Towards bridging the semantic gap in multimedia annotation and retrieval (original) (raw)

We present a systematic approach to the design of multimedia ontologies based on the MPEG-7 standard and domain-specific vocabularies. The limitations of MPEG-7 in describing the semantics of highly structured domains like sports or medicine has led to an upsurge of interest in adopting an integrated approach to the design of ontologies. We follow suit and use MPEG-7 to model structural and low-level aspects of multimedia documents. The high-level semantics are modeled using a domain-specific ontology designed for soccer games. The integration of these ontologies is achieved by providing appropriate links to the individual ontologies. As a proof-of-concept, we describe a video annotation tool implemented as a plugin for the widely used Protégé ontology editor. The advantage of our methodologies lies in the fact that we use semantic web compliant languages and tools that results in alleviating the interoperability issues currently plaguing the multimedia and the semantic web communities.
