Research on knowledge communication of dynamic virtual communities based on ontology

The wide-range applications on Web promote the renaissance of the semantic Web and knowledge is one of the valid approaches that realize the semantic Web. Knowledge communication is a common key issue. This paper studies the related research topics firstly, gives a coarse definition of the knowledge communication connotation and puts forward its characteristics. At the same time, recurring to the idea of the virtual community of the grid and the ontology technology, we establish a kind of knowledge communication structure consisting of dynamic virtual communities based on ontology. In order to improve routing quality, a high-level directory table classified by domain and community and a multi-dimensions knowledge directory table are based on ontology. In addition, task-metaknowledge-base, task-case-base, rule base, ontology knowledge base are designed based on ontology and routing service agents are created who can accomplish discovery, mediating and locating service resources in this paper. All of these constitute the decentralized controlling knowledge routing system. At last some expectation about the knowledge communication is proposed.
