적합성피이드백을 이용한 전문검색시스템의 검색효율성 증진을 위한 연구

  • Published : 1993.12.01

Abstract

The primary purpose of the study is to improve the low preclslon often found In full-text retrleval systems. In order to enhance the low precision of full-text retrleval wh~le retaining ~ t s hgh recall, relevance feedback mechanisms based on probabilistic retrieval models (binary independence and two-Polsson Independence models) were employed. Thls paper investigates the effect of relevance feedback on the performance of full-text retrieval systems.

본 연구의 주목적은 전문검색시스템의 문제점인 낮은 정확율을 향상시키는 검색기법을 제시하는 것이다. 높은 재현율을 유지하면서 정확율을 증진시키기 위하여 확률검색모형 (이진독립형과 투포이슨독립모형)에 기초를 둔 적합성피이드백을 이용하였고, 이것이 전문검색시스템의 검색효율성에 미치는 영향을 조사하였다.
