시멘틱 웹 서비스의 최종적인 목표는 네트웍으로 연결된 프로그램들과 장치들이 사람의 명령 없이 긴밀하게 상호작용 하는 것이다. 시멘틱 웹은 정보의 의미를 알 수 있는 프레임워크를 연구하였는데, 이는 인공지능을 기반으로 하는 RDF. RDFS, DAML+OIL, OWL등의 언어를 기반으로 하여 연구되었다 시멘틱 웹 커뮤니티에서는 웹의 정보 뿐 아니라 서비스에도 정확한 의미를 부여하기 위해서 DAML+OIL 온톨로지 기반의 새로운 기술인 DAML-S 온톨로지 기술을 제안하였다. DAML-S는 Service. Service Profile. Service Model. Service Grounding의 4개의 상위 온톨로지로 구성되는데, 특히 Service Profile, Service Model 온톨로지와 인스턴스를 이용하여 사용자의 요구에 적합한 서비스 검색과 Composition01 가능하다. 사용자의 요구가 atomic 서비스가 아닌 여러 atomic 서비스들을 함께 이용해야 하는 경우에는 시멘틱 웹 서비스 검색 시스템 외에 추가적인 웹 서비스 Composer가 필요하게 된다. 본 논문에서는 사용자의 요구로부터 필요한 웹 서비스 chain을 구성함에 있어서 사람이 개입하지 않는 STRIPS 타입의 자동 웹 서비스 Composer를 제안한다.
