The purpose of this paper is to design a model of integrated OPAC called as EconRef. This model not only provides users of libraries with systematic, rapid information service, but also supports librarians to do their tasks effectively. The designed model is constructed based on two operating systems such as REGIS system and The Book House and is developed by using KPWin++ is an expert system shell which combines hypertext and expert system functions. The designed system consists of six modules ; three reference expert systems for document sources, experts and statistical sources; OPAC ; external database ; user's guide. For the evaluation of the designed system, performance of EconRef system is compared with that of the naive and expert reference librarians. And also the features of the system are compared with those of REGIS systems. The tests comparing BconRef system searching with librarians searching have shown that EconRef system is at least as good as searching with expert librarians and much superior to searching with naive librarians.

본 연구에서 구축하고자 하는 통합OPAC은 특정 주제의 문헌정보원, 전문가정보원, 통계정보원을 제시해 주는 참고봉사 전문가 시스템, 온라인 열람목록(OPAC), 이용 안내, 외부데이타베이스의 검색 모듈이 결합된 시스템이다. 지식베이스는 문헌정보원 지식베이스, 전문가정보원 지식베이스, 통계정보원 지식베이스로 구성된다. 지시베이스의 추론방법은 전진추론(forword chining) 방식을 채택하였다. 시스템의 구현 환경은 먼저 하드웨어는 IBM 호완기종의 개인용 컴퓨터들(IBM386-DX33이상)을 사용하고 시스템 개발도구로는 전문가시스템과 하이퍼텍스트가 결합된 쉘(shell)인 KPWin++를 이용하였고 문헌정보원, 전문가정보원, 통계정보원에서의 키워드추출 등 정보처리 작업은 터보C를 사용하였다.
