Abstract

To evaluate the retrieval effectiveness of the B03lean Request Conversion Mod4 the Relevance Weighted Boolean Model, and the P-NORM Model, the present study has been done with expenmental tests. It is proven that the Relevance Weighted Bdean Model is more effective in precision and the document output ranks than the other ones. The expenmental results indmte a promisii application of relevance mformation and weigh- schemes.

본 연구에서는 검색실험을 통하여 질문 변환에 의한 불 논리 검색, 적합성 가중치 검색, P-NORM 검색에 대해 평가하였다. 적합성 가중치 검색은 질문 변환에 의한 불 논리 검색 및 P-NORM 검색보다 정확률과 검색순위에 있어 효과적이었다. 정보 탐색과정에서 적합성 정보의 이용수준과 용어에 대한 가중치방법은 검색성능에 영향을 주는 것으로 밝혀졌다.
