(Korean Abstract)
XML 문서가 가지고 있는 태그의 자유로운 정의와 내포된 구조 정보는 정보 검색 및 문서 관리 분야에 많은 이점을 제공할 수 있다. 본 논문은 XML 요소(element)의 의미와 구조 정보를 반영한 문서간의 유사성을 검사할 수 있는 XML 문서 분석 기법을 제시하고자 한다. 도출된 문서간 유사성은 많은 정보 검색 및 마이닝 등의 기초 자료로 사용될 수 있다. 먼저 XML 요소를 시소러스를 이용하여 유사어와 합성어로 구성된 확장-요소 벡터로 확장하고 유사 행렬을 구축하여 요소간 유사성을 판별한다. 또한 오토마타(NFA(Nondeterministic Finite Automata)와 DFA(Deterministic Finite Automata)(를 이용하여 XML 문서의 내포된 구조를 발견하고 최소화 한다. 요소간의 유사 행렬과 최소화된 XML 구조를 이용하여 구조간의 유사성을 판별한다. 본 논문의 XML의 의미를 반영한 유사성 분석 기법은 온라인 서점의 실제 문서의 카테고리를 인식하는 데 있어 100% 정확도를 보였다.

(English Abstract)
XML allows users to define elements using arbitrary words and organize them in a nested structure. These features of XML offer both challenges and opportunities in information retrieval and document management. In this paper, we propose a new methodology for computing similarity considering XML semantics - meanings of the elements and nested structures of XML documents. We generate extended-element vectors, using thesaurus, to normalize synonyms, compound words, and abbreviations and build similarity matrix using them. And then we compute similarity between XML elements. We also discover and minimize XML structure using automata(NFA(Nondeterministic Finite Automata) and DFA(Deterministic Finite automata). We compute similarity between XML structures using similarity matrix between elements and minimized XML structures. Our methodology considering XML semantics shows 100% accuracy in identifying the category of real documents from on-line bookstore.
