TY - JOUR U1 - Teil eines Periodikums A1 - Arndt, Richard A1 - Staab, Steffen A1 - Troncy, Raphael A1 - Hardman, Lynda T1 - Adding formal semantics to MPEG-7 BT - designing a well-founded multimedia ontology for the Web N2 - Semantic descriptions of non-textual media available on the web can be used to facilitate retrieval and presentation of media assets and documents containing them. While technologies for multimedia semantic descriptions already exist, there is as yet no formal description of a high quality multimedia ontology that is compatible with existing (semantic) web technologies. We explain the complexity of the problem using an annotation scenario. We then derive a number of requirements for specifying a formal multimedia ontology, including: compatibility with MPEG-7, embedding in foundational ontologies, and modularisation including separation of document structure from domain knowledge. We then present the developed ontology and discuss it with respect to our requirements.
