Building VR Learning Environment: An Ontology Based Approach

In this paper we describe an ontology based framework for describing VR objects and VR environment, reasoning and building of virtual learning environment scenario. A method is firstly proposed to semantically annotate according to the learning domain knowledge. Four kinds of semantic models are presented to describe the learning environment from different viewpoints.A simple semantic script language is suggested in order that we can describe a learning environment easily. The mapping method of the semantic modal and the VRML modal is advised. We also discuss the design and implementation technology based on our approach.
