This study suggests the establishment and applications of the News core thesaurus for efficient indexing and searching of news information. News core thesaurus was constructed as macrothesauri which can cover all of news subjects and then has microthesauri like politics, economy, society, culture, etc. as its subsets. In this research, News core thesaurus embodied 2,012 descriptors and 74 non-descriptors by SKOS(Simple Knowledge Organization System). It suggests measures that treat only special subjects in detail in weekly newspaper or biweekly newspaper with little information and special subjects, which is not daily newspaper, and use each microthesauri by merging or integrating in huge news archives or portal sites.

Traditionally, the construction industry field is one of the typical fields using facet analysis method. Internationally the facet analysis method is applied to the classification scheme "Uniclass" or thesaurus "Construction Industry Thesaurus(CIT)". In the case of Korea, the facet analysis method is being used in classification scheme "Construction Industry Classification System" but it is difficult to find studies on facet analysis method in thesaurus or building case study. This study aims to establish facet types by introducing building of thesaurus for information retrieval in construction field using facet analysis method and to suggest building plan of thesaurus in construction field using facet analysis method. In this paper, We establish the 11 top facets(agent/patient, artifacts, abstract, material, parts/component, works, attribute, media, process, space, time) and the 13 subfacet as rudimental facets and suggest building plan according to thesaurus building procedure which is suggested by International Standard(ISO 25964-1). The result of this study is expected to apply to facet based thesaurus. And it is also expected to reuse in Taxonomy or Ontology etc. and to use in interoperability with the classification scheme of Construction filed.

이 논문은 공학적인 접근 방법에 기반한 단계적인 전문분야 시소러스 구축 방법을 제안한다. 시소러스 구축 과정은 용어 추출 단계, 용어 분류 단계, 계층 구조 구축 의 3단계로 구성되고, 모든 단계에서 자동 처리와 전문가 검증 작업을 거친다. 추출된 용어를 미리 정해진 분류 체계에 따라 분리한 후 여러 개의 작은 시소러스를 구축하고, 마지막으로 전체 시소러스로 결합한다. 이 방법은 1) 시소러스를 구축하는 복잡도가 줄어들고, 2) 클래스 단위의 작은 시소러스가 다른 전문분야 시소러스에 쉽게 재사용 될 수 있으며, 3) 각 클래스에 포함된 용어들의 분포를 쉽게 판단할 수 있는 장점이 있다. 제안한 방법을 이용하여 한국어 정보기술 분야 시소러스를 구축하였다. 시소러스 구축에 사용된 용어들은 정보기술 분야의 최근의 한국어 신문과 특허 문서에서 추출하였기 때문에 한국에서 만들어진 신조어를 포함한다. 구축된 시소러스는 81 개의 상위 레벨클래스와 1,000개 이상의 용어로 구성된다.

Collecting terms in thesaurus construction work is the most difficult. A dictionary is thesaurus can be used as an excellent term acquisition. Reflect faithfully the provisions of Korean literary "Standard Korean Dictionary" is a standard dictionary of the Korea. The "Standard Korean Dictionary" is simply the definition of entry, as well as a wide range of information about the term because it contains a systematic, it can be used to build a thesaurus. In this study, the "Standard Korean Dictionary" has the relevant information using a variety of terms, it is defined as the thesaurus term relationship. In addition, the separation of the term, equal relationships and hierarchical set of relationships, the use of qualifiers, North Korean issues, the issue presented in thesaurus construction, and suggest ways to solve the problem.

The thesaurus can control the headings in a classification scheme and can serve as an index of the classification scheme itself. In records management, the thesaurus controls functional terms and expands the access point of search to complement the functional classification scheme. In recent years, ISO 25964, the international standard for thesaurus construction, has been revised because of changes in the information environment and the development of thesaurus construction and utilization systems. Part 1 of ISO 15489, the international standard for overall records management, was also amended in 2016. In addition, the Integrated Public Sector Vocabulary (IPSV) in the UK, EuroVoc in Europe, and Functions of New Zealand (FONZ) in New Zealand have been effectively building and linking thesauri to reflect recent trends. In this study, we propose a thesaurus construction guideline for systematic record management in terms of related standards and cases, and suggest an improvement plan for the thesaurus construction guideline in Korea.

This study suggests the method of converting thesauri to SKOS step by step and it is formalized in three stages of the conversion process. The study develops output and guidelines for each stage. The converting stages are: (1) Collecting and analyzing thesauri for understanding about structure of terms and semantics of relation. (2) Defining the conversion method and creating ontology of the thesauri. (3) Examining the preservation of forms and various semantic relations between the thesauri and then creating SKOS ontology. This method can be applied to the thesauruses with complicated relations in concepts. In the future, it is needed to have an embodiment of conversion after making the algorithm of conversion by stage with the method suggested in this research.

In this paper, we proposed one of the methods for building thesaurus in Science & Technology domain and investigated its applicability as an inference service based on ontology. There exist as many building methods for thesaurus as its role and function, and actually many thesauri capable of ensuring the accuracy and efficiency in information search are being built by many experts. After examining the previous studies related to the principles of building thesaurus and relevant concept "facet", we focused on its characteristics and applied it to building thesaurus. The facet is classified into 2 categories, conceptual facet and relational facet. The latter contains 3 subcategories: category relational facet, attribute relational facet and thematic relational facet. The thesaurus for Science & Technology domain using facets can be applied as a web-based inference service. As a result, the three types of inference service, COP(Communities of Practice), Researcher Tracing and Research Map are provided by means of ontology, and can be applied for the Query Expansion.

시소러스 의미망, 온톨로지 등과 같은 지식베이스는 자연언어처리와 관련된 여러 분야에서 중요한 언어자원의 역할을 담당하고 있다. 하지만 정보검색, 기계번역과 같은 특정 분야마다 다르게 구축되어 이러한 지식베이스는 실질적인 한국어 처리에는 크게 효과를 보지 못하고 있는 실정이다. 본 논문은 한국어를 대상으로 한 시소러스, 의미망의 등의 구축 방법론적 문제를 지적하고 말뭉치를 중심으로 한 텍스트 언어처리에 필요한 의미망의 구축 방법과 포괄적인 활용방안을 모색한다. 의미망 구축의 기반이 되는 지식은 각종 사전(dictionary)를 이용했으며, 구축하고 있는 의미망의 활용 가능성을 평가하기 위하여 ETRI의 의미기반 정보검색과 언어처리의 큰 문제 중 하나인 단어 중의성 해소(WSD)에서 어떻게 활용되는지를 살핀다. 그리하여 언어자인의 처리 방안 중의 하나인 의미망을 구축함으로써 언어를 효과적으로 처리하기 위한 기본적이면서 중요한 어휘 데이터베이스 마련과 동시에 언어자원 구축의 한 방향을 제시하고자 한다.

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.
