인터넷이 급속히 발전하고 확산되면서 정보를 효율적으로 활용하고 유통시키기 위한 연구가 활발히 진행되고 있다. OAI(Open Archives Initiative)에서는 대용량 정보를 메타데이터를 이용하여 공유하고 검색할 수 있는 프로토콜 및 임프라에 대한 연구와 표준화를 추진하고 있다. 또한 EMAF(An Extensible Multi-Agent Framework)에서는 멀티에이전트를 이용한 정보 유통 및 활용한 대한 연구가 진행중이다. 이에, 본 논문에서는 메타데이타과 XML, 멀티에이전트를 이용한 분산검색 시스템을 설계하고 구현하였다. 본 시스템은 조정에이전트와 응용에이전트로 구성되고 에이전트간 통신에는 XML과 OAI의 메타데이타 하비스팅 프로토콜을 응용하였다. 메타데이터에 대한 검색을 수행하여 검색 성능을 높일 수 있었으며 또한 사용자가 입력한 문장 단위의 질의를 처리할 수 있는 기능과 관련어를 추출할 수 있는 기능도 제공한다.
