In order to provide high quality of network information service for enterprise, the integration system of network information resources is designed based on multi-agent collaboration. The system may be logically divided into three function modules: User Module, Processing Module and Search Module. This paper presents the essential function of each constituent part, collection workflow, evaluation workflow, Web information retrieval workflow, and image information retrieval workflow of network information resources. The key technologies are also discussed in detail, including User Interest Model matching algorithm for user personalized service, and content based image retrieval algorithm. The system is provided with intelligence, flexibility, and robustness.
