Application of Ontology to Question-Answer Knowledge Management System

Knowledge Management (KM) has become an important success factor for enterprises and organizations. The knowledge is organized as "Subject-Action-Object" form in this paper. And the five procedures of KM: knowledge creation, knowledge extraction, knowledge classification, knowledge retrieval and knowledge sharing and reuse are discussed in this paper. The user query will be expanded based on Ontology during the process of knowledge retrieval and more semantic related results will be gotten. The knowledge can be efficiently searched and thus reusable by the proposed method.
