Using Ontology Repository to Support Data Mining

Ontology plays the central role in the information system. A novel framework for data mining process is proposed, using ontology repository to integrate domain knowledge. Ontobase ontology repository is an implementation of our design to allow users and agents to retrieve ontologies and metadata through open Web standards and ontology service. Key features of the system include the use of XML metadata interchange to represent and import ontologies and metadata, the support for smooth transformation and transparent integration using ontology mapping and the use of ontology services to share and reuse domain knowledge in a generic way. Some examples show that Ontobase is useful in supporting data mining process
