In the Informedia Digital Video Library, the production of the meta-data supporting the library interface is automated using techniques derived from artificial intelligence (AI) research. By applying speech recognition together with natural language processing, information retrieval and image analysis, an interface has been produced that helps users locate the information they want and navigate or browse the digital video library more effectively.
