Abstract

This paper introduces a virtual hierarchical semantic framework for multimedia information grid according to the semantic relativity between multimedia information resources(MIRs) in semantic web. This framework includes the MIR semantic description model and organization model. On the basis of this framework, we propose the Virtual Semantic Resource Routing (VSRR) algorithm to improve the efficiency of searching MIR and provide the highly precise MIR locating. In this algorithm, we search MIR in multimedia information grid by routing among virtual semantic resource sub-grid according to the semantic relativity of the MIR. Finally, this paper analyzes the performance of VSRR algorithm.
