Abstract: Currently, information visualization is facing a bottleneck a model is needed to integrate the scene graphics content and the semantic information of specific areas effectively so that the users can effectively interpret, personalize the visualized information. Based on the X3D standard and Ontology, the Web ontology Language named OWL was usedto descript the X3D standard and then a X3D standard ontology and a mapping ontology used to implement the mapping of classes and attributes between the X3D standard ontology and the other specific domain ontology were built to enrich the semantics of virtual scene. Based on the X3D standard ontology and the mapping ontology, a semantic virtual environment ontology visualization model was designed to provide a method for the visualization of specific ontology. The feasibility of this model was proved by the experimental results.

Key words: X3D, Semantic virtual environment, Ontology, OWL, Ontology mapping
