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.

Although ISO 25964-2 was introduced in 2013, existing research about it that can be used for analysis and basis for its application is scarce. This study analyzed the interoperability of vocabularies emphasized in ISO 25964-2. First, this study examined the mapping types of the concept sharing method. In addition, based on the mapping types, this study sought for and examined the interoperability method between a thesaurus and ontology. Lastly, this study has suggested a thesaurus and ontology interoperability model and designed and constructed an ontology model for administrative department names in Korea to verify the possible of the model.

This is an overview of the TEST which effects on the development of thesaurus. Such term relations, display methods, classification schemes for the conventions of the thesaurus development are explained. This conventions of the TEST also effected on the ANSI guideline as well as UNESCO guideline for the thesaurus development. This explains on the development of microthesaurus through its application of TEST.

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.

Despite a long tradition and rich discussion of thesaurus construction, more research is needed to make standards for thesaurus construction applicable to practice. Recently, in order to reflect changing information technology environment, and provide consistency of terms and abbreviations of standards, ISO committee has been planning to publish ISO 25964. Therefore, the study introduces ISO 25964, reveals main focal points of ISO 25964, and finally discusses suggestions to improve ISO 25964. The study employs qualitative content analysis of ISO 25964, ISO 2788: 1986, and ANSI/NISO Z39.19 - 2005.

In this paper we propose a formal data model of an object-based thesaurus system supporting multi-dimensional facets. According to facets reflecting on respective user perspectives, it supports systematic construction, browsing, navigating and referencing of thesauri. Unlike other faceted thesaurus systems, it systematically manages its complexity by appropriately ing sophisticated conceptual structure through visualized browsing and navigation as well as construction. The browsing and navigation is performed by dynamically generating multi-dimensional virtual thesaurus hierarchies called "faceted thesaurus hierarchies." The hierarchies are automatically constructed by combining facets, each representing a dimension of view. Such automatic construction may make it possible the flexible extension of thesauri for they can be easily upgraded by pure insertion or deletion of facets. With a well defined set of self-referential queries, the thesauri can also be effectively referenced from multiple view points since they are structured by appropriately interpreting the semantics of instances based on facets. In this paper, we first formalize the underlying model and then implement its prototype to demonstrate its feasibility.

백과사전 데이타베이스의 효과적인 검색을 위한 색인시스템을 설계하였다. 여기에서는 항목에 대한 각종 속성정보와 본문정보를 모두 포함한 색인표제어파일을 작성하고, 각 항목에 대한 참조항목을 별도로 두지 않고 시소러스파일의 BT, NT, RT, UF를 사용하여 그 항목과 연관된 항목을 참조하도록 한다. 시소러스파일은 각 색인표제어에 부여한 주제분류기호(DDC, 또는 KDC)의 계층구조를 이용하여 자동생성한 후 색인자의 수작업을 거쳐 작성된다. 이 색인시스템을 통해 백과사전에 포함되어 있는 모든 정보를 이용한 다양한 접근이 가능하며 시소러스를 사용하여 관련항목을 브라우징을 할 수 있어 포괄적인 검색이 가능하다.

시소러스를 구축하기 위해서는 해당분야의 심도깊은 이해와 지식이 필요하다. 특히, 디스크립터의 선정과 디스크립터의 관계설정은 시소러스 개발자의 주관적인 판단에 따라 이루어지게 된다. 그러나 디스크립터의 선정은 자동색인분야의 연구로서 어느 정도 객관화가 가능하지만, 디스크립터개념간의 관계설정은 개발자의 주관에 전적으로 의존하게 된다. 본 논문은 자연어처리방법과 문헌내 용어출현빈도를 근거로 기계를 이용한 디스크립터간의 관계 설정방안을 제시하고 그 가능성을 조사하였다.

The aim of this article is to study the new searching tool for era of multimedia. Thesaurus is a useful tool but is constituted with noun phrase including the adjective for retrieving the human Sensibility. Therefore, I experimentally construct the Sensibility thesaurus using the color scale which contains the Sensibility meanings. Terms are 261, Relation standards are distance and ratio of reiteration between the terms. I would use an exclusive program of the thesaurus construction for Sensibility adjective.

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.
