IR) system to select an appropriate keyword set to represent his or her specific information need. Therefore, many IR systems can modify keyword sets by estimating the user's particular requirement. Even though such IR systems have better retrieval performance, the complicated estimation process entailed by a large number of keywords makes it difficult for a user to understand how the system behaves. Therefore, we used a thesaurus for query expansion. To select an appropriate keyword set, we proposed two concepts: ``adaptive generalization'', which estimates an appropriate generalization level of the given keywords by using relevant document information, and ``purpose-oriented concept structure modification'', which selects relevant keywords from a predefined synonym set in a thesaurus. Because query expansion based on a thesaurus aims to find new keywords that are complementary to the initial keywords, we proposed to use this method to construct a Boolean query formula to represent the user's information need. We proposed a new IR system called ``appropriate Boolean query reformulation for IR with adaptive generalization'' (ABRIR-AG) to support Boolean query formation. In ABRIR-AG, we reformulated a user-given Boolean query by using a small number of relevant documents.

An appropriate Boolean query reformulation interface for information retrieval based on adaptive generalization
M Yoshioka, M Haraguchi
International Workshop on Challenges in Web Information Retrieval and Integration, Proceedings, 145, 150, IEEE COMPUTER SOC, 2005, [Peer-reviewed]
English, International conference proceedings, When implementing an IR system that can support comprehensive searches from a wide variety of documents, it is crucial to have a mechanism for selecting appropriate query formulations. For this purpose, many IR systems can modify query terms by estimating the user's information need. However because modified query terms are usually represented in a complicated form, it is difficult to judge how appropriate they are. In this research, we assume all relevant documents should contain words that correspond to concepts that the user would like to retrieve. Therefore, a Boolean query formula is one good way to represent a user's information need with high readability. To find the required concepts in a relevant document set, we have previously proposed a new IR system that calculates appropriate generalized concepts to represent the user's need. In this study, we implement a user interface that supports reformulation of IR queries by using abstract concepts.

On a combination of probabilistic and Boolean IR models for WWW document retrieval
Masaharu Yoshioka, Makoto Haraguchi
ACM Transactions on Asian Language Information Processing, 4, 3, 340, 356, 2005, [Peer-reviewed]
English, International conference proceedings, Even though a Boolean query can express the information need precisely enough to select relevant documents, it is not easy to construct an appropriate Boolean query that covers all relevant documents. To utilize a Boolean query effectively, a mechanism to retrieve as many as possible relevant documents is therefore required. In accordance with this requirement, we propose a method for modifying a given Boolean query by using information from a relevant document set. The retrieval results, however, may deteriorate if some important query terms are removed by this reformulation. A further mechanism is thus required in order to use other query terms that are useful for finding more relevant documents, but are not strictly required in relevant documents. To meet this requirement, we propose a new method that combines the probabilistic IR and the Boolean IR models. We also introduce a new IR system - called appropriate Boolean query reformulation for information retrieval (ABRIR) - based on these two methods and the Okapi system. ABRIR uses both a word index and a phrase index formed from combinations of two adjacent noun words. The effectiveness of these two methods was confirmed according to the NTCIR-4 Web test collection. © 2005 ACM.

Towards construction of evaluation framework for query expansion

INFORMATION RETRIEVAL TECHNOLOGY, PROCEEDINGS, 3689, 647, 652, SPRINGER-VERLAG BERLIN, 2005, [Peer-reviewed]
English, Scientific journal, Query expansion is an important technique for achieving higher retrieval performance. However, a good framework for evaluating this technique in isolation does not, exist because the effect of query expansion depends on the quality of the initial query. Feature quantities that characterize the quality of the initial query are defined in this study. Correlations between these quantities and retrieval performance were analyzed using the NTCIR-4 web test collection.

Physical concept ontology for the knowledge intensive engineering framework

ADVANCED ENGINEERING INFORMATICS, 18, 2, 95, 113, ELSEVIER SCI LTD, Apr. 2004, [Peer-reviewed]
English, Scientific journal, Knowledge intensive engineering aims at flexible applications of a variety of product life cycle knowledge. much as design, manufacturing. operations, maintenance, and recycling. Many engineering domain theories are organized and embedded within CAD and CAE tools and engineering activities can be formalized as modeling operations to them. Since most of domain theories deal with the physical world and can be associated with physical concepts. a physical concept ontology can form a common ontology to integrate engineering models that are formed based on domain theories. This paper reports a physical ontology-based support system for knowledge intensive engineering called Knowledge intensive Engineering Framework (KIEF) to integrate multiple engineering models and to allow more flexible use of them. First the paper describes the physical ontology as the core of KIEF and an ontology-based reasoning system called a pluggable metamodel mechanism, to integrate and maintain relationships among these models. The pluggable metamodel mechanism uses a metamodel that represents the designer's mental model about a design object as a concept network model. The designer builds and decomposes a functional hierarchy from functional specifications with an FBS (Function-Behavior-State) modeler. He/She then maps the functional hierarchy into a metamodel using physical features that are building blocks for conceptual design. Then, the pluggable metamodel mechanism enriches the information contained in the metamodel by using causal dependency knowledge about the physical world and by budding and analzing various engineering models. We demonstrate the power of KIEF by illustrating a design case performed on KIEF. (C) 2004 Published by Elsevier Ltd.

A methodology for IR query clarification based on adaptive generalization
M Yoshioka, M Haraguchi
8TH WORLD MULTI-CONFERENCE ON SYSTEMICS, CYBERNETICS AND INFORMATICS, VOL I, PROCEEDINGS, I, 226, 230, INT INST INFORMATICS & SYSTEMICS, 2004
English, International conference proceedings, We can use various types of information retrieval (IR) system to access large quantities of text data. These systems usually request users to input keywords to represent their retrieval intention. Since, it is difficult for a user to select appropriate keywords, many IR systems have the capability of modifying keywords by estimating the user's intention. However because modified keywords are usually represented in a complicated form, it is difficult to judge how appropriate they are. In this research, we assume all relevant documents should have words that correspond to concepts that the user would like to retrieve. Therefore, a boolean query formula is one good way to represent user's intent with higher readability. In order to find out these concepts in a relevant document set, we have already proposed a new IR system that calculates appropriate generalized concept to represent user's intention. In this study, we implement a user interface that supports to clarify IR query by using abstract concepts.

Towards constructing story databases using maximal analogies between stories

INTUITIVE HUMAN INTERFACES FOR ORGANIZING AND ACCESSING INTELLECTUAL ASSETS, 3359, 243, 255, SPRINGER-VERLAG BERLIN, 2004, [Peer-reviewed]
English, Scientific journal, In order to construct story databases, it is crucial to have an effective index that represents the plot and event sequences in a document. For this purpose, we have already proposed a method using the concept of maximal analogy to represent a generalized event sequence of documents with a maximal set of events. However, it is expensive to calculate a maximal analogy from documents with a large number of sentences. Therefore, in this paper, we propose an efficient algorithm to generate a maximal analogy, based on graph theory, and we confirm its effectiveness experimentally. We also discuss how to use a maximal analogy as an index for a story database, and outline our future plans.

English, International conference proceedings, To classify a document set from various viewpoints, we extract a possible abstract document from given similar documents. The abstract one is a common generalization of the original documents. Although we can present an efficient algorithm to find it under some pruning rule, it is generally very hard to perform such a task of extracting abstract documents. It is therefore necessary to reduce the numbers of events appearing in documents. For this purpose, we regard one document as a network of events, present a pseudo-PageRank model for calculating the importance of events, analyze and compare it with a standard text summarization method, and finally reports the present approach to improve the pseudo-PageRank.

Knowledge Management System for Problem Solving: Integration of Document Information and Formalized Knowledge

Volume 1: 23rd Computers and Information in Engineering Conference, Parts A and B, ASMEDC, 01 Jan. 2003, [Peer-reviewed], [Lead author]
International conference proceedings, In engineering activities various types of problems have to be solved. Most of these problems are routine problems and some are complicated problems for which it is difficult to formalize all the problem-solving processes. We propose a knowledge management system for supporting these problem solving processes. One example is using information applicable to new and complicated problems that has resulted from solving similar problems in the past. In addition, in such complicated problem solving processes, most of the decomposed sub-problems can be handled as routine problems. In this paper, we propose use of formalized knowledge and document information that represents the history of problem-solving processes to support the solution of both types of problem. For that purpose, we propose the Documentation Management system for Problem Solving (DMaPS), which supports a user solving a problem by document processing. In this support process, the system retrieves related documents for the user’s problems using formalized knowledge and information retrieval techniques. After retrieving related documents, the user modifies them to fit their problem. The modified information is associated with the formalized knowledge and is stored as documents for future reuse.

Proceedings of the ASME Design Engineering Technical Conference, 3, 543, 552, 2003, [Peer-reviewed]
International conference proceedings, While abduction is considered crucial for design in general, this paper focuses on the role of abduction to integrate knowledge assuming that creative design can come from innovative combination of existing knowledge. Based on Schurz's classification of abductive reasoning, the paper identifies that abduction for integrating theories can be performed by a special type of abduction called second order existential abduction. The paper then analyzes refrigerator design cases to understand how knowledge is used and shows that abduction is indeed central to design. It also discusses that knowledge structure is a key concept in abduction for integration.

