Abstract: In this paper we present first results of the implementation work on the exploitation of MPEG-7 descriptors within the MISTRAL system, which aims at enhanced procedures for semantic annotation and enrichment of meeting-related multi-modal data. As the system consists of several specialised units, the focus is set on its Semantic Applications Unit (SemAU). First, we give a short overview on the MISTRAL system as well as explain the overall architecture and some functional modules of SemAU. Then, emphasis is placed on the role of MPEG-7 metadata within the MISTRAL system as standardised bridge between its units and as basic standardised input for SemAU. Finally, some insights are given into the current development stage of two user-centred applications of SemAU. These applications manage semantically enriched multi-modal data in order to enhance its retrieval and visualisation.
