엘리먼트 기반 XML 문서검색의 성능에 관한 실험적 연구 = An Experimental Study on the Performance of Element-based XML Document Retrieval

다국어 초록 (Multilingual Abstract)

This experimental study suggests an element-based XML document retrieval method that reveals highly relevant elements. The models investigated here for comparison are divergence and smoothing method, and hierarchical language model. In conclusion, the hierarchical language model proved to be most effective in element-based XML document retrieval with regard to the improved exhaustivity and harmed specificity.

국문 초록 (Abstract)

이 연구에서는 가장 적합한 엘리먼트 기반 XML 문서검색 기법을 제시하기 위해 언어모델 검색 접근법으로 다이버전스 기법, 보정 기법 그리고 계층적 언어모델의 검색성능을 평가하는 실험을 수행하였다. 실험 결과, 가장 효율적인 검색 접근법으로 문서의 구조정보를 적용한 계층적 언어모델 검색을 제안하였다. 특히, 계층적 언어모델은 실제 검색에서 중요성을 가지는 검색순위 상위에서 뛰어난 성능을 보였다.