Analysis of Japanese Deverbal Compounds Based on Lexical Conceptual Structure

Transactions of Information Processing Society of Japan, 43, 5, 1446, 1456, Information Processing Society of Japan (IPSJ), 15 May 2002
Japanese, In this paper, we describe a principled approach for analyzing relations between constituent words of compound nouns, specifically those whose heads are deverbal nouns, based on the classification of deverbal nouns by their lexical conceptual structure (LCS) and the classification of nouns in modifier position vis-a-vis LGS of head deverbal nouns. There are two kinds of relations of compounds with head deverbal nouns. The one is that a modifier noun becomes an argument of deverbal head and the other is that a modifier becomes an adjunct. It is an important starting point for analyzing relations to disambiguate the two kinds of relations. Through the qualitative analysis of the data and the experimental evaluation of 1231 compound nouns, we show that the use of LCS as the theoretical basis is very promising for constructing compound analyzer.

Construction of a Large Scale Test Collection NTCIR-2 : The Effect of Additional Interactive Search and Cross-Lingual Pooling
KURIYAMA KAZUKO, YOSHIOKA MASAHARU, KANDO NORIKO
情報処理学会論文誌データベース（TOD）, 43, 2, 48, 59, Information Processing Society of Japan (IPSJ), 15 Mar. 2002
Japanese, The purposes of this study are to examine whether there is an effect on the relative evaluation of the IR systems using the relevance judgments of the test collection NTCIR-2 made by the pooling method and additional interactive searches, and to investigate whether the NTCIR-2 is effective for evaluating the IR systems, the search results of which were not used for the pooling. We carried out experiments using different lists of relevance judgments and search results submitted for the test of the 2nd NTCIR Workshop. First, we evaluated the search results using the list of the final relevance judgments F of NTCIR-2 and F - I, that is, the F without the unique relevant documents found by the additional interactive searches I. Second, we made pools from the search results for each of the sub-tasks and evaluated the search results using the pools as lists of relevance judgments. Third, we evaluated the search results using F - S, that is, the F without the unique relevant documents found by an IR system S in order to simulate evaluation of the IR system which was not used for the pooling. Almost the same rankings of the search results were produced by using the pools as lists of relevance judgments for system evaluation. When the search results by an JR system were not used for the pooling, there is a very little effect on evaluation of the system itself and relative evaluation among it and other systems. Therefore our results verified the reliability of test collection as an evaluation tool, which was based on pooling method.

2001 IEEE INTERNATIONAL CONFERENCE ON SYSTEMS, MAN, AND CYBERNETICS, VOLS 1-5, 904, 909, IEEE, 2002, [Peer-reviewed]
English, International conference proceedings, This paper proposes a method to describe conceptual meanings of Japanese deverbal nouns for the purpose of analysing Japanese compound nouns. A lexical meaning of each constituent word is very important since it deeply influences a word formation of compound words. Therefore we intend to use the lexical meanings of constituent words to build a Japanese compound noun analyser. As a first step to describe lexical meanings of words, we have established a simple semantic structure based on lexical conceptual structure (we refer to the structure we establish by TLCS1 in this paper). After the analysing 250 deverbal nouns that appeared in technical terms, we found that the only 14 types of TLCSes cover various deverbal nouns. We will explain in this paper the types of TLCS and also show the procedure of assigning TLCSes to deverbals. In order to evaluate the efficacy of TLCS, we made use of the accuracy of simple compound noun analyser for analysing technical terms. The result was very good, which shows that our proposed method is very promising.

A proposal of CAD mechanism for design knowledge management

Transactions of the Japanese Society for Artificial Intelligence, 17, 1, 104, 113, 2002

This mechanism encourages a designer to externalise his/her knowledge during a design process and facilitates sharing and reuse of such externalised design knowledge in later stages. We also describe the implementation of this idea called DDMS (Design Documentation Management System). DDMS works as a front end to KIEF (Knowledge Intensive Engineering Framework), which we have been developing. We also illustrate an example of machining tool design to demonstrate the features of DDMS.

Discovery of maximal analogies between stories
M Haraguchi, S Nakano, M Yoshioka
DISCOVERY SCIENCE, PROCEEDINGS, 2534, 324, 331, SPRINGER-VERLAG BERLIN, 2002
English, Scientific journal, Given two documents in the form of texts, we present a notion of maximal analogy representing a generalized event sequence of documents with a maximal set of events. They are intended to be used as extended indices of documents to automatically organize a document database from various viewpoints. The maximal analogy is defined so as to satisfy a certain consistency condition and a cost condition. Under the consistency condition, a term in an event sequence is generalized to more abstract term independently of its occurrence positions. The cost condition is introduced so that meaningless similarities between documents are never concluded. As the cost function is monotone, we can present an optimized bottom-up search procedure to discover a maximal analogy under an upper bound of cost. We also show some experimental results based on which we discuss a future plan.

International conference proceedings,
We propose a new integrated computational environment, called a Knowledge Intensive Engineering Framework (KIEF), to support design object modeling, during engineering design process that requires a variety of design object models, such as a geometric model, a control model, and a finite element model. KIEF is capable of guiding designers with design process knowledge based on a model of synthesis, of integrating multiple design object models, and of maintaining consistency among these models. The design process knowledge is a result of a research project we conduct to establish a model of synthesis. This model formalizes design process knowledge in a design process as operations to a multiple model-based reasoning system, such as KIEF, and from a language of synthesis. We describe a prototype system that incorporates design process knowledge to KIEF and illustrate an example design on it.

A Theory of Design Object Knowledge Operations

Journal of the Japan Society for Precision Engineering, 67, 9, 1490, 1496, The Japan Society for Precision Engineering, 05 Sep. 2001
Japanese, In a design process, a designer uses various kinds of design object knowledge, such as physical laws, mechanism library, and manufacturing knowledge. Therefore, it is necessary for a CAD system to handle large scale knowledge bases to support this process. However, it is difficult to use a large scale knowledge base without knowledge about operations of the knowledge itself. This paper proposes a theory of design knowledge operations. First, we analyze the results of design experiments that are records of real design processes. Second, we formalize design knowledge operations based on General Design Theory. Finally we discuss the generality of the proposed formalism of design knowledge operations.

In order to solve this problem, this paper proposes a design methodology for upgradable products, Especially, this paper discusses a method dealing with uncertainty caused by long-term planning in the design methodology for upgradability Namely, the proposed method deals with uncertainty as ranges of parameter values, and derives a design solution that realizes required upgrades, while adapting to estimated uncertainty. This method makes the products robust and tolerant against the uncertainty and, therefore, makes design for upgradability more feasible.

Japanese, During design, a designer uses various computational tools, such as a geometric modeling system, analysis tools, and databases. To support these design processes, a system that can integrate such computational tools is required. For this purpose, we have been developing the Knowledge Intensive Engineering Framework (KIEF) system. KIEF enables the designer to build, evaluate, and modify design models on the system by providing him/her with a wide variety of engineering knowledge. A common ontology plays an important role in integrating tools and representing engineering knowledge. This paper describes the structure of the ontology in KIEF, and how it is used in a modeling processes on KIEF.

A proposal of design methodology for upgradable products
Yasushi Umeda, Yoshiki Shimomura, Masaharu Yoshioka, Tetsuo Tomiyama
Proceedings of the ASME Design Engineering Technical Conference, 4, 407, 417, American Society of Mechanical Engineers (ASME), 1999
English, International conference proceedings, One of main causes of the environmental issues is the current mass production paradigm. Developing upgradable products is one of the most hopeful approaches for solving these issues, because they will have longer lives, encourage reuse of artifacts, and therefore, create new business chances at later stage.s of product life cycles. However, design for upgradability has been hardly discussed. Thi.s paper proposes a design methodology for upgradable products. First, we clarify the definition of design for upgradability by comparing it with other design strategies. Second, by analyzing data of existing serie.s design, we propose several design pattem.s and two basic guiding principles
namely, making function independent and making function insensitive. Based on these analyses, a design methodology for upgradability is proposed and a prototype of upgrade design support system i.s illustrated. Finally, feasibility of the methodology i.s discussed by applying result of an experimental design to the prototype system.

Toward a reasoning framework of design as synthesis
Masaharu Yoshioka, Tetsuo Tomiyama
Proceedings of the ASME Design Engineering Technical Conference, 3, 1, 11, American Society of Mechanical Engineers (ASME), 1999
English, International conference proceedings, Most of the previous research efforts for design process modeling had such assumptions as "design as problem solving,""design as decision making,"and "design by analysis,"and did not explicitly address "design as synthesis."These views lack notion and understanding about synthesis. Compared with analysis, synthesis is less understood and clarified. This paper discusses our fundamental view on synthesis and approach toward a reasoning framework of design as synthesis. To do so, we observe the designer's activity and formalize knowledge operations in design processes. From the observation, we propose a hypothetical reasoning framework of design based on multiple model-based reasoning. We discuss the implementation strategy for the framework.

