Now, user can watch program contents selectively through IPTV service at anytime. User, however, has the difficulty in searching the desired program contents because of inefficient retrieval interface and content annotation of IPTV. Our search and ranking method suggests broadcasting programs relevant to the queried broadcasting program based on their semantic knowledge structures, which describe core concepts and relationships extracted from the contents of broadcasting programs. Program search technique is performed based on the revised tf*idf. We define four ranking measurements, topic label coverage, topic completeness, relation complexity, and topic density, to rank the retrieved programs according to their ranking scores.
