Abstract

XML is increasingly important in data exchange and information management. A large amount of efforts have been spent in developing efficient techniques for accessing, querying, and storing XML documents. In this paper, we propose a new method to cluster XML documents efficiently. A new prepresentative path called a virtul path which can represent both the structure and the contents of a XML document is proposed for the feature of a XML document. A method to apply the well known hierarchical clustering techniques to the representative paths to cluster XML documents is also proposed. The experiment shows that the true clusters are formed in a compact shape when a virtual path is used for the feature of a XML document.

XML은 데이터 교환과 정보 관리에 점차 중요해지고 있다. 근래에 XML 문서들에 대한 접근, 질의, 저장을 위한 효율적인 기법들을 개발하기 위해 많은 노력들이 이루어지고 있다. 이 논문에서 우리는 XML 문서들을 효율적으로 군집화하는 새로운 방법을 제안한다. XML 문서의 특징을 위해 XML 문서의 구조와 내용을 대표할 수 있는 새로운 대표 경로, 즉 가상 경로가 제안된다. XML 문서들을 군집화하기 위해 잘 알려진 계층 군집화 기법들을 대표 경로들에 적용하기 위한 방법도 제안된다. 실험을 통해 XML 문서의 특징으로 가상 경로를 사용했을 때 실제적인 군집들이 촘촘한 형상으로 잘 형성됨을 알 수 있다.