A Study on an Integrated Modeling Environment for Design: A Proposal of the Pluggable Metamodel Mechanism
YOSHIOKA Masaharu, TOMIYAMA Tetsuo, Masaharu Yoshioka, Tetsuo Tomiyama
Journal of Japanese Society for Artificial Intelligence, 13, 2, 312, 319, The Japanese Society for Artificial Intelligence, 01 Mar. 1998
Japanese, In this study, we propose a framework of an integrated modeling environment for design. Since a mechanical engineering design process requires various kinds of design object models, such as a geometric model, a kinematic model, and a finite element model, this environment should maintain consistency among these models. Furthermore, commercial design tools are practically used in design processes, and these must be integrated as well. For dealing with multiple design object models, we have formalized a concept called a metamodel. A metamodel is a model which represents relationships among concepts used in various design object models. This paper proposes a framework of the pluggable metamodel mechanism that allows to plug in existing design tools, to support a modeling on it, and to maintain consistency among them. We describe a prototype system and illustrate an example of ball screw design.

English, Scientific journal, This paper examines the effectiveness of different phrase identification and weighting methods for Japanese text retrieval in an operational information retrieval (IR) system, called NACSIS-IR. Based on our previous experiments, we used character-based indexing with positional information and word-or phrase-based query processing, which allowed us to implement sophisticated linguistic analysis on large-scale databases while maintaining adequate efficiency. The results of retrieval experiments on a large-scale Japanese test collection showed that the combination of enhanced phrase identification using patterns defined over part-of-speech tags and our algorithms Phrase2 and Phrase5 made a significant positive contribution to retrieval effectiveness. The paper also discusses indexing and phrase processing of Japanese or East Asian languages.

Scientific journal, An intelligent CAD system aims at serving a designer as an intelligent, integrated design environment. For building such a system, development of a large scale knowledge base is necessary. To do so, design knowledge must be systematically formalized, made computable, and organized. Design knowledge has two categories ; i.e., design object knowledge and design process knowledge. In our previous reports, we have formalized a computable design process model to represent design process knowledge and the concept of a metamodel dealing with multiple design object models.

English, International conference proceedings, An extension of the Function-Behavior-State (FBS) diagram is proposed for representing a function in the computer aided conceptual design process. The new FBS method uses three additional concepts, namely: function body, function modifier and object entity, to represent the designers' intention more precisely than the original FBS diagram. The performance of the proposed method is complemented by the Functional Evolution Process (FEP) model which represents the different design processes.

Design process model with multiple design object models

International conference proceedings, An intelligent CAD system is not merely a set of intelligent design tools, but rather it must be an intelligent, integrated design environment. This requests it must be equipped with a large scale knowledge base in which design knowledge is intensively and systematically stored. To do so, design knowledge must be systematically formalized, made computable, and organized. The present paper investigates fundamental issues of systematization of design knowledge. Design knowledge has two categories; i.e., design object knowledge and design process knowledge. In our previous reports, we have formalized a computable design process model to represent design process knowledge and the concept of metamodel dealing with multiple design object models. This paper proposes a framework to achieve harmonized combination of these two. In this framework, the computable design process model navigates the metamodel mechanism to generate and modify models of the design object. We describe a prototype system and illustrate an example of ship design.

Proposal of qualitative reasoning system that has more compatibilitywith large language model based on physical laws and principles.
YOSHIOKA Masaharu, SUZUKI Shinpei, Proceedings of the Annual Conference of JSAI, JSAI2024, 3Xin228, 3Xin228, 2024
Recent development of Large Language Model (LLM) allows the user to obtain the explanation of physical phenomenon as text. However, the output of LLM may contain inappropriate explanation, and it is not easy to justify the appropriateness of the generated text. To solve this problem, we have proposed a framework to construct a model for qualitative reasoning system based on the text analysis results of LLM (e.g., a list of objects and physical phenomena). In this paper, we propose a qualitative reasoning system that has more compatibility to interpret the output of LLM and demonstrate the system with simple physical behavior simulation., The Japanese Society for Artificial Intelligence, Japanese

Model construction method for qualitative reasoning based on the recognition results of physical laws and principles by large language models
SUZUKI Shinpei, YOSHIOKA Masaharu, Proceedings of the Annual Conference of JSAI, JSAI2024, 3Xin227, 3Xin227, 2024
The Large Language Model (LLM) has recently been developed and has demonstrated impressive performance in solving a variety of tasks. However, LLMs still face challenges when solving tasks that require the combination of multiple rules simultaneously. For instance, behavior analysis based on physical laws and principles is one such task. This paper proposes using qualitative reasoning as a framework to combine multiple physical laws and principles for behavior analysis. Furthermore, we propose a method for constructing a model for qualitative reasoning based on the output of LLM. The analysis of a basic physics problem illustrates this method. This method takes advantage of the strengths and compensates for the shortcomings of both LLM and conventional qualitative reasoning model., The Japanese Society for Artificial Intelligence, Japanese

Classification of articles using Wikipedia categories and definition sentences
SUZUKI Nozomi, YOSHIOKA Masaharu, Proceedings of the Annual Conference of JSAI, JSAI2024, 4Xin284, 4Xin284, 2024
There have been several attempts to extract knowledge from Wikipedia. One of the most important information to be extracted is the classification of articles. The Wikipedia category, which classifies the group of articles for ease of navigation, seems to be a good resource for this task. However, since Wikipedia categories are also used for different purposes and many categories are added to an article, it is necessary to select the representative Wikipedia category for better classification. In this paper, we propose to use the definition sentence, which is the first sentence of the article, to select the representative category among them. In this method, we extract the definition word, which is for representing the class of the article, from the definition sentence. We also propose a method to classify the article using this information and categories, and evaluate the method using the SHINRA dataset., The Japanese Society for Artificial Intelligence, Japanese

The Analysis of Wikipedia Category Ontology: Proposal of new category types and analysis using them
EBISUI Yusuke, YOSHIOKA Masaharu, Proceedings of the Annual Conference of JSAI, JSAI2024, 3Xin229, 3Xin229, 2024
Wikipedia is one of the largest online encyclopedias, and there have been attempts to extract structured knowledge from Wikipedia, such as DBpedia, YAGO, and the Japanese Wikipedia Ontology. We have proposed the Wikipedia Category Ontology, which categorizes the types of Wikipedia categories and the relationships between them. In this framework, there are two main types of categories. One is a set category, which represents concepts such as "country" and "university". The other is a topic category, which represents specific topics such as "Japan" and "Hokkaido University". These classifications are decided based on the meaning of the Wikipedia category labels. However, based on the analysis of the actual role of categories in each article, there are certain categories whose articles are not instances of the category. In this paper, we analyze the Wikipedia Category Ontology and propose a new definition and a new method for category classification based on this analysis., The Japanese Society for Artificial Intelligence, Japanese

We have been working on the project to develop a new research paper database that collects papers from the particular domain and extracts important terms to analyze the cooccurrence among them. This system has been applied to the research domain of nanocrystal device development for evaluation. In this paper, to discuss the generality of the proposed system, we have applied the system to the domain of organic chemical reaction development, which is similar to the previous domain. In this domain, there are open databases for representing the chemical substance and information extraction tool. These tools are good for making the initial database, but we confirm it is also necessary to consider the variation of representing the same chemical substance in different string., The Japanese Society for Artificial Intelligence, Japanese

Wikipedia Category Ontology - Utilization of Wikipedia category from the view point of knowledge engineers -
YOSHIOKA Masaharu, JSAI Technical Report, Type 2 SIG, 2021, 55, 5, 5, 2021

Wikipedia is one of the largest knowledge resources available via the Internet. Several methods have been proposed for extracting knowledge/information from Wikipedia, but methods based on extracting knowledge from the Wikipedia category structure can not utilize whole part of its structure because of the complexity of the relationships between the various categories. In this paper, we briefly review our previous researches on analyzing Wikipedia category and introduce a framework called "Wikipedia Category Ontology" (WCO) that aims to act as a basis for interpreting the Wikipedia category structure. It is based on a classification of category types and relationship types and available online in the form of Linked Open Data at http://wcontology.org/. We also demonstrate the system by using Wikipedia category analysis scenarios.

Since a category of Wikipedia contains information useful for classifying a Wikipedia pages. A classification method using this category information has been proposed.However, since various types of information are mixed in the Wikipedia category, there is a problem that a category that is not appropriate to be assigned at the same time is added.In this research, we classify more appropriate classes for pages with multiple categories using Wikipedia category ontology, which defines the types of Wikipedia categories and their parent-child relationships. By using this method, we rank the adequacy of the page class belonging to a plurality of categories. To confirm effectiveness of this method, we compar with the classification of SHINRA : Wikipedia Structuring Project.

Feasibility study for technical documents retrieval system in construction industry
FURUKAWA Kei, YOSHIOKA Masaharu, Proceedings of the Annual Conference of JSAI, 2020, 0, 3Rin470, 3Rin470, 2020

Lots of technical documents have been created and accumulated for the purpose of standardizing and inheriting technologies in many companies across industries. Those documents have certain formats and can be searched by documents retrieval systems. However, since many of those documents are written in specific fields, it's difficult for younger engineers to find the documents related to their tasks if they don't know appropriate key words whereas it's easy for experienced engineers who know the existence of such documents. In this study, we conduct feasibility studies to reveal the above problems with documents in a construction company as an example and introduce the basic idea of the new technical documents retrieval system utilizing construction steps and conditions.

