We present a Web-based video annotation system named iVAS (intelligentVideo Annotation Server) that allows users to associate Internet videocontent with annotations. The system analyzes video content to acquirecut/shot information and color histograms. Then it automaticallygenerates a Web document that allows the users to edit the annotations.We also present two application systems based on annotations: videoretrieval and video simplification. An automatic evaluation method ofannotation reliability is also implemented.
