The Organization and Application of Multimedia information Based on Ontology

In order to use the multimedia sources efficiently, finding the semantic content behind the resources and analyzing them, a framework to uniformly describe multimedia resources is used in this paper by using the theory of ontology. Based on fifteen elementary metadata of Dublin Core Metadata Element Set, the notion of the Basic Metadata and Expand Metadata are defined to realize the unify description and separate expression. In this way, the current metadata format from most multimedia resource can be satisfied, and also the self-definition and expansion can be made according to the different applications. This framework has been satisfactorily used in real media resource management System for multimedia content organization, query and exchange.
