Abstract

The Web is progressively becoming a multimedia content delivery platform. This trend poses severe challenges to the information retrieval theories, techniques and tools. This chapter defines the problem of multimedia information retrieval with its challenges and application areas, overviews its major technical issues, proposes a reference architecture unifying the aspects of content processing and querying, exemplifies a next-generation platform for multimedia search, and concludes by showing the close ties between multi-domain search investigated in Search Computing and multimodal/multimedia search.
