Abstract: The emergence of the Interactive Digital TV (iDTV) is improving the transmission quality and making available new features and services to the user. With the advent of digital convergence between TV and web platforms, new proposals of semantic organisation of content are being developed, introducing concepts of Semantic Web and knowledge representation that allow semantic description of metadata content through ontologies. This paper proposes a component for finding domains and expansion of multimedia metadata in broadcast DTV based on the Semantic Web concepts and analysis of lexical and semantic similarity, integrated with knowledge TV platform.

Keywords: interactive digital television; iDTV; Semantic Web; ontologies; domain discovery; domain expansion; multimedia metadata; digital TV broadcast; knowledge representation; semantic description; knowledge TV platform; ontologies; lexical similarity; semantic similarity.
