Audiovisual querying and browsing based on the semantic views model

In this paper, we describe a user-oriented audiovisual retrieval model called the Semantic Views Model and its application to querying and browsing of audiovisual data described by MPEG-7. The Semantic Views Model was designed based on a user study in a professional TV production and archiving environment. Its goal is to provide a common and simple structure for the description of various audiovisual characteristics which are needed during querying and browsing. We present a query language and a hypermedia model, which are both designed based on the Semantic Views Model, and we describe their implementation to retrieve audiovisual data described by MPEG-7.
