本稿では，主成分分析を利用し，耳画像に基づいて個人認識を行う方式を提案する．近年，顔画像に基づく個人認識が広く研究されているが，藤画像は加齢や表情，体調の変化などに影響されるため，同一頗画像を長期間利用することは難しい．これに村し，耳は16歳前後から安定期に入り，形状が変化しにくいという利点がある．本方式は，入力画像に村し，輝度の正規化およびモザイク処理を施した後，主成分分析により，入力データの次元圧縮を行う．学習時には，1枚の入力画像に村して平行移動・回転を行った画像を登録することで，入力画像の位置ずれに対処する．実験により，提案する方式は110人の耳画像を99．7％の精度で認識できることを確認した．
We propose an individual recognition system using eigenear images. Although face images change owing to changes of emotion, growth, expressions, infirmity, and so on, ear images cannot be affected by them. Our system utilizes principal component analysis for dimensionality reduction, and Mahalanobis' Distance for individual recognition. Experimental results show that our system can recognize individuals with the high recognition rate 99.7% approximately the same rate of an existing method based on Genetic Algorithm(GA) in shorter time than that of the GA-based method.
本研究では，用語体系の再利用性の向上と効率的な提供を目指してWebサービス（Web Services）の枠組みを利用した用語体系提供システムを碍築した．さらに，この用語体系提供Webサービスをバックエンドとする2つの応用システムを構築し，それによって，その適用可能性を示した．2つの応用システムは，用語体系のブラウジングシステムと，Googleによる検察Webサービスと連携するシステムである．用語体系提供Webサービスは，それぞれ一つのサービスが一つの用語体系に対応することとし，見出し語検索と見出し語が持つ樽造の取得を行う2つのインタフエースをもつ．用語体系をWebサービスの枠組みに基づいて提供することにより，アクセス方式が統一でさ，用語体系を提供する側，利用する側が相互に分散的に利用することが可能になった．
We developed a providing service system of a terminological system, using a framework of Web Services, since we aims at improvement in the reusability and at efferent providing of a terminological system. The following two applications are successfully developed with the providing service system as a back-end service; one is a browsing system of several terminological systems and the other is a cooperating system with Web service of Google: search engine of Web pages. We used EDR technical term dictionary and a hierarchical structure data by Open Directory Project, as typical terminological systems. One service corresponds to one terminological system in our implementation, and has two interfaces; one searches word entries and the other acquires the structure of the entry. Various access methods to a terminological system are integrated to the access method with the framework of Web Service. Then, the method makes it possible for a user and a provider to access a terminological system in distributed way.
昨年若手の会員有志が学会事務局で懇談会を開催し，学会の有りようについて議論し，その模様が出席メンバーによって学会のホームページに発表された．これについて筆者は多大の感銘を受けた．感銘の第1は若手から学会の事業その他について自発的な意見発表があったことである．このようなことは，学会として初めてであろう．第2はこのようにホームページのような形で会員の意見を集約することを今後努力すべきだということである．これはどこでも今盛んにしていることであるけれども，我々もその線の努力をすべきだと思った次第である．そこで，後者の線に沿って，一会員として，学会活動展開の方策の私見をここで提言し，同時にその反響をホームページ上ででも討議出来たらと思い，先ずこのに誌上に提言させて頂くことにした．
Abstract In Japan, there has recently been an increasing interest in health, home care and welfare, as we enter into a society occupied by more and more elderly people and a smaller number of younger citizens. The Japanese government and the administrative divisions of Japan, including Tokyo, Hokkaido, Osaka, Kyoto and all the prefectures, have been adopting many kinds of health and welfare policies. As one such policy, the Ministry of Health, Labor and Welfare designated an instrument for blind people and elderly people as a "daily life tool" in April 2003. This instrument translates information printed on paper to voice reading. The Ministry's policy and the associated budget will enable blind people to purchase the instrument with very little cost. Our company developed this instrument, called "SPEECHIO." as well as the new software that converts text to two-dimensional symbol named "SP-CODE." The SPEECHIO reads SP-CODE and changes text into voice reading automatically. We believe thig new barrier-free communication system will greatly help blind people and old-aged people who have difficulties in reading small prints. In this article, I describe this system and our ongoing and future ,activities with the system.
