Multimedia analysis and annotation requirements for the semantic web

The Semantic Web is about adding formal structure and explicit semantics to web content for the purpose of more efficient information management and access by both humans and computers. Through the use of machine understandable semantics, web resources become much easier and more readily accessible. Populating the Semantic Web with multimedia metadata requires for appropriate technologies to support both the analysis (metadata extraction) and the annotation (metadata creation) processes. The media- and content-specific semantics of multimedia resources pose great challenges in terms of capturing and manipulating the two layer semantics given the available knowledge representation formalisms. The Knowledge Web project, advancing ontology technology research efforts and ensuring transferring the semantic web from academia to industry, has provided solutions to some of the most challenging multimedia related problems.
