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.

In the current information environment, metadata interoperability has become the predominant way of organizing and managing resources. However, current approaches to metadata interoperability focus on the superficial mapping between labels of metadata elements without considering semantics of each element. This research applied facet analysis to address these difficulties in achieving metadata interoperability. By categorizing metadata elements according to these semantic and functional similarities, this research identified different types of facets: basic, conceptual, and relational. Through these different facets, a faceted framework was constructed to mediate semantic, syntactical, and structural differences across heterogeneous metadata standards.

UNESCO clearly has a good user interface compared to other sites. However, it does not have a structure in which user-centric knowledge curating is employed by users. As such, the knowledge structure should be expressed differently in advance for users to enjoy such benefits. At present, almost all current information systems are lacking with semantic and contextual information. Moreover, these systems are deemed insufficient of interlinking various kinds of thoughts in our minds. Thus, it is necessary to model in advance what users are likely to think and provide an interface that they can easily utilize based on that modeling. Furthermore, there is a need for a new structural theory based on semantic technology that can make that possible. Therefore, in this proposal, theoretical and practical insights were presented for user interface implementation to which relational facet navigation based on the structural theory is applied. Moreover, this proposal intends to suggest a "thinking expansion platform" that allows users' ideation of different concepts, including those unfamiliar to them.

본 논문에서는 시소러스 상에서 개념간 세분화를 위한 의미적 기준인 개념 패싯 (Conceptual Facet)과 관계 패싯 (Relational Facet) 그룹을 사용하는데, 패싯이란 공통의 특성을 갖는 개념들을 함께 그룹화하고 용어간 관계를 구조화하기 위한 장치이다. 개념 패싯은 용어가 갖는 대표적인 의미속성, 범주를 의미하며, 용어 각각을 구별되는 의미장 (Semantic Field)에 분류하도록 한다. 관계 패싯은 상$\cdot$하위 개념 간 의미 관계를 표현한 메타 개념이다. 본 시소러스는 여러 전문가들의 다양한 관점을 반영하도록 설계되었다. 관점이란 주관적이며, 임의적이어서 개별 개념에 내재된 자질 또는 속성과는 구별되는 독립적 속성이다. 개념 패싯, 관계 패싯의 도입은 계층 관계, 동등 관계, 범주 관계 등과 더불어 용어 간 관계를 보다 구체적으로 명시함으로써 최종 사용자에게 검색의 효율성과 정확성을 제공할 수 있다.

This paper is to describe how to refer to software objects and reuse them through the web browser so that ail the members of the software development team can collaborate with each other on the development procedure, In addition, we describe how to convert the $ ^*$,mdl design information generated from the UML editor into their corresponding XML data, which is arranged to be saved in the relational database system. Furthermore, we provide a facet retrieval system based on which makes use of a object-oriented thesaurus, which supports an integrated environment through which all the project team members can share a lot of source codes and execution files as weil as object files produced from the web-based collaborative development environment. Finally, we have designed and implemented a web version management system that facilitates software developers to manage in their web-based search for the relationship of design informations.
