Abstract

XML documents format on the Web provides a mechanism to impose their content and logical structure information. Therefore, an XML processor provides access to their content and structure. The purpose of this study is to investigate the usefulness of structural hints in the leaf node language model-based XML document retrieval. In order to this purpose, this experiment tested the performances of the leaf node language model-based XML retrieval system to compare the queries for a topic containing only content-only constraints and both content constrains and structure constraints. A newly designed and implemented leaf node language model-based XML retrieval system was used. And we participated in the ad-hoc track of INEX 2005 and conducted an experiment using a large-scale XML test collection provided by INEX 2005.

XML웹 문서 포맷은 문헌 내에 내용과 의미있는 논리적인 구조 정보를 포함할 수 있어, 검색에서 문서의 내용뿐만 아니라 구조로 접근하는 것을 제공한다. 그래서 본 연구의 목적은XML검색에 있어 내용 검색에 추가적인 요소로 사용된 구조적인 제한이 얼마나 유용한지를 실험하기 위해 내용만으로 검색한 결과와 내용과 구조적인 제한을 가지고 검색한 결과간의 성능을 비교하였다. 이 실험은 자체 개발된 단말노드 언어모델기반의 XML 검색시스템을 사용하였고 INEX 2005의 ad-hoc track에 참여하여 모든 실험방법과 INEX 2005의 실험 문헌 집단을 사용하였다.
