On the Role of Levels in Concept Hierarchies in the Descriptions of Formation Patterns of Complex Terms

KAGEURA kyo
学術情報センター

In this paper the author examines a possible contribution of the explicit introduction of 'levels' in concept hierarchies in the description of formations of complex terms. First, some semantic or conceptual analyses of complex words are reviewed, showing that the semantic or conceptual categories used in these studies implicitly presuppose certain levels in semantic or concept hierarchies but they do not need to introduce 'levels'. The importance of levels in concept hierarchies in the description of term formations are then considered, proposing a different description viewpoint of term formation which is valid for terms but not necessarily ordinary words. Finally how term formation patterns are described is roughly sketched.

Extraction of Hierarchical and Associative Relationships in The Standard Technical Terms

The importmice and the necessity of the organization of information have been increasingly recognized. It is reasonable that organization of terms as units for expressing concepts is an important method for organization of information. The method of SS-KWIC extracting hierarchical relationships and associative relationships automatically based on the coining rules in terms is discovered in our reseach. The principle and realization of method of SS-KWIC are shown, and a example of the experiment results is given in this paper. The experimental results that detailed hierarchys and rich associative relationships are obtained, proved reliability and practicality of the method.

Stractural Analysis of Japanese Medical Terms

Describing medical data or knowledge, natural language representation plays quite important roles. In machine processing of information described in natural language, concept dictionaries that describe meaning and relationship of various terms are very important. Because most of medical terms, like terms in other specialized fields, can be regarded as composite terms, compiling a medical concept dictionary, it seems effective to prepare elementary terms and composing rules. In this paper, the authors, from the viewpoint of elementary terms and composing rules, discuss about inferring conceptual category of medical terms in a large scale dictionary. Discussions in this paper will concentrate to terms that represents various site, organ or tissues in human bodies.

Creating a Vocabulary Index for Genji Monogatari Taisei

H.Ueda, etc
統計数理研究所

Indexes of the words in Japanese literary classics are generally arranged in a-i-u-e-o order, under which headings the words are given with various prefixes, suffixes, inflections, and so forth. Thereafter the volume, page, and line numbers of each entry are given. Very occasionally, particles, auxiliary verbs, and other associated words are also listed. Such indexes are useful in defining where and in what context each word of a classic is used. However, if you want to know whether some particular word is always used in the same context, you must check every page on which it appeares and note with what other words it appears in conjunction. This can become a very cumbersome process for words frequently used. The current study aimed at creating a software program that could list up words (in boldface type) in a-i-u-e-o order, together with five to six preceding and the same number of following words that revealed the context. This was achieved using our previously completed full-text database of Genji Monogatari Taisei in which all words had been identified by parts of speech.

法帖に含まれる情報、および法帖について史上研究されてきた詳しい情報をマルチメディア・データベース化することを最終的な目標として、そこに含まれている情報の種類と内容を検討した。ことに、法帖が長い歴史をもち、また繰り返し複製されたものであることから生ずる情報の多重性に注目し、これを反映するために、以前に提出したER モデルを修正した。

Classification and Identification of Yeasts

Hideaki SUGAWARA, Satoru MIYAZAKI
理化学研究所

Microorganisms have played an important role in the chain of energy and chemical conversion on the planet and increase the awareness of the public in the age of the global environment of the planet. Classification and identification of microorganisms have been our basic intellectual activities and increase the necessity in the age of biodiversity. Therefore we developed an information-base which supports them. Yeasts were chosen as a model microorgnism in the development. The information-base is an interactive system in which users are able to infer a taxonomic structure of yeasts and assignment of newly found strain to a taxonomic group.

Distributed Database for Materials(Data-Free-Way system)

M.Fujita,etc
金属材料技術研究所

Distributed database system named "Data-Free-Way" for advanced nuclear materials has been developed by National Research Institute for Metals (NRIM), Japan Atomic Energy Research Institute (JAERI) and Power Reactor and Nuclear Fuel Development Corporation (PNC) under cooperation agreement between these three organizations. In this paper, feature and functions of the system including input data are described together with method to share database among the three organizations as well as example of the easy accessible search of material properties. Results of analysis of tensile properties data on type 316 stainless steel collected by the different organizations and stored in the present system are also introduced as an example of attractive utilization of the system.

Information-Base Systems for Nonlinear Optical Materials

Norihiko Uda, Yuzuru FujiwaraO
筑波大学

Research and development of material design require advanced systems which have sophisticated functions such as analogical reasoning, inductive inference, abductive inference as well as retrieval and deductive inference. This paper describes Information-Base Systems with Self Organizing Receptor Interconnections(IBS/SORITES) for nonlinear optical materials design. The systems store full-text, and structuralized information including semantic relationships which are extracted from fulll-text automatically, and have capabilities of navigation in the conceptual space as well as in the logical space and analogical reasoning in addition to retrieval and browsing.

On the appreciation of the bibliographical information

Bibliography generally means The listing of books, including the list of auther's works, the list of references to show the sources used by the auther, the collected contents of the magazines, and, in the broad sense, the personal history and the chronology and so on. The study of modern bibliography has, however, made so little progress that such a classification is ambiguous. This stagnation of the bibliography partly causes the general low understanding of it. It seems evident that the bibliography is most important in the study of literature, but in fact it is valued lowly in spite of its importance. The reason is mainly that it is not in the essencial parts of literature but in the marginal parts. In addition, it is owing to the difficulty of appreciation of it. Though it must be appreciated in the peculiar viewpoint which is different from the viewpoint of the study of literature, it is not yet made a trial. There are three conditions of the bibliography which are the inclusiveness, the accuracy and the usefulness. The word of usefulness is not necessarily proper. It may be defined as to be easy to use or to be used by anybody in other words. In this point, you may replace it with the commonality. You can add the promptness and the continuity to these three conditions above.

A Study on Information Analysis of Historical Materials

YAEGASI Junki
歴史民俗博物館

In the recent year , activity of organizing on academical information resources have been actively developping in the many historical branches in japan. But , the historical materials have been exessively variated and many of them have been exited as partial and probable. Information characters of them are nondeterministical and nonstructual. Designs and Creations of data from these materials are very troublesomes. So, for forming and adjusting these ploblems to develop the database and data from these historical materials, we have been experimenting the methodology of analysis and organi2ation of information , taking as some examples of historical materials. This paper- describes as followings.
