We will present content analysis, content description, multimedia ontologies and multimedia deployment results based on our research. Content analysis research is concentrated on visual video analysis, from low level features up to semantically meaningful high level features. Content description topics include MPEG-7 related metadata modelling and tools for the creation and validation of metadata descriptions (http:www.joanneum.at/uploads/tx_publicationlibrary/img3052.pdf, http:www.joanneum.at/uploads/tx_publicationlibrary/HAW-2007-OEGAI-EN.pdf). Secondly we present and demonstrate our video browsing suite, which supports the clustering of various video content features, and provides for summaries of the content (http:www.joanneum.at/uploads/tx_publicationlibrary/BAW-2006-TRECVID.pdf) Finally, we will focus on media semantics from multimedia Ontologies (NM2, MEPCO, COMM) to deployment issues of multimedia metadata on the Web (http:sw.joanneum.at/rammx/).
