Abstract

This study aims lo enhance the perfor~nance 01 concept-based information retr~eval through the use of the lraditional thesaurus which, clearly delmes relalions among terms. To achwe lhls, thc study purports to construcl relation-value-based, relalion-bad, and inlegated kumwledge bases tluough the use ol ihc lhcsau~ub. To cornpale and a~alyze retrieval perlor~nance among knowledge bases, two methods weue al~plied. Sequential bnb algorithm is ap~lied to the I-clation-ualue-based and intzgralcd knowledge base while heuristic bnb algorithm is applied to the relal~on-based knowlcdgc base.

본 연구에서는 인간 전문가에 의해 용어간의 관계가 명확하게 정의된 전통적인 시소러스를 활용함으로써 기념개반 정보검색의 성능을 향상시키고자 하였다. 이를 위해 시소러스를 활용하여 관계값기반, 관계기반, 그리고 통합형 지식베이스를 구축하였다. 관계값기반 지식베이스와 통합형 지식베이스에는 순차적 bnb 알고리즘을 적용하고 관계기반 지식베이스에는 경험적 bnb 알고리즘을 적용하여 지식베이스간 검색성능을 비교분석하였다.
