The purpose of this study is to classify theological terms using facets and form foundation to build a theological thesaurus The terms was chosen in a English theological dictionary and the number of them are 1,031 but eventually, 984 terms were classified. The facets which classify the terms are 7 fundamentals and 14 sub-facets. Analysing the result of classification, abstract terms are much more than physical terms. They are 70% of the whole. Decimal classification to classify documents comes to dead end. therefore I think the research to classify terms of a specific subject as theology must be active. Furthermore, It is necessary to have knowledge about a specific subject to organize information in a specific subject.

The purpose of this study is to analyze and systematize the semantic relationships in knowledge organization systems(KOS) . For this purpose, Classification systems, thesaurus, subject headings, semantic networks, ontology, databases were analyzed in terms of the semantic relationships between terms. Also, various kinds of the terminological relationships not only in the current KOS but in the theoretical researches were collected and analyzed. In addition, six proposals were suggested for the organized system of the terminological relationships for the future uses.

The purpose of this study is to design metadata model for describing different kinds of concepts, properties, and semantic relationships of result materials of researches. We examine our metadata model to evaluate correctness and efficiency of the model through contents analysis of a constructed database. From the results of examination, we suggest more effective structure of metadata schema. Domain ontology could constructed by the enlarged thesaurus in order to overcome the limitation of the keyword search, therefore we design a philosophy and religion ontology based on subject classification to improve information retrieval and implement it using XML/Topic Maps to improve retrieval functionality of our database.

The purpose of this study is to develop the classification scheme in subject-based directory search engine for educational research information on the web. Five classification systems. Yahoo Korea, Argus Clearinghouse, DDC, ERIC thesaurus and KEDI thesaurus were measured in terms of coverage of subject fields, system logic, accuracy of terminology and efficiency of searching. For the design of Classification Scheme, this study considered the content of subject areas, features of information resources and efficiency based on users. Finally, the Classification Scheme was established in terms of 16 main divisions and 47 sub-divisions in educational research information.

Subcategorization, defining dependency relation between predicates and their complements, is an important source of knowledge for resolving syntactic and semantic ambiguities arising in analyzing sentences. This paper describes a Korean subcategorization dictionary, particularly annotated with semantic roles of complements coupled with thesaural semantic hierarchy as well as syntactic dependencies. For annotating roles, we defined 25 semantic roles associated with surface case markers that can be used to derive semantic structures directly from syntactic ones. In addition, we used more than 120,000 entries of thesaurus to specify concept markers of noun complements, and also used 47 and 17 predicate patterns for verbs and adjectives, respectively, to express dependency relation between predicates and their complements. Using a full-fledged thesaurus for specifying concept markers makes it possible to build an effective selectional restriction mechanism coupled with the subcategorization dictionary, and using the standard predicate patterns for specifying dependency relations makes it possible to avoid inconsistency in the results and to reduce the costs for constructing the dictionary. On the bases of these, we built a Korean subcategorization dictionary for frequently used 13,000 predicates found in corpora with the aid of a tool specially designed to support this task. An experimental result shows that this dictionary can provide 72.7% of predicates in corpora with appropriate subcategorization information.

본 논문은 시소러스의 구축에있어 시간, 비용, 노력의 최소화를 위해 외국 시소러스를 번역하는 방법이 언어, 제도, 사고방식, 문화 등의 이유로 어떤 문제점이 발생하는지를 고찰해 보고자 한다. 연구 대상으로 ERIC 시소러스를 번역하여 구축한 [KEDI 교육 시소러스]와 [ERIC 시소러스(7판)]를 선정하여 비교 분석하였다. 번역에 의존하는 한글시소러스 구축 방법은 권장할만한 방법이 되지못하며, 단지 우리말 시소러스 구축을위한 Discriptor를 추출하는 수단 이상을 기대하기란 어려우리라 여겨진다.

We employed a hierarchical document classification method to classify a massive collection of electronic medical records(EMR) written in both Korean and English. Our experimental system has been learned from 5,000 records of EMR text data and predicted a newly given set of EMR text data over 68% correctly. We expect the accuracy rate can be improved greatly provided a dictionary of medical terms or a suitable medical thesaurus. The classification system might play a key role in some clinical decision support systems and various interpretation systems for clinical data.

정보 검색 시스템은 사용자의 질의어를 용어들과 용어들 사이의 관계 집합으로 구성된 일종의 용어사전인 시소러스를 이용하여 문헌에 대한 색인과 검색을 정확하고 통제된 용어 형태로 바꾸어 색인과 검색 작업의 효율을 높인다. 클라이언트/서버 환경에서 시소러스를 이용하여 정보 검색 속도의 증가를 기대할 수 있다. 분산된 시소러스는 프로파일 정보를 가지고 운영되며 전문적 시소러스로 만들어진다. 본 논문에서 제안한 시소러스 작업 모형을 시뮬레이션 한 결과를 비교, 분석하고 클라이언트/서버 환경에서 효율적인 시소러스의 여할 및 작업 형태에 대해 제안한다.

우리나라에도 여러 가지 분야별 시소러스가 연구되고 있으나 여러 분야를 망라하는 대규모 한글매크로시소러스는 아직 없다고 보아야 할 것이다. 또한 분야별 시소러스를 통합하여 매크로시소러스를 구축하는 것은 거의 불가능하며, 통합할 만큼의 분야별 한글시소러스도 없다. 본 연구에서는 처음부터 매크로시소러스 구축을 위하여 개발한 범용시소러스 관리시스템의 내용과 이 시스템을 이용하여 전 분야를 대상으로 개발하고 있는 한글 매크로시소러스의 개발현황에 대하여 논하고자 한다.
