For the construction of thesaurus, a thesaurus management system is needed which can process dynamic variations fast and exactly such as input. correction and deletion of words, and definition of new relationship between words. In this paper, I developed a thesaurus management system based on the object-oriented technique and GUI(graphic user interface) screen, and to enhance the effectiveness of information retrieval. I put emphasis on the expansion of synonym, English and Korean words containing the same concept.

This paper reports an effort to construct a grand-scale Korean thesaurus that can be used for enhancing retrieval performance in various fields. This thesaurus is currently being used for indexing and retrieving purpose and new terms are being added to it. As the new demands on retrieval performance increase in Korea, developing a grand-scale ontology appears to be necessary so a project is undertaken to transfer the current thesaurus into an ontology system. The paper describes how the thesaurus is constructed and prepared to be the base for an ontology system.

The Matter of vmbulary control for newspaper database has been studied for a long time. These efforts hadn't made any good achievements until JOINS Thesaurus system developed. The purpx of this paper is to introduce JOINS Thesaurus whch the Jcong-ang Daily News has developed for the first time in Korea. In addtion to that, thls study is corn- the efficiency of Auto-Indexing system with postcontrolled indexlng system for newspaper database on thesaurus.

The purpose of this study is to examine the establishment and development of Daesoon Thought Thesaurus. Specifically, this study examined the matters to be considered in the stage of Thesauri planning according to the Thesauri Construction process : presents the methods and standards of Thesauri Construction according to processes such as identification of the indexing policy, establishment of Thesauri system, collection of vocabulary, selection of preferred term, clustering of the terms, establishment of term relationships, overall adjustment, Thesauri test, proofreading by professional display, maintenance and updating. Since religion information is unique or totally different from the information in other areas, it is most important to construct the Thesauri suitable for system after carefully recognizing the concept of religion terms.

As the role of a library has changed to the integrated management system of knowledge, the library needs new information retrieval tools. The purpose of this study is to propose a method and principle of the Korean-English semantic thesaurus construction for a knowledge management system. The method and principle is as follows; 1) in collecting terminology, I included not only internal documents but external documents on the web as a source for the descriptors extraction. 2) conceptual descriptors are more needed than semantic ones. I also proposed the necessity of the authority files for complement. 3) I proposed the appropriate scale of the descriptors to be 15,000 in a thesaurus. And 4) I proposed a hybrid method that used both a manual and an automatic process in establishing the relationship.

The purpose of this study is to develop a thesaurus for women's oral history in modern Korea. Literature review and case studies for four thesauri were performed for this study with which a thesaurus was built based upon the index terms in oral history records. The process of developing the thesaurus consisted of five steps. First, there are 1,784 index terms from the oral history records by 53 modern Korean women were extracted and analyzed. Second, possible terms for the thesaurus were selected through regular meetings with experts in the fields of information organization and women's oral history. Third, relationships between terms were defined by focusing on equivalence, hierarchy, and association. Fourth, after developing a Web-based thesaurus management system, terms and relationships were input to the system. Fifth, terms and relationships were again reviewed by experts from the relevant fields. As a result, the thesaurus comprise of 1,076 terms and those terms were classified to 39 broad subject areas, including proper nouns, such as geographic names, places, person's names, corporate names, and others, and it will be expanded with more oral history records from other people during the same period.

We present development results for a Hangul thesaurus which was provided to improve performance of the intelligent information retrieval system. The important stages and methods in the process of term acquisition, classification, creation of the consistency-effectiveness relationship using HiTEL menu and text of dictionary are described. To cany out our study we have built a thesaurus management system and also describe its utility functions.

In this study, the experiment was made to transform the relationship among terms in a thesaurus to ontology language as search tools for multilingual text. As a result, the equivalent relationship in the thesaurus can be expressed by different ways in the ontology, such as equivalentClass, equivalentProperty, sameAS, and so on. On the other hand, the associative relationship can be represented by ObjectProperty, DatatypeProperty, and inverseOf. For this test, first of all, the descriptors assigned by AAT and the descriptors from bilingual thesaurus by ICCD were translated into Korean. Then, the facet was used for conceptual equivalence among terms from different languages. The result of the study showed that using rdf:Property in ontology was the most effective way of transforming multilingual thesaurus into ontology.

This paper aims to offer a solution based on semantic document classification to improve e-Government utilization and efficiency for people using their own information retrieval system and linguistic expression Generally, semantic document classification method is an approach that classifies documents based on the diverse relationships between keywords in a document without fully describing hierarchial concepts between keywords. Our approach considers the deep meanings within the context of the document and radically enhances the information retrieval performance. Concept Weight Document Classification(CoWDC) method, which goes beyond using exist ing keyword and simple thesaurus/ontology methods by fully considering the concept hierarchy of various concepts is proposed, experimented, and evaluated. With the recognition that in order to verify the superiority of the semantic retrieval technology through test results of the CoWDC and efficiently integrate it into the e-Government, creation of a thesaurus, management of the operating system, expansion of the knowledge base and improvements in search service and accuracy at the national level were needed.

This study presents a multilingual integrated ontological approach that enables linking classification systems. thesauri. and terminology databases in science and technology for more effective indexing and information retrieval online. In this integrated system, we designed a thesaurus model with concept as a unit and designated essential data elements for a terminology database on the basis of ISO 12620 standard. The classification system for science and technology adopted in this study provides subject access channels from other existing classification systems through its mapping table. A prototype system was implemented with the field of nuclear energy as an application area.
