The paper analyses graph oriented method for ontology transformation into conceptual data model. A number of methods were proposed to develop conceptual data models, but only few deals with knowledge reuse. In this paper we present an approach for knowledge represented by ontology automatic transformation into conceptual data model. The graph transformation language is presented and adapted for...

Ontology formal model and ontology checking recently are still under hot discussion. In this paper, an ontology concept model is constructed using Description Logics.
