The Research And Design Of Ontology-Based Knowledge Discovery System

The knowledge management has already been a key method to enhance the competition of enterprise. Because the existing knowledge management system lack effective and efficient means for acquiring knowledge, we can only maintain system closely and use knowledge statically.According to this, we proposed an Ontology-Based Knowledge Discovery System Framework. It mainly focuses on the following issue:1, This article specifies an united knowledge model and a united specification storing knowledge which is the foundation used to construct knowledge discovery system. 2, This article also analyze Ontology evolution procedure more deeply, in which the Ontology is formalized by the OWL language.3, In order to enhance the means of knowledge management system which used to acquire knowledge, we implement a opened knowledge-acquiring tool. It can help knowledge-worker add a new knowledge to knowledgebase or update the knowledge in knowledgebase. This measure insures that the knowledge in knowledgebase is up-to-date and useful.
