Dynamic semantic consistency checking of multiple collaborative ontologies in knowledge management system

An ontology-based knowledge management system uses an ontology to represent explicit specification of a special domain and to serve as a backbone for providing and searching for knowledge sources. But, dynamically changing domain environment implies changes in the conceptualization of the domain that are reflected on the underlying domain ontologies. Consequently, these changes have effects on the consistency and validity of the domain ontologies of the KM system. In this paper we present an approach for dynamic semantic consistency checking of multiple collaborative ontologies in KM system in the case of changes in the domain ontology. This approach is based on our research in the ontology reasoning.
