Abstract

An ontology as the core element of Semantic Web is a formal specification of a conceptualization of shared domain knowledge. The use of well-defined ontologies can increase the quality of interoperable information systems in the area of Semantic Web. However, in practice, it is not easy to develop high-quality ontologies which have no errors. Therefore, with methodologies for ontology design, various methods or tools for ontology analysis supporting for error-detection might be very helpful for ontology developers. In this paper, we propose a novel approach for analyzing the core constructs of ontology based on the Formal Concept Analysis and develop a tool that supports error-checking ontologies. Our approach can serve not only as a guidance to modify the existing ontologies, but also as a valuable tool in developing high-quality ontologies.

온톨로지는 시멘틱 웹의 핵심요소로서, 도메인의 공유지식을 개념화하여 정형적으로 표현한 것이다. 잘 정의된 온톨로지를 사용함으로써 상호운용성을 기반으로 하는 시멘틱 웹 분야의 정보시스템 품질을 향상시킬 수 있다. 그러나, 실제로는 오류를 포함하지 않는 고품질의 온톨로지를 개발하는 것은 수월하지 않다. 따라서, 온톨로지 설계기법과 더불어서, 온톨로지에 내재된 에러를 검출하는 기능을 지원하는 다양한 분석도구/기법들은 온톨로지 개발자들에게 많은 도움이 될 수 있다. 본 논문에서는, 형식개념분석기법을 기반으로 온톨로지의 핵심요소들을 분석하는 기법을 제안하고, 온톨로지에 내재되어 있는 오류를 검출하기 위한 지원도구를 개발하였다. 본 연구결과는, 기존의 온톨로지를 수정보완할 경우의 지침으로서 뿐만아니라, 고품질의 온톨로지를 개발할 수 있는 유용한 도구로서 이용될 수 있다.
