- W2080579985 abstract "발달된 인터넷 환경과 데이터 교환 표준 언어로서 확정되고 있는 XML을 기반으로 하여 대량의 웹 문서들이 생산되면서 정보 추출의 대상은 자연스럽게 웹 문서로 이동하게 되었다. 이에 따라 급속히 증가하고 있는 XML 문서에 대한 구조, 통합 및 검색을 위한 연구들이 있다. 이 논문에서는 XML 문서들에 대한 질의 처리, 검색 등을 효율적으로 처리하기 위한 기반으로써 빈발구조 중심의 XML 문서를 클러스터링 하는 방법을 제안한다. 첫째 XML 문서를 트리 구조로 표현하여 분리하고 분리된 구조들을 대상으로 빈발하게 발생하는 구조들을 추출한다. 둘째 각 XML 문서에서 추출된 빈발 구조들을 트랜잭션의 항목으로 취급하여 클러스터링을 수행한다. 클러스터링을 수행할 때 각 클러스터의 생성 및 생성된 전체 클러스터의 응집도를 함께 고려하는 주요항목 가중치를 이용한다. 셋째 기존연구와의 비교 실험을 통해 제안하는 방법의 우수성을 증명한다. As the web document of XML, an exchange language of data in the advanced Internet, is increasing, a target of information retrieval becomes the web documents. Therefore, there we researches on structure, integration and retrieval of XML documents. This paper proposes a clustering method of XML documents based on frequent structures, as a basic research to efficiently process query and retrieval. To do so, first, trees representing XML documents are decomposed and we extract frequent structures from them. Second, we perform clustering considering the weight of large items to adjust cluster creation and cluster cohesion, considering frequent structures as items of transactions. Third, we show the excellence of our method through some experiments which compare which the previous methods." @default.
