Abstract

This paper reviews various industry efforts to formalize the semantics of multimedia metadata and develop tools for the automatic extraction of semantic metadata from media assets. These efforts are particularly relevant to today's media industry because of the commonly recognized importance of semantic metadata in effectively supporting various media-related activities (e.g. multimedia data management, intelligent search and retrieval, Web access, personalization, etc.), and because of the high cost usually associated with the manual creation of such metadata This paper aims to provide a taste of some major research trends in this area, and to illustrate these trends via concrete examples of relevant projects. The focus is on MPEG-7 and Semantic Web technologies, for reasons described in the Introduction. This paper is not intended to be a comprehensive survey of academic and industrial efforts currently addressing the subject of multimedia semantics, which are too numerous and varied in scope to be discussed in a single paper. After a brief presentation of the semantic description features of MPEG-7, the paper discusses current work intended to leverage Semantic Web technologies to address multimedia semantics. Work to translate MPEG-7 semantic constructs into machine-processable ontologies and work attempting to automatically populate MPEG-7-based semantic annotations of multimedia content are discussed.
