| Content Summary | In this paper, we describe a framework that we have developed for the support of ontology-based semantic indexing and retrieval of audiovisual content following the MPEG-7 and TV-Anytime standard specifications for metadata descriptions. Our work aims to provide a methodology to enhance the retrieval effectiveness of audiovisual content, while maintaining compatibility with the international multimedia standards. In our framework, domain-specific ontologies guide the definition of both the application-specific metadata and the instance-description metadata that describe the contents of audiovisual programs and/or their segments. The ontologies are also used in order to provide compatible descriptions in both audiovisual content standards (MPEG-7 and TV-Anytime) for the same content. This approach allows indexing compatibility and interoperability of TV-Anytime and digital library applications. We describe the design and implementation of a system supporting this framework. The components of the system include a segmentation tool for segmenting audiovisual information, which also provides ontology-based semantic indexing capabilities, and an appropriate API for semantic query support. An application testbed for the domain of soccer games has been developed on top of this system. An ontology for soccer games has been defined and used for indexing and retrieval of soccer games that have been stored in the system database. The methodology we developed opens up a wide opportunity for the creation of MPEG-7 and TV-Anytime services offering structured domain-specific ontologies that can be integrated to these standards for enhancing audiovisual content retrieval performance. | en |