Abstracts: The rapid advances in digital technologies and networks have radically altered and improved the ways that data can be produced and used in science. The public domain information is defined as sources and types of data and information whose uses are not restricted by intellectual property or other statutory regimes and that are accordingly available to the public for use without authorization or restriction. It is increasing the pressure between the need of science for the free flows of data and information, and the considerations of the intellectual property rights with regards to the same data and information under the digital network environment. It is discussed in the case of the Global Biodiversity Information as the one of academic data and databases how to implicate the intellectual property rights on the databases. The EC Database Directive 1996 is created by a two-tier structure of intellectual property protection for original databases through copyright, and a new sui generis right for other unoriginal databases. In the United States, the bill named the Database and Collections of Information Misappropriation Act of 2003 (H.R.3261) is now in the process of legislation on the Congress. Where access to information is at issue, it would be necessary to introduce the new model of database rights as balanced with the free flows of academic data and databases in Japan.
Classification of research fields for the Grants-in-Aid application has been changed a great deal since 2003 fiscal year. Changes in the interdisciplinary and new area are marked especially. It is interesting to find out where the usual research fields are moved to in the new classification. In this study, we focus on Information Science fields which were extended from the three to 11 research fields, and investigate which new research fields have strong relationship with and how they are located in the usual three Information Science fields by making use of those continuing adoption research started before 2002 and by analyzing keywords of research themes as well.
本研究は情報資源共有における「メタデータハーベステイングプロトコル（Open Archives InitiativeProtocol for Metadata Harvesting：OAI−PMH）」の適用とその可能性について論じる。OAI−PMHは分散化が進む学術分野における情報資源のメタデータをシステム間で共有するための技術基盤である。同プロトコルは相互運用性の補完を意図したフレームワークであり、メタデータを共有することにより相互の情報資源に対するアクセシビリティを確保する。本研究では、実際にOAI・PMHを用いてネットワーク上に公開された複数の情報資源のメタデータを収集し、横断検索するシステムを構築することで、情報資源共有への応用可能性について考察した。
This paper describes application of Open Archives Initiative Protocol for Metadata Harvesting: OAI-PMH to information resource sharing. OAI-PMH provides an application-independent interoperability framework to share metadata among information service systems. OAI-PMH allows users to have seamless access to the information resource on the Internet. In this study, an integrated information retrieval system of metadata which was harvested from other systems based on OAI-PMH was constructed.
In recent years, an information technology has been progressed. And our country is establishing to a highly information-oriented society. Then, the support system to information practical use is aimed to build for personal-use. However, in a meaning of making good use of material information, there are still many inadequate systems. Then, this paper considers the development technique and the state of the support system which surround material information by making into an example the database application system which supports archaeological data research.
Abstract: There exist two types of e-Iearning systems. One of them aims to improve the education efficiency. Distance lecture system and WBT(Web Based Training) belong to this type. In these systems, interaction between educators and learners become lower than in the conventional classroom teaching. Therefore, these systems cannot improve the education qualities. The other aims to improve the education qualities. The e-learning systems in this type, which are newly developed, notify the educators of the learners' conditions in real-time and support educators' activities. One of these systems automatically lectures using WBT and notifies the educators of the stalled learners and their learning data (exercise answers and questions). Depend on these data, educators concentrate on the education to each stalled learner. Another system is used for the lecture for large number of learners. This system notifies an educator of the learners exercise advance in real-time. Depend on the data, the educator judges if he gives advises to the learners and if he explains the next item. The e-learning systems have another merit that educators can improve the education methods by analyzing the accumulated education log. As this field is on the way of development, future study is anticipated.
A method in an innovation and effects caused by it are described in patent document. We regard the method-caused effect as casual relationship and consider it available to construct creativity support system, therefore we have extracted some casual relationships. In the future, we try integrating hirearchial relationships into casual relationships to construct function of analogical reasoning. Therefore, in this work, we extracted hierachical relationships from patent documents, especially selecting medical field as extracting target.
Abstract: Free term searches is one of the most effective ways to search text data. However, it is difficult to search fore specialized texts such as historical official records, in which there are many specialized terms different from currently used. It is also difficult to compile a thesarus, which covers all diversified historical terms. This paper proposes one solution using a speacialized dictionary compiled for the Japan Center for Asian Historical Records.
