Abstract: Aiming at making up the lack of present ontology representation methods in describing virtual enterprise model, a graphic ontology representation schema, called Ontology Structure Graph (OSG), which adapted to describe virtual enterprise model was put forward. Based on the analysis of virtual enterprise model and its characteristics, semantic relationship and constraint rules of OSG were defined formally. An OSG instance of partial virtual enterprise model was given to illustrate in detail how to create an OSG. Furthermore, an ontology description language for virtual enterprise model which was expanded from eXtensible Markup Language(XML) was proposed. Its basic elements and document structure were illustrated, and its associations and constraints were described in particular. Finally, the feasibility and advantages of ontology representation method were analyzed through comparing to other ontology representation methods.
