Ontology-based Web Knowledge Management 3C3.8

The knowledge management is becoming more and more important in organizations, either over the intranet or Internet. In this paper we present an ontology-based web knowledge management (KM) framework based on web ontology language DAML+OIL. This framework supports content-oriented rather than traditionally document-oriented approach to knowledge management. Three fundamental building blocks, i.e., annotations based on ontologies, knowledge-bases based on assertions in ontologies and web resources crawling, and rule-based reasoninghference system for semantic knowledge manipulation. Our approach to knowledge management is the result of our semantic web research efforts. We adopt the web-standard based tools in our development of knowledge management. We believe that this approach of annotation-crawlinginference (A-C-I) to knowledge management is flexible and effective in supporting knowledge sharing on the web. An ongoing prototype is briefly described.