Stock price forecasting is performed in various forms, such as technical analysis and fundamental analysis using time series data and financial indicators, and text analysis using news information. We propose a method for predicting stock prices by machine learning using multiple technical indicators, taking into account the increasing number of algorithmic trades using technical analysis. At this time, stocks with good and bad fits by technical analysis are classified and evaluated. We consider how to combine multiple technical indicators.

NAKAGAWA Takanori, YOSHIOKA Masaharu, Proceedings of the Annual Conference of JSAI, 2018, 0, 2F402, 2F402, 2018

Since Wikipedia is an on-line encyclopedia that covers varieties topics, there are several attempts to extracting knowledge from its contents. Wikipedia category is one type of information that provides topical index for the articles and organized as hierarchical manner. However, since hierarchical structure of Wikipedia category have different characteristics compared to the one for knowledge representation, it may not fully and correctly utilized at this moment. In this paper, we propose a method to extract hierarchical structure that have similar characteristics with knowledge representation.

NaDev: An Annotated Corpus to Support Information Extraction from Research Papers on Nanocrystal Devices
Thaer M. Dieb, Masaharu Yoshioka, Shinjiro Hara, 情報処理学会論文誌, 57, 4, 15 Apr. 2016
The process of nanocrystal device development is not well systematized. To support this process, analysis of the information produced by developmental experiments is required. In this study, we constructed an annotated corpus to support the extraction of experimental information from relevant publications. We designed the corpus-construction guidelines by cooperating with a domain expert. We evaluated these guidelines through corpus-construction experiments with graduate students from this domain, and then evaluated the corpus with the domain expert. In the corpus construction experiments, we achieved a sufficient level of Inter-Annotator Agreement by using a loose agreement measure that ignored the term-boundary mismatch problem, and made an agreement corpus that excluded annotations based on misunderstanding the guidelines. The domain expert evaluated this agreement corpus and modified the guidelines based on real examples. Using these guidelines, we finalized the corpus called "NaDev" (Nanocrystal Device development corpus). The NaDev corpus and its construction guidelines will be released via our website, http://nanoinfo.ist.hokudai.ac.jp/. The NaDev corpus aims to support automatic information extraction from publications relevant to nanocrystal device development. This information can be used to solve problems in the nanotechnology domain using the massive availability of fresh information. To the best of our knowledge, this is the first corpus constructed for the development of nanocrystal devices.\n------------------------------This is a preprint of an article intended for publication Journal ofInformation Processing(JIP).

We have been working on the project "Exploring knowledge for nanodevice development" and proposed a framework to annotate useful information (e.g., source material, evaluation parameter, and so on) for analyzing nanocrystal device development papers. In this paper, we conduct nanocrystal device research papers clustering experiment once on annotated papers using automatic annotation results, and once as non-annotated using bag of word approach, and then we compare the results discussing the usefulness of the automatic annotation.

Discovery and Maintenance of Links between Wikipedia and GeoNames by Using Wikipedia Category
吉岡 真治, 劉 亦奇, 神門 典子, 情報処理学会論文誌データベース（TOD）, 5, 3, 141, 148, 28 Sep. 2012
Recently, due to the higher demand for geographic information system, it is necessary to have a good geographical database for such systems. GeoNames is one of the largest geographical database as Open Data. This database is also used for constructing web ontology by adding links to the Wikipedia page as a part of Linked Open Data. Even though, here are several attempts to find links automatically, the number of links between GeoNames and Wikipedia is not sufficient. In this paper, we propose an automatic link discovery method to use Wikipedia categories to identify the correspondence between Wikipedia page and GeoNames entry. We also propose to use this method for inappropriate link detection. Link data obtained in this paper is already sent to the manager of GeoNames and a part of the result is used for updating the site., 情報処理学会, Japanese

Estimation and Analysis of Topic Models in Time Series Japanese / Chinese News and Blogs

This paper studies issues regarding topic modeling of information flow in multilingual news and blog streams. If someone wants to find differences in the topics of Japanese and Chinese news / blog, it is usually necessary for him/her to carefully watch every article in Japanese and Chinese news streams at every moment. In such a situation, topic models such as LDA (Latent Dirichlet Allocation) and DTM (dynamic topic model) are quite effective in estimating distribution of topics over a document collection such as articles in a news / blog stream. Based on the results of estimating distribution of topics in Japanese / Chinese news streams, this paper proposes how to analyze cross-lingual alignment of topics in time series Japanese / Chinese news streams. This paper also proposes how to analyze differences of concerns and opinions among various Chinese news sites as well as blog hosts., The Institute of Electronics, Information and Communication Engineers, Japanese

Research on the Automatic Classification of Anchor Texts for utilizing Web links
OHTSUKA Hiroki, YOSHIOKA Masaharu, IPSJ SIG Notes, 94, 35, 9, 14, 18 Mar. 2009
A Link Structure among Web documents represents the relationship among these documents. Web structure analysis methods such as PageRank use this information. However, most of these methods pay little attention to the type of link (e.g., most of the methods use simple classification such as link to the same site or not). In this research, we proposed a method to classification criteria of anchor texts based on the role analysis of the text in Web documents for better link structure analysis and the users' behavior analysis on the Web page. In this paper, we propose an automatic classification method based on the result of manually classification experiment. In order to evaluate this method, we compare the result of automatic classification results with manually classified ones., Information Processing Society of Japan (IPSJ), Japanese

In order to utilize news articles from multiple news sites, it is better to understand the characteristics of each news site. In this paper, a concept of contrast set mining is applied for analyzing the characteristic difference between each news site and all others. The News Site Contrast (NSContrast) system is also proposed based on this mining technique.

Development of Universal Abduction Studio (14th report):Web-based expansion scheme for a design knowledge information database

In recent years, comprehensive problem solving by a designer has been required as the demand for an artifact grows and complicates more. In the above background, we have proposed Universal Abduction Studio (UAS), a computer environment, which supports a creative design synthetically. However, it is difficult for a designer to acquire the multiple domain knowledge on the grounds that the knowledge is accumulated manually. This paper proposes a method of expanding the design knowledge database used in UAS by extracting useful information for design from the resource on the web. Also, the authors propose a filtering method for reducing the information which isn't useful for design from the database. At the end, the effectively of the methods is verified., The Japan Society for Precision Engineering, Japanese

1311 A knowledge representation for the creative design support using knowledge tagged by the surface case
SUGIYAMA Aki, SHIMOMURA Yoshiki, YOSHIOKA Masaharu, TAKEDA Hideaki, The Proceedings of Design & Systems Conference, 2008, 0, 181, 185, 2008
In order to realize a creative design, it is thought to be important to unify the knowledge from different knowledge areas flexibly. The computer environment that supports designers in an integrated way has been developed. The extended method of the knowledge representation forms for increasing the usefulness of the hypothetical knowledge from the knowledge tagged with vocabulary information was proposed. However, the current method isn't always capable of obtaining the useful knowledge, since it doesn't consider the context. In order to acquire the hypothetical knowledge adapted to the context efficiently, the tagging technique based on the attribute of a vocabulary and the reasoning using it are effective. In this paper, the authors propose knowledge representation forms for tagging physical quantity based on vocabulary describing knowledge, and verify the usefulness of the proposed method., The Japan Society of Mechanical Engineers, Japanese

We argue that abduction for integrating theories can be a basic principle to formalize creative design processes. Based on this principle, we have proposed Universal Abduction Studio, a design environment in which designers combine different theories to arrive at better design. In this new approach to computational support of conceptual design, the system should offer various types of abductive reasoning from which designers can select an interesting design method. This paper aims at proposing the method of handling terminology by general common ontology and managing in the multiple. We also discuss technologies to implement proposed method of managing terminology., The Japan Society of Mechanical Engineers, Japanese

Proposal of an Analysis Method for Evaluating the Effectivess of Query Term Expansion in Information Retrievval
YOSHIOKA Masaharu, IPSJ SIG Notes, 81, 108, 53, 60, 02 Nov. 2005
Query term expansion is a technique to modify initial query by adding some terms that represents users' information need for achieving higher retrieval performance. However, a good framework for evaluating this technique in isolation does not exist because the effect of query expansion depends on several issues. In this paper, I enumerate several features that may affect the quality of this technique and analyze retrieval experiment results by using these features., Information Processing Society of Japan (IPSJ), Japanese

Analysis on Effectiveness of Query Terms in Information Retrieval Test Collection

In many cases, it is not easy for a user of Information Retrieval (IR) to select appropriate query terms for representing his/her information need. Since this mismatch between query terms and information need affects the topic difficulty, it is better to have a framework to evaluate the effectiveness of the query terms. Therefore, in this paper, I propose some feature quantities that characterize quality of initial query in test collection. I also analyze correlation coefficient between these quantities and retrieval performance by using NTCIR-4 web test collection., Information Processing Society of Japan (IPSJ), Japanese

