Description
Ontology has recently received considerable attention in the knowledge management community. This article discusses the needs of ontology development for data mining. Based on a domain analysis of knowledge representations in data mining, it proposes a generic structure of ontologies for data mining. Furthermore, this article specifies the unique ontology resources of the subdomain of innovative data mining with incomplete data. A project on an ontology-based data mining system for discovering knowledge from incomplete data demonstrates the effectiveness of ontology in knowledge management.
