The POLYSEMA MPEG-7 Video Annotator

— Annotation of multimedia content with metadata is regarded as a key issue for efficiently handling such content. MPEG-7 is a major standard that has been developed for this reason, supporting the description of both low- and high-level multimedia content features. Low-level feature annotation may be automated in many ways, contrary to high-level annotation which is a more complex task that requires human intervention. Therefore, high-level semantic annotation needs to be simplified as a process, mainly through annotation tools. In this paper we describe such a tool, which facilitates expressive video annotation process by combining MPEG-7 metadata and semantic web ontologies.
