An extension of MPEG Query Format to support Knowledge-Based Multimedia Information Retrieval based on KQML

The MPEG Query Format (MPQF) which MPEG Group is developing is to standardize query interface for XML-based multimedia retrieval systems. MPQF provides query types for Information Retrieval and Data Retrieval over XML Database in the current draft. As more and more multimedia metadata modeled with semantic ontology like RDFS and OWL are stored in the Knowledge Base, there is a requirement for querying multimedia information over Knowledge-Based system. In this paper we propose the necessary extension (QueryByKQML type) which will allow MPQF to support Knowledge-Based Multimedia Information Retrieval based on Knowledge Query and Manipulation Language (KQML).
