Use Cases Scenarios

This chapter presents the research approaches to extracting, deriving, processing, modeling, using and sharing the semantics of multimedia. It motivates these approaches with three selected use cases. The ‘photo use case’ motivates issues around finding and sharing photos on the Web. In order to achieve this, a semantic content understanding is necessary. The issues range from administrative metadata to describing the content and context of an image. The ‘music use case’ addresses the audio modality. It discuss a broad range of issues ranging from semantically describing the music assets (e.g. artists, tracks) over music events to browsing and consuming music on the Web. The ‘video use case’ covers annotation of audiovisual content in the professional audiovisual media production process. The use cases introduce the challenges of media semantics in three different areas: personal photo collection, music consumption, and audiovisual media production as representatives of image, audio, and video content.