For tracing or finding the lost goods, we need active-type of RFID tags with built-in batteries, but those active tags have significant drawbacks such as the higher hardware cost and the finite battery lifetime. In this paper, we propose "double-decker" RFID tags, which can be separated into the two parts of ID tags. The new type of RFID tag is useful and cost-effective for tracing/keeping of a large number of goods. We present the basic structures of the double-decker tags and show some typical applications., Information Processing Society of Japan (IPSJ), English

2306 Research on Extraction of Stake Holder Network for Program Management
YOSHIOKA Masaharu, The Proceedings of Design & Systems Conference, 2005, 0, 334, 337, 2005
Program management aims to support a management for a large and complex project. We have already proposed a framework for supporting this management process by reviewing a program from three different aspects (i.e., process planning, related information, and stake holder networks). However, this system only supports to represent and review a program by using manually inputted information. In this paper, I proposed a system that extract stakeholders information from a text to support constructing stake holder network. In this system, we categorize stakeholders in two types. One is collaborator and the other is opponent. For extracting these two types of stakeholders, we collected typical expression for describing them and made pattern match rule for extraction. For evaluating our methodology, we implemented the prototype system that uses Japanese newspaper articles as a resource for extraction., The Japan Society of Mechanical Engineers, Japanese

A Query-Driven Construction of Maximal Analogies from Documents
HARAGUCHI Makoto, YOSHIOKA Masaharu, IPSJ SIG Notes, 162, 73, 7, 10, 15 Jul. 2004
We present here a method for constructing a common abstract event sequence from two or more documents also regarded as event sequences. To reduce the computational cost and to improve the precision of relevance judgement made by the abstract event sequences, we introduce a notion of base queries and consider a retrieval process to find an instance of base query that is similar to a given family of instance documents. By the base query and its instance documents, we can design a divide and conquer strategy for the construction of abstract common event sequence from the instances., Information Processing Society of Japan (IPSJ), Japanese

Research on Information Retrieval System based on Adaptive Generalization (2nd Report) : Construction of IR User Interface that focuses on Generalized Concept with High Coverage
YOSHIOKA Masaharu, HARAGUCHI Makoto, IPSJ SIG Notes, 74, 36, 87, 93, 26 Mar. 2004
It is not easy for a user of Information Retrieval (IR) system to select appropriate keywords. In this research, we proposed a new IR system that uses adaptive generalization of keywords. When the system can selects appropriate generalization by estimating user's intent, the system can generate good keywords that have high readability and good retrieval performance. In this report, we proposed new IR user interface that displaies generalized concepts by using relevant documents information. In addition, we propose a method to construct Boolean retrieval formula by using these generalized concepts and apply this method for Web information retrieval., Information Processing Society of Japan (IPSJ), Japanese

In order to obtain a creative design solution, which is not obtained only with existing design knowledge, it is required to unify different knowledge groups, which exist independently, and to perform gradual extension of knowledge. Authors have proposed some knowledge representations and algorithms of knowledge integration for realizing knowledge extension with the aim of development of "Universal Abduction Studio", which supports creative design synthetically. In this paper, the fundamental framework for dealing with information as knowledge is proposed. And the representation and the knowledge integration based on it are proposed., The Japan Society of Mechanical Engineers, Japanese

Given two or more similar documents in the form of texts, we present a notion of maximal analogies representing maximal sequences consisting of pairs of similar events in the documents. They are required to satisfy certain cost condition so that meaningless similarities between documents are never concluded. A bottom-up search procedure to find a maximal analogy satisfying the cost condition is also presented. In addition to the set of similar documents, we suppose another set of dissimilar ones. Then a maximal analogy is furthermore tested for their appropriateness so as not to explain the latter ones. The test can be performed by an effective subsumption check procedure., Information Processing Society of Japan (IPSJ), Japanese

It is not easy for a user of Information Retrieval (IR) system to select appropriate keywords. Therefore, many IR systems have capability to modify keywords by estimating user's intent. However, since modified keywords are usually represented as complicated form, it is difficult to judge the appropriateness of them. In this research, we proposed a new IR system that uses adaptive generalization of keywords. when the system can selects appropriate generalization by estimating user's intent, the system can generate good keywords that have high readability and good retrieval performance. In this report, we proposed to use the contribution value of each keyword for relevance judgement to select appropriate generalization. In addition, we confirm general concept structure stored in a thesaurus is not sufficient for representing particular user's intent. Therefore, we proposed a purpose oriented method to modify concept structure., Information Processing Society of Japan (IPSJ), Japanese

A Proposal of CAD Mechanism for Design Knowledge Management
Nomaguchi Yutaka, Yoshioka Masaharu, Tomiyama Tetsuo, Transactions of the Japanese Society for Artificial Intelligence, 17, 17, 104, 113, 2002
In this paper, we propose a fundamental idea of a new CAD mechanism to facilitate design knowledge management. This mechanism encourages a designer to externalise his/her knowledge during a design process and facilitates sharing and reuse of such externalised design knowledge in later stages. We also describe the implementation of this idea called DDMS (Design Documentation Management System). DDMS works as a front end to KIEF (Knowledge Intensive Engineering Framework), which we have been developing. We also illustrate an example of machining tool design to demonstrate the features of DDMS., The Japanese Society for Artificial Intelligence, Japanese

Construction of a Large Scale Test Collection NTCIR-2 : The Effect of Cross-Lingual Pooling on Evaluation
KURIYAMA Kazuko, YOSHIOKA Masaharu, KANDO Noriko, IPSJ SIG Notes, 63, 74, 9, 16, 24 Jul. 2001
The purpose of this study is to examine whether there is an effect on the relative evaluation of the IR systems using the relevance judgments made by the pooling method and additional interactive searches. We carried out experiments using different lists of relevance judgments and search results submitted for the test of the 2nd NTCIR Workshop. First, we evaluated the search results using the list of the final relevance judgments F of NTCIR-2 and F-I, that is, the F without the unique relevant documents found by the additional interactive searches I. Second, we made pools from the search results for each of the sub-tasks and evaluated the search results using the pools as lists of relevance judgments. Almost the same rankings of the search results were produced by using the pools as lists of relevance judgments for system evaluation. Therefore our results verified the reliability of test collection as an evaluation tool, which was based on pooling method., Information Processing Society of Japan (IPSJ), Japanese

Information Retrieval System Evaluation using Multi-grade Relevance Judgments : Discussion on Averageable Single-numbered Measures
KANDO Noriko, KURIYAMA Kazuko, YOSHIOKA Masaharu, IPSJ SIG Notes, 63, 74, 105, 112, 24 Jul. 2001
This paper proposes new measures, weighted R precision and wighted average precision, for information retrieval(IR) system testing with ranked output based on multi-grade relevance judgments. Relevance judgments are one of the most fundamental factors in evaluation of search effectiveness of IR systems. Intuitively, the highly relevant documents are more important for users than partial relevant ones and the documents retrieved in the higher ranks in the ranked list are more important. Therefore the systems producing the search results in which higher relevant documents in higher ranks in the ranked list should be rated as better thought relevance judgments must be done in binary to calculate traditional IR system evaluation measures "recall" and "precision". Based on the review of existing IR system evaluation measures, we decided that either of proposed measures is single number and averageable over number of runs. The paper then shows the evaluation results of the Japanese IR task at the second NTCIR Workshop, in which four-grade relevance judgments, highly relevant, relevant, partially relevant, and irrelevant, were used. Finally implications of "partial relevance" are discussed in the relation to user-oriented IR system evaluation studies., Information Processing Society of Japan (IPSJ), Japanese

A proposal of design reasoning model that takes notice of design knowledge (the Third Report) : A proposal of a synthesis language for describing design operational knowledge
YOSHIOKA Masaharu, Takeda Hideaki, WASHIO Takashi, TOMIYAMA Tetsuo, The Proceedings of Design & Systems Conference, 2001, 0, 281, 284, 2001
Since design knowledge plays a crucial role in design process, we are conducting research on design reasoning model that takes notice of design knowledge. To make a design reasoning model, we have already proposed a reasoning framework of design and analyzed basic operations for the framework. However, since these operations are just fragments of whole design process, it is necessary to describe design operational knowledge that can control the entire reasoning operations by constructing the sequence of these fragments. So, in this paper, we propose a synthesis language for describing design operational knowledge., The Japan Society of Mechanical Engineers, Japanese

2314 Advances in Research into Artifacts (The 15th Report) : Knowledge Acquisition by Discovering the Designer's Thought Patterns
Sakai Hiromitsu, Nomaguchi Yutaka, Yoshioka Masaharu, Shimomura Yoshiki, Tomiyama Tetsuo, The Proceedings of Design & Systems Conference, 2001, 0, 204, 206, 2001
In engineering activities, management of designers' knowledge is becoming crucial to share and reuse it efficiently. Toward this issue, we are studying a methodology to capture the designer's thought process, and to semi-automatically arrange it into a refined document, which addresses a particular objective with particular thought patterns. The key issues of this methodology are to acquire the thought patterns and to define relations among them. This paper reports our algorithm to acquire thought patterns from a record of designer's thought processes and any other types of documents including patent documents and academic papers. We employ a knowledge discovery approach which is recently discussed in data mining research., The Japan Society of Mechanical Engineers, Japanese

