The subject heading is an elaborate access tool for subject browsing and searching in information retrieval environment. The purpose of this study is to suggest the applicable facets to subject headings in Korea. First, the concepts of subject and the definitions of facets were investigated in the literature review. Second, six cases including OCLC's FAST, PRECIS, "Thesaurus construction and use", CC $7^{th}$ edition, BC $2^{nd}$ Edition, and UDC $3^{rd}$ Edition were analyzed to focus on configuration of facets as case studies. Based on the results, twenty-two facets were proposed including Topical, Event, Geography, Chronology, Personal and Corporate Name, Title, Form, Genre, Language, and Person facets as 11 top facets. Also, Topical-Thing/Entity and Topical-Action/Status, Part, Kind, Property, Whole, Material, Patient, Product, By-Product and Agent facets as sub-facets of Topical facet.

To search based on the functional classification or provenance is not easy for users, and the key word-based information retrieval presents only simple words matching with the title of the records. The Presidential Archive of Korea developed a subject classification scheme to improve the convenience of searching for various records and came up with a subject thesaurus based on the scheme that utilizes the terms appearing on the title of the records and the terms used by the users who searched the portal or requested information disclosure. This research presents the development process of subject thesaurus. It also presents the utilization methods for records management work and services.

본 연구에서는 기존의 분석합성형 분류체계(BC2)로부터 개념과 관계를 추출하여 작성한 자모순 시소러스에 패싯도구를 삽입하여 용어의 개념과 관계를 정확하게 이해할 수 있도록 제시하는데 그 목적이 있다. 그리고, 이러한 과정을 통해 기존의 분류체계나 시소러스가 지니고 있는 한계를 개선하고자 한다.

The goal of this research is to develop a Remote Medical Examination System on Oriental Medicine on the very high sped information communication network. We developed a remote medical examination system based on the sample examination data of 10 patients and develop the information of search database based on contents. We analyzed the sample data and the requirements of patients, doctors, and nurses. By the analyzed result, we designed and constructed a prototype are as follow: the multimedia ORDBMS server system, network interface technology, internal/external database schema design, oriental medicine expert knowledge base design, inter-data search algorithm design and thesaurus.

In this paper we constructed semantic net that can efficiently conform retrieval and reuse of object-oriented source code. In order that initial relevance of semantic net was constructed using thesaurus to represent concept of object-oriented inheritance between each node. Also we made up for the weak points in spreading activation method that use to activate node and line of semantic net and to impulse activation value. Therefore we proposed the method to enhance retrieval time and to keep the quality of spreading activation.

In this paper, the automatic keyword classification which is one of the automatic construction methods of retrieval thesaurus is experimented to the Korean language on the basis that the use of retrieval thesaurus would increase the efficiency of information retrieval in the natural language retrieval system searching machine-readable data base. Furthermore, this paper proposes the application methods. In this experiment, the automatic keyword classification was based on the assumption that semantic relationships between terms can be found out by the statistical patterns of terms occurring in a text.

사람의 언어를 이해하는 자연언어처리 시스템을 개발하기 위해서는 의미처리를 위한 지식 베이스(knowledge base)가 필요하다. 지금까지 사람이 가진 지식 베이스를 컴퓨터에 도입하려는 많은 노력을 기울이고 있고 그 결과물로 온톨로지(ontology)와 시소러스(thesaurus)가 만들어지고 있다. 외국에서는 지식 베이스의 중요성을 알고 많은 연구를 수행하고 있으며 그 대표적인 사례들에는 Roget's Thesaurus, WordNet, EDR 개념사전, CYC, Euro WordNet 등이 있다. 이 중에서 가장 대표적이며 많은 활용을 보이는 것이 Princeton 대학의 WordNet이다. WordNet은 인간의 어휘지식에 대한 심리 언어학적인 연구의 결과물로써 심리학자와 언어학자들에 의해 10여 년 동안 구축되고 있는 영어에 대한 어휘데이터베이스이다. 본 논문에서는 WordNet을 기반으로 명사에 대해서 영한사전과 국어사전을 이용하여 구축한 한국어 워드넷을 소개하구 구축시 고려한 기본지침을 소개하도록 하겠다.

To improve the efficiency of business, it is important to standardize the meaning of terminology. And then, terminology dictionaries have been actively being built and used in various fields. In defense area, the publication of defense terminology dictionary is useful for information exchange of each army and distribution of standardized terminology. Defense agency for technology and quality(DTaQ) publishes terminology dictionary of defense science and technology on a three-year cycle. DTaQ tries to standardize the construction process of terminology dictionary and improve service efficiency by using terminology dictionary in defense area. This proposed method is based on the result of previous study about standardization of terminology dictionary. We suggest the practical steps including terminology dictionary constructing process, composition and role of organization, definition of headword, selection of target documents to be extracted terminology candidate, terminology extraction, generation of terminology candidate group, workbench registration, construction and validation of terminology dictionary. Thesaurus and workbench are developed to use and support terminology dictionary effectively.

The purpose of the study is to construct a History Ontology Model for historical person to analyse issues of Korean History Thesaurus and interview history specialists who are use information systems in National Institute of Korean History. This study verifies the difference between both descriptions through comparative analysis of term concept in Korean History Thesaurus and mind-map written by history major. Based on this, we build history ontology model to meet users' information needs and adapt to information retrieval system. First, to organize unique features of history, we define class and attribute and then enlisted considerations for instance input. The study suggests a possibility of new service through combination multiple features using concept extension that is a strength of ontology.