抄録：1990年代以降、複雑なデータ構造をもつ様々な対象に対する情報視覚化の研究が盛んに行われるようになった。EDR電子辞書やNTT日本語語彙体系のような階層構造を有する大規模用語知識ベースを対象として、単一円錐モデルに基づく仮想3次元表示プログラムをJAVA3Dを用いて実装した。さらに表示用語総数に対する実行時間の計測を行った。描画対象オブジェクトの総数をnとすると、描画処理そのものは計測結果からO(n3）となることが判明した。プログラム言語の制約、仮想3次元描画対象としての用語知識ベースの特性から、高速化の可能性について議論した。
Abstract This paper shows an example of converting XML from RDB data technique as archeological information. In addition. it shows the technique of developing Web-DB application that used XML as an example of application of the XML data.
本稿はUNIXワークステーションのアカウンティング情報を用いて利用者のネットワーク構造を抽出する手法について述べ，得られた大学生計算機利用者の人間関係の特性について考察する．情報システムというように「人」が主役の場では人の関係が重要である．例えば，初対面の人と会った場合には，自分とその人とのつながりや，趣味，共通の知人などが分かれば，コミュニケーションがよりスムーズに進むと考えられる．このように情報システム利用者の社会ネットワークは非常に重要な情報のひとつであると考えられるが，これまで情報支援の研究において着目されることは少なかった．これは利用者のネットワーク構造を情報システムが獲得することが困難であるめであると考えられる．本稿の手法を用いた結果、大学生の人間関係は任意の二者間の平均経路長が２．95人であるスモールワールドネットワークの特徴を持つことがわかった。
In this paper, we propose to extract the socail network of participants from the information system using their accounting records. We discuss the social network feature. In an enviroment of information system, it is desirable to provide a user with information depending on a user's situation, such as time, location, user behavior, and social context. Since such information was difficult to gain from system, it was rate to be used. We also discuss the analysis of social network in the campus computer system.
Abstract The availability of complete genomic sequence data allows one to develop new methods of reconstructing phylogenetic trees. A simple method of reconstructing branching orders based on gene transposition (or lateral transfer) is presented. It is shown that specific gene arrangements on four different genomes could determine a branching order. A computer search for such gene arrangements was carried out against gene order data of the completely sequenced Gram-positive bacteria, and the results will be discussed.
Abstract. We developed a remote aged care system for Hanazono village which is one of the typical underpopulated villages in Japan. In many of such depopulated villages, there is the problem that the number of visiting nurses who provide aged care services is not enough. As a result, visiting nurses can visit aged people not so often (it might be once a week or so), and hence aged people is easy to lose their health. To improve this situation, our system helps visiting nurses get hold of the health condition of aged people by showing the information of their daily health condition which is input everyday by aged people at their own houses. Here, to make a easy input operation even for aged people, we use L-mode terminals at each house and design easy-to-operate Web pages which are accessed by the terminal. We further performed a test operation of our system in Hanazono village and confirmed the effectiveness of our system.
Abstract We have presented the concept and planning of the project ICJS: International Collaboration for Japanese literary Studies, in the 10th annual conference of JSIK held on 2002 in Tokyo. The project has been started from 2001 as the five-years program, founded by the Grant-in-Aid Scientific Research (S). In this presentation we will generally report on the interim result for three years, and particularly focus on the new collaboration system through feasibility experiments. We are now in feasibility studies, an example of simultaneous searching using a Dublin Core meta-database system is shown as follows. The six databases are currently connected to the collaboration system at the NIJL: the microfilm resource directory (a catalog of the microfilm held at the Institute), the old Japanese book directory (a catalog of the manuscripts held at the Institute), the thesis directory (a directory of theses related to Japanese literary research), the historical material location directory (a directory of the places historical resources are held at the Institute), the image database (an image database of materials held at the Institute), and the moving picture database (performing arts video data). Then, we have been making arrangements expand and develop enlarge the system to Inter-university or Institute common collaboration system. For example, we will construct among the Institute such as National Museum of Japanese History, International Research Center for Japanese Studies, National Museum of Ethnology, The Historiographical Institute University of Tokyo, Osaka City University and Kyoto University. At the next stage we will be connecting to Italy, France, U.K. U.S., etc.