3104 Design for Upgradable Products Considering Future Uncertainty

Conventional products tend to be thrown away because of functional obsoleteness before reaching the end of physical life of the products. This is one of the main causes of the mass disposal problem. In order to solve this problem, this paper proposes a design methodology for upgradable products. Especially, this paper discusses a method dealing with uncertainty of long-term planning in the design methodology. The proposed method deals with uncertainty as ranges of parameter values, and derives a design solution that realizes required upgrades, while adapting to estimated uncertainty. This method makes a design object robust and tolerant against the uncertainty and, therefore, makes design for upgradability more feasible., The Japan Society of Mechanical Engineers, Japanese

3305 Research on knowledge management system that harmonize the document information and well formalized knowledge
YOSHIOKA Masaharu, SHAMOTO Yasuhiro, The Proceedings of Design & Systems Conference, 2001, 0, 321, 324, 2001
In engineering activities, engineers solve various kinds of problems. Most of these problems are routine problems that are easy to formalize and formalized knowledge is useful for these problems. On the other hand, there are complicated problems that is difficult to formalize all of the problem solving process. One of the useful information to solve such complicated problems is result of the similar problem solving process. In addition, later in such complicated problem solving process, most of the decomposed subproblems are able to handle as routine problems. In this research, we decide to use formalized knowledge and document information that represents the history of problem solving processes to support to solve both types of the problem. For that purpose, we propose a new knowledge management system that supports a user to solve the problem through document processing. In this support process, the system retrieves related documents for user's problems by using formalized knowledge and information retrieval techniques. After retrieving related documents, he/she modifies them to fit his/her problems. Modified information is associated with the formalized knowledge and stored as documents for future reuse., The Japan Society of Mechanical Engineers, Japanese

Building Japanese Compound Analyzer Using Lexical Restriction
TAKEUCHI Koichi, UCHIYAMA Kiyoko, YOSHIOKA Masaharu, KAGEURA Kyo, KOYAMA Teruo, IPSJ SIG Notes, 57, 29, 71, 78, 21 Mar. 2000
The aim of our research is to build a Japanese compound analyzer using grammatical constraint. To analyze the compounds which have verbs in their heads is to reveal the relationship between incorporated nouns and the head verbal nouns. The kind of relationship is adjunctive and internal argument of a head verb. In our previous research, we categorize verbs based on their argument structure and lexical conceptual structure (LCS), but it is necessary to categorize nouns to reveal the relationship between a noun and a head verb in compounds. Therefore we propose the method to categorize nouns based on argument structure and LCS of head verbs in this paper. In the case of categorization, we also use qualia structure of generative lexicon. After the assumptions of restriction about categorized nouns is constructed, we attempt the experiment of analyzing technical terms (103 words) in the domain of information processing. Finally we show the experimental results that 92 words (89%) can be solved using our restriction and discuss the limitation of our model., Information Processing Society of Japan (IPSJ), Japanese

In the previous research of analyzing compound words, the technique using statistics of word co-occurrence is well known. However, since some grammatical and semantic restrictions must control the construction of compound words, only the statistical technique is not enough to analyze compound words. In this paper, we analyze technical terms that consist of two nouns whose head is verbal noun by means of the rich lexical knowledge that are a level ordering assumption, an argument structure and a lexical conceptual structure used on morphology or syntax. We will show the following three results: 1) there are only two kinds of relationship that is a modifier or a argument for a verbal noun in the relationship between two words in a compound word, 2) the analysis of compound words depends on argument structure of verbal noun, and 3) the structure of some compound words are changed according to the context. Finally we discuss constructing compound words analyzer from the results., National Institute of Informatics, Japanese

It is difficult problem to know how to prepare lexical knowledge in order to analyze Japanese compound words. In this paper, we analyze technical terms that consist of two verbal nouns by means of the rich lexical knowledge that are a level ordering assumption, an argument structure and a lexical conceptual structure used on morphology or syntax. Our analysis of compound words aims to reveal the relations between the constituent words of compound words. From the results, our method can explain some parts of phenomena of the impossible compound words and the conversion of verbal noun into noun in compound words. The lexical knowledge we have assumed is aimed at describing the details of verbal nouns. While analyzing verbal nouns, we also clarify how to describe the lexical knowledge of noun words., The Institute of Electronics, Information and Communication Engineers, Japanese

Reserach on Design Documentation Management System
Yoshioka Masaharu, Nomaguchi Yutaka, Tomiyama Tetsuo, IPSJ SIG Notes, 99, 88, 63, 68, 21 Oct. 1999
In a design process, the designer uses a variety of information and knowledge for generating design solution and evaluating it. These types of process information are useful not only for understanding the design rationale but also for the source of designers' knowledge. Therefore, many companies try to store these types of information as design documents. However, since most of the documents are made for explaining the design solution after finishing whole design, most of the documents do not cover all of information in design process. In addition, there is not good framework to retrieve and reuse these documents and that prevents the designers to reuse these useful documents. For tackling these problems, we have proposed the design documentation management system. This system can record design documents as a result of design process. The system can also retrieve and reuse related design documents based on the design context. In this report, we discuss the Japanization of the design documentation system and application of text retrieval technique., Information Processing Society of Japan (IPSJ), Japanese

A Study for Connections among Constituent Elements of Nominal Compounds : An Evaluation of Grammatical Categories based on Grammatical Characteristics

Technical compound nouns are often used as keywords for information retrieval. The mechanism how nominal compounds are generated can be clarified by analyzing internal structures of nominal compounds. The conventional approach has centered on the analysis of semantic relations among constituent elements of nominal compounds. We think structural and grammatical characteristics play the key role in nominal compounds. In our study, we propose original categories in terms of structural and grammatical characteristics, and examine modifications and connections among constituent elements of compound words, using the original categories., The Institute of Electronics, Information and Communication Engineers, Japanese

There are several types of research articles; e.g., survey articles, those that propose new technologies, those that apply existing technologies to unsolved problems. In this paper, I propose a methodology to categorize these types of research articles by analyzing roles of the author added keywords. First, I categorize verbs that are frequently used in research articles into five role categories. Second, I propose methodology to analyze roles of the keywords by using the categories of verbs. To validate this methodology, I apply it to the real research articles and explain its result., National Institute of Informatics, Japanese

We are currently constructing the terminology-motivated corpus (the NACSIS corpus) as a part of the NACSIS test collection project. There are two issues to constructing this corpus. One is a definition of domain that makes the terminology research different from IR keyword one. The other is a definition of lexical units in the texts that gives basic unit for terminology operations. In this paper, we discuss the approach to design the NACSIS corpus for solving these two issues, and show the status of NACSIS., Information Processing Society of Japan (IPSJ), Japanese

The Development of Knowledge Integrated Engineering Framework Based on Ontology ("Ontology : Foundations and Applications")
SEKIYA Takayuki, YOSHIOKA Masaharu, TOMIYAMA Tetsuo, Journal of the Japanese Society for Artificial Intelligence, 14, 6, 1051, 1060, 1999

During design, a designer uses various computational tools, such as a geometric modeling system, analysis tools, and databases. To support these design processes, a system that can integrate such computational tools is required. For this purpose, we have been developing the Knowledge Intensive Engineering Framework (KIEF) system. KIEF enables the designer to build, evaluate, and modify design models on the system by providing him/her with a wide variety of engineering knowledge. A common ontology plays an important role in integrating tools and representing engineering knowledge. This paper describes the structure of the ontology in KIEF, and how it is used in a modeling processes on KIEF.

Aplication of Knowledge Intensive Engineering to Architectural Design
Yoshioka Masaharu, Research bulletin of the National Center for Science Information System, 10, 0, 73, 79, Mar. 1998
Because of the finiteness of natural resources, environmental problems and so on, engineers are expected to evaluate their products from ever more various kinds of aspects. To support such claim, we proposed the concept of knowledge intensive engineering, in which various kinds of knowledge is used in a flexible and integrated manner in order to aim at generating more added-value. In addition, we also proposed Knowledge Intensive Engineering Framework (KIEF) system that forms a computational framework of knowledge intensive engineering. In this paper, I describe the concept of knowledge intensive engineering and the KIEF system. After that, I apply the KIEF system to architectural design to show the value of the system. To do so, I analyze knowledge that is used in architecture design and discuss how to implement the knowledge on the KIEF system. Finally, I show some results of this application and discuss the capability of the KIEF system., National Institute of Informatics, Japanese

A Study on an Integrated Modeling Environment for Design: A Proposal of the Pluggable Metamodel Mechanism
YOSHIOKA Masaharu, TOMIYAMA Tetsuo, Journal of the Japanese Society for Artificial Intelligence, 13, 2, 312, 319, 1998

In this study, we propose a framework of an integrated modeling environment for design. Since a mechanical engineering design process requires various kinds of design object models, such as a geometric model, a kinematic model, and a finite element model, this environment should maintain consistency among these models. Furthermore, commercial design tools are practically used in design processes, and these must be integrated as well. For dealing with multiple design object models, we have formalized a concept called a metamodel. A metamodel is a model which represents relationships among concepts used in various design object models. This paper proposes a framework of the pluggable metamodel mechanism that allows to plug in existing design tools, to support a modeling on it, and to maintain consistency among them. We describe a prototype system and illustrate an example of ball screw design.

