Abstract

Need for machine-understandable web (Semantic web) is increasing in order for users to exactly understand Web information resources and currently there are two main approaches to solve the problem. One is the Topic map developed by the ISO/IEC JTC 1 and the other is the RDF (Resource Description Framework), one of W3C standards. Semantic web supports all of the metadata of the Web information resources, thus the necessity of interoperability between the Topic map and the RDF is required. To address this issue, several conversion methods have been proposed. However, these methods have some problems such as loss of meanings, complicated structure, unnecessary nodes, etc. In this paper, a new method is proposed to resolve some parts of those problems. The method proposed is called NOWL (NO structural Warp and semantics Loss). NOWL method gives several contributions such as maintenance of the original a Topic map instance structure and elimination of the unnecessary nodes compared with the previous researches.

웹의 급속한 발전과 함께 웹 정보 자원을 보다 정확하게 이해할 수 있는 시멘틱 웹에 대한 필요성이 증가하고 있다. 현재 이와 관련된 두 가지 표준이 존재하는데 하나는 ISO/IEC JTC 1 표준인 토픽맵(Topic map)이고, 다른 하나는 W3C 표준인 RDF(Resource description framework)이다. 그러나 시멘틱 웹은 토픽맵을 적용한 정보자원과 RDF를 적용한 정보자원을 모두 인식할 수 있어야 하므로 토픽맵과 RDF간의 상호운용성이 요구된다. 이를 위해 토픽맵과 RDF간에 상호운용성 문제를 해결하기 위한 여러 변환 방법들이 제안되어 왔다. 그러나 기존의 방법들은 의미의 손실, 복잡한 구조, 불필요한 노드의 추가 등과 같은 문제점을 지니고 있었다. 이 논문에서는 이러한 문제를 해결하기 위한 새로운 방법인 NOWL (NO structural Warp and semantics Loss)을 제안한다. 제안한 방법은 기존 방법에 비해 토픽맵 본래의 의미 구조를 유지하고 불필요한 노드의 생성을 제거하는 등 여러 가지 장점을 지닌다.
