Semantic Annotation and Retrieval using Multimedia Ontologies

Today’s major problem in consumption of multimedia content from the Web is the extremely large volume of multimedia content in variou s forms on the Web, which keeps on rapidly growing. Another problem is that one part of that multimedia content is not annotated ; therefore it is very hard to find and reuse such content. The other part of multimedia content is described manually, hence th ose annotations may be too subjective or inaccurate, and may be lacking in formal semantics. This results in the need for efficient semantic annotation, so that computers and applications can easily process those metadata for reuse and retrieval of multime dia content. This paper presents ontologies in general as part of Semantic Web an d s pecific ontologies used for multimedia annotation . Comp arison of the most commo n ly used multimedia ontologies and their main features is provided in this paper. The se multimedia ontologies can be used for creating high qua lity and semantically rich multimedia annotations.