Supporting conceptual design based on the function-behavior-state modeler
Y Umeda, M Ishii, M Yoshioka, Y Shimomura, T Tomiyama, AI EDAM-ARTIFICIAL INTELLIGENCE FOR ENGINEERING DESIGN ANALYSIS AND MANUFACTURING, 10, 4, 275, 288, Sep. 1996
The relative significance of conceptual design to basic design or detail design is widely recognized, due to its influential roles in determining the product's fundamental features and development costs. Although there are some general methodologies dealing with functions in design, virtually no commercial CAD systems can support functional design, in particular so-called synthetic phase of design. Supporting the synthetic phase of conceptual design is one of the crucial issues of CAD systems with function modeling capabilities. In this paper, we propose a computer tool called a Function-Behavior-State (FBS) Modeler to support functional design not only in the analytical phase but also in the synthetic phase. To do so, the functional decomposition knowledge and physical features in the knowledge base of the modeler, and a subsystem Qualitative Process Abduction System (QPAS) play crucial roles. Modeling scheme of function in relation with behavior and structure and design process for conceptual design in the FBS Modeler are described. The advantages of the FBS Modeler are demonstrated by presenting two examples; namely, an experiment in which designers used this tool and the design of functionally redundant machines, which is a new design methodology for highly reliable machines, as its application., CAMBRIDGE UNIV PRESS, English

A Design Process Model for Handling Multiple-Design-Object Models.
Yoshioka Masaharu, Nakamura Masahiko, Tomiyama Tetsuo, Yoshikawa Hiroyuki, TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 61, 581, 330, 337, 1995
An intelligent CAD system aims at serving a designer as an intelligent, integrated design environment. For building such a system, development of a large scale knowledge base is necessary. To do so, design knowledge must be systematically formalized, made computable, and organized. Design knowledge has two categories ; i.e., design object knowledge and design process knowledge. In our previous reports, we have formalized a computable design process model to represent design process knowledge and the concept of a metamodel dealing with multiple design object models. This paper proposes a framework to achieve a harmonized combination of these two. In this framework, the computable design process model navigates the metamodel mechanism to generate and modify models of the design object. We describe a prototype system and illustrate an example of ship design., The Japan Society of Mechanical Engineers, Japanese

Yoshioka Masaharu
In this research, we proposed a method to analyze news site stance of particular news topic using the distribution of polarity of the articles published by the news site from multiple perspectives. In this research, we confirmed that it is important to understand the interests on subtopics and/or genres of the news articles for detailed analysis of the news site stance. Based on this understanding we proposed a system that can analyze news site stance interactively by taking account the polarity of the related news articles for multiple subtopics and/or genres.
We also proposed Wikipedia category ontology that is new knowledge resource extracted from Wikipedia category from the viewpoint of knowledge engineering. This new knowledge can be used for analyzing the type of the named entity.

When we read several stories or legal cases, we often find relational similarities between objects in spite of the difference of stories they belong to. The goal of this research is to design and implement an efficient algorithm for finding those structural similarities among more than two domains. For this purpose, we have designed such an algorithm making use of Non-Negative Matrix Factorization and Graph Mining techniques. The algorithm we have obtained is effective not only for text analysis but also for mining similar structure among databases as data warehouses.

In this project, we have constructed a corpus for extracting useful information related to the experiment of nanocrystal device development (e.g., Source material and parameters) and developed an automatic information extraction system NaDev that tries to extract such information from papers. By using NaDev, we can extract characteristic keywords related to the experiment (e.g., source material, experimental parameter) and these extracted keywords are used for calculating similarity among different papers and information retrieval system that have query construction support. In this project, we proposed a figure retrieval system that uses such parameter information as query.

吉岡 真治, 原口 誠, 大久保 好章
本研究では、情報抽出元である各々のWebサイトが持つ情報の偏りなどの特徴を分析する方法を提案すると共に、この特徴分析の結果を踏まえた意見集約・分析の方法を提案している。具体的には、全てのデータセットを含む全体のデータベースと特定の条件を満たす部分データベースにおけるデータの分布の違いに注目したコントラストセットマイニングを適用することにより、個々のサイトの特徴を分析する方法を提案する。
この目標に対して、本年度は、「コントラストセットマイニングによる個々のサイトの特徴分析」の考え方に基づくシステムを実装し、様々なレベルのユーザ実験を通した評価を行った。簡単にシステムを使用してもらってコメントをもらうというユーザ実験では、半数以上の利用者から、システムが有用であるというコメントをもらえた。一方、レポート作成課題の実施という本システムの利用目的に応じた課題の遂行という実験を行ったところ、異なる国のデータとの比較を行う際には、外国語の新聞を直接の比較対象とする必要性などが指摘された。この指摘を受け、機械翻訳システムと組み合わせることによりシステムを作成した。このシステムでは、ニュースなどの時事的なトピックに対する対訳辞書の不備を補うためのWikipediaを用いた対訳辞書の作成方法などの提案も行った。また、ピンポイントクラスタリングによるWebサイトの分析」の課題については、昨年度から継続して、フォーマルコンセプト(FCA)を用いた分枝限定法にもとづくトップN-FC探索手法の研究を行った。

本研究では、問題解決を目的とした文書作成支援型知識マネージメントシステム(Documentation MAnagementsystem for Problem Solving:DMaPS)の構築を目的とした研究を実施した。このシステムでは、問題解決の支援、文書と形式化された知識の蓄積、文書からの知識の獲得というループの実現を目指している。この目的に対し、平成17年度は、問題解決の支援を行うために、ユーザが持っている問題に関する記述と類似している文書知識を提示することにより、問題解決の支援を行うシステムを作成した。本システムに対し、あらかじめ手作業により作成した知識を埋め込んだ文書群を与えることにより、問題解決の支援が可能であることを確認した。平成18年度以降は、主に、一般的な文書から問題解決に役立つ知識を獲得するための方法論に注目して研究を遂行した。具体的には、トラブル事例に関する知識獲得を目指して、新聞記事などから、ユーザが直面している問題に関連する訴訟の記事などを検索し、その検索結果から、関係する利害関係者とその関係を抽出するシステムの構築を行った。本システムでは、少数の訓練事例にたいして、複数の基準を用いた機械学習システムを適用し、その結果を組み合わせることによって、人手で作成したパターンでは抽出することができなかった多くの利害関係者の情報を獲得することが確認できた。また、文書分類の研究では、特許を関連する物理法則によって分類する考え方を提案し、Web上に存在する様々な物理法則に関する文書の情報などを利用して、具体的な特許文書を分類する方法を提案した。ただ、これらで得た知識は、DMaPSで利用可能なレベルの知識での形式化が困難であったため、今後は、形式的な知識作成に関する検討を進める必要がある。

本研究では、検索意図を推定し、それをユーザにも理解しやすい形式で表現できる情報検索システムを提案する。ここでは、検索者が用いる検索語の抽象度に注目して、検索意図の推定を行う。しかし、ユーザは、検索意図を表現するのに適切な抽象度の概念を必ずしも用いない場合がある。そのため、検索意図に応じた適切な抽象度の概念を検索キーワードに用いると、ユーザにも理解しやすく効率的な検索キーワードになると考えられる。
そのため、本研究では、電子化辞書やシソーラスに記述されている概念階層構造を利用し、検索意図に応じて検索キーワードを適合的に汎化し、新たな検索式を作成する情報検索システムを提案する。ここで、適切な抽象度の汎化とは、検索キーワードが持つ正解判定の分別能力に関する情報を多く保存する汎化の事である。
本年度は、検索式における検索語と検索要求のミスマッチという観点から検索課題の持つ性質の分類を行うと共に、検索語拡張に与える影響を分析した。その結果、検索語と検索要求のミスマッチのタイプに応じて、検索語拡張に求められる機能も異なり、単一の検索語拡張手法では、検索性能を改善させる場合だけでなく、性能を悪化させる場合があることが確認された。よって、検索語拡張の洗練化を行うためには、検索語と検索要求のミスマッチに応じた検索語拡張の方法の提案と、ミスマッチのタイプの推定を行うことが必須であることを提案した。

In the research project, an algorithm for extracting common abstract event sequences, given two or more documents, is presented. In order to avoid combinatorial explosions in matching more than two documents, the algorithm consists of two phases.
The first phase is basically a text summarization system taking balances between the importance of sentences in each segment in a given document and the importance of sentences to connect several segments. The latter importance is used to extract contextual sentences involving contextual words. In order to separate the notion of importance into the two as in the above, we compute a chunk of core sentences in each segment by a clique finding algorithm, and then calculate the degree of latter importance of sentences from the chunk just in the way used in KeyGraph. Finally, the overall importance is determined by a scheme very similar to topic-sensitive PageRank. We have made some experiments for newspaper articles, and verified its effectiveness.
In the second phase, we use the summarized document obtained in the first phase as a kind of source document. The summarized document preserves the structure of the original document at more abstract level. Therefore, for each event in the source, it suffices to find a similar event in a given target document. This drastically reduces the computational complexity need to build correspondence between the two documents. As a result, several document set is now summarized from a viewpoint of the source document by means of analogy.

