A framework for ontology-driven multimedia analysis and composition

The task of resource retrieval and composition is particularly challenging in the case of multimedia resources. Usual approaches focus on the use of textual multimedia annotations to enable computer-based management of multimedia repositories. In this paper, we introduce two approaches which make use of a logical formalism called an ontology to improve on the state of the art in multimedia retrieval and composition. Through the use of ontologies, these approaches form apart of the emerging semantic Web, and offer important contributions to enabling multimedia-based semantic web applications.