Research on design support by creative abduction

This project presents "Universal Abduction Studio" (UAS) that is a new approach to computational support for designers and discusses technologies to implement it. Although design support systems have been well developed for geometric and detail design stages, they are still unsuccessful in the conceptual design stage. In our opinion, the main difficulty comes from incomplete and insufficient understanding about design knowledge and its operations that play a crucial role in conceptual design. In contrast, however, recently thanks to development of the Internet technologies, more and more knowledge is accumulated and available electronically. It then becomes an interesting research question how to apply such an enormous amount of diverse knowledge to conceptual design. UAS is not intended to be an automated design system. UAS is an environment in which designers can manage and apply knowledge to arrive at new, creative design collaboratively with the system. UAS provides the designer with knowledge and reasoning functions, while the designer selects operations and evaluates design results iteratively. we show a novel knowledge representation to support creative design process. Our RDF-based representation consists of modules for knowledge repositories like predicate and object ontologies. A user can compose an individual model for knowledge by selecting and combining suitable elements in these knowledge repositories. This representation solves two characteristics observed in our case study analysis, ie., multiplicity of interpretation and variety of knowledge. The graph structure can generate multiple interpretations with minimum modification such as redirecting "if" and "then" links. Furthermore, since we separate metamodel and aspect-specific models, we can obtain various aspect-specific models from a single metamodel. The problem to handle with variety of knowledge is balance of expansivity and consistency. Since we provide categories of knowledge like object and predicate ontologies in order to clarify roles of knowledge, we can add easily new knowledge like domain-specific knowledge according to its roles without avoiding messy.

本年度は、この適合的汎化による検索拡張が、正解文書において補完関係にある検索語の発見を目指しているという点に注目し、適合的汎化による検索拡張の結果をBoolean式として表現する方法について検討を行った。さらに、実際にユーザが利用可能なインターフェースの作成を行った。また、文書中の語の役割を反映した抽象概念の提案手法についても検討を行った。これらの手法の有効性は、実際のユーザ実験によって検討する必要性がある。次年度以降は、ユーザ実験などを通して、本手法の有効性の検証と手法の洗練化を図っていきたいと考えている。

吉岡 真治, 大久保 好章, 原口 誠
本研究では、検索者にも理解しやすい概念階層の汎化という考え方を利用して、ユーザの検索意図を明示化すると共に、精度落ちを抑えた情報検索システムを提案している。この概念階層を利用する情報検索システムでは、汎化の対象としてどの様な語を選ぶのかという問題に加え、あらかじめ用意する辞書における概念階層の性質に結果が依存するという問題がある。
本年度は、汎化のための方法論として、適合文書群に共通する概念を利用する方法を検討した。学術論文のアブストラクトを用いたNTCIRや新聞記事を用いたIREXの2つの情報検索のテストコレクションを利用し提案手法のシステムの検索性能への影響を検討した。その結果、提案手法により検索性能が向上することが確認できた。
次に、辞書の性質を議論するために、昨年度までの研究で用いていたEDR電子化辞書に加え、日本語概念語彙体系という異なるタイプのシソーラスを用いた場合の影響に関する分析を行った。検索実験の結果、日本語概念語彙体系を用いた場合に、与えた適合文書へのオーバーフィットの度合いが高いことが確認された。これは、日本語概念語彙体系とEDRが持つ概念カテゴリーの粒度の違いによるものであると考えられる。日本語概念語彙体系とEDRが持つ概念カテゴリーの数を単純に比較すると、EDRは約50000個(専門用語辞書のものを含む)であり、日本語概念語彙体系は約3000である。よって、適合的汎化による情報検索システムで用いるシソーラスは、ある程度、粒度の細かい概念を扱うことができるシソーラスであることが望まれることが確認された。

設計対象モデルを用いた設計文書の体系的管理と再利用に関する研究

吉岡 真治
本研究では、設計問題に代表される問題解決の過程を問題を表現するためのモデルとそこで用いられた知識さらに、その際に記述された文書を組み合わせて保存することにより、設計文書の体系的管理と再利用を実現することを目的とした。その成果として、問題解決のための文書管理システムDMaPS(Documentation Management system for Problem Solving)を提案した。
このDMaPSでは、ひとつのサブ問題の問題解決の過程を単位として考えた文書知識を利用して、文書の管理と問題解決の支援を行う。この文書知識では、文書を単純なテキスト情報として保存するだけではなく、知識を適用する背景となる条件や形式的な知識を一階述語論理によって表現する、この二つの表現を組み合わせることにより、マニュアルなどの形式知とノウハウのように形式化が困難な情報を組み合わせて取り扱うことが可能となる。
本システムでは、この文書知識を用いることにより、ユーザの問題解決の支援を行う。具体的には、ユーザが直面している問題との一階述語論理による形式的表現に関する類似性とキーワードによる情報検索による類似性という異なる観点から知識の検索を行うことができ、より柔軟な知識の検索を実現する。また、検索された知識を取り込むことにより、問題解決の過程を説明するための文書が半自動的に作成でき、ユーザは個別事例に適応させる部分の記述に専念することができる。さらに、本システムでは、知識のバージョン管理の機構を取り込んでおり、各文書問題解決の際に利用した知識のバージョンをチェックすることにより、既存の設計文書をそのまま再利用してよいのか、再検討が必要なのかを調べることが可能になっている。
本研究では、建築構造物の基礎設計を例にとり、知識記述の実験を行い、体系的な知識整理が可能であることを示した。

一方、電子化辞書やシソーラスでは、一般的な概念階層が記述されているために、多段階の階層を用いた汎化を行った際に、一度に大量の語を代表する概念に汎化されてしまう問題がある。例えば、「ビデオ」と「DVD」を汎化した概念として「映像装置」という概念を考えたときに、8mmカメラは含むことは、検索意図と必ずしも一致しないと考えられる。そのため、ユーザが持つ細かな検索意図を適切に表現するために、検索目的に応じた適切な抽象概念を設定し、概念階層を再構築することが必要である。
本年度は、概念の適切な抽象化のための指標として、キーワードと正解文書の相互情報量に基づく関連性の指標を利用し、情報検索システムを構築した。本システムは、5件の正解文書を与えることにより、検索語の汎化を行い、検索者の意図が理解しやすい検索式が作成可能である。また、この検索式による検索は、他の検索システムと比較して十分な検索精度を持っていることを確認した。

TAKEDA Hideaki, TAKEUCHI Koichi, UENO Atsushi, NISHIDA Toyoaki
In this research, we proposed concept "knowledge as media" to realize knowledge lifecycle for communication support on the network. In the traditional view of artificial intelligence, Knowledge exists within agents such as human and computer programs. On the contrary, we regard knowledge exists among agents, i. e., knowledge is media which enables communication among agents. Under this view, we investigated knowledge from the abstract way to the practical one. Ontology is the most abstract form of knowledge, knowledge for community and knowledge for environments are intermediate, and the embodied knowledge is the most practical one. We have three major results. One is community-support system called TelMeA in which interface agents as participants can form a field of communication. We tested this system by the psychological experiment and showed that using interface agents like this system is effective for communication. The second result is a system to capture personal knowledge. The system called MindHeap can gather knowledge through WWWW browsing. If a user can pick up sentences in WWWW, the system memorizes the sentences and their contexts. The sentences are connected to each other through their contexts in this system. The user can retrieve related memorized sentences automatically and even summarize WWW pages based on memorized information. The third result is embodiment-based learning, in which embodiment knowledge is captured through actions. The agent can learn how its body is by moving around and sensing the environment.

In recent years, research networks have extremely diversified, not only in developed coutries but also in newly developing contries and region, including mid and east europe, mid and south america, africa and asian coutries. As the result, international coordination among research networks is of important to establish international communication links. The CCIRN (Coordination Committee for Intercontinental Research Networks) plays primary role of such coordination. In addition to this, need for braodband communiation links is emphasized in order ato stimulate higher end researches. In this context, the CCIRN is now discussing how to interwork such broadband communication links and networks.
United States had lauched new interconnecting point among broadband networks in Chikago, IL., which is called STAR-TAP (Science, Technology and Research, Transit Access Point). Investigators joined to the study have made international cooperation activities during three years, and finally made success to interconnected japanese boradbnad network (SINET) to STAR-TAP in October, 1997.
European Commuinity has also put in operation of braodband research network (TEM-34). SINET has been cooperating to european resarch networks for three years, and consequently SINET has changed its connection point to TEM-34 PoP (Point of Presence) to London, UK.Circuit to London will be in operation from early April, 1998. That is second result of the study.
Beside the actual interconnection, investigators have been contributing international standardization at IETF on ATM based networking. Several proposals which are now available as Internet Drafts, including ATM address resolution scheme, ATM inteconnection control information and high-performance protocol sepcifications, are proposed from the study.
These activities are evaluated as future basis for international connection of research networks.
