Integrating Interactive TV Services and the Web through Semantics

摘要

Interactive TV has started to penetrate broadcasting markets, providing a new user experience through novelservices to subscribers and new revenue opportunities for companies. Personalization and intelligent behavior;such as proactive content delivery are considered key features for the services of the future TV. However, mostof the work in this area is limited to personalization of electronic program guides and advanced programrecommendation. In this article, the authors adopt a more horizontal approach and describe the applicationof concepts, practices and modern Web trends to the TV domain in the context of the POLYSEMA platform.A key characteristic of this approach is the formal modeling of multimedia and user semantics that enablesnovel TV services. Specifically, Semantic Web methodologies are employed (e.g., ontologies and rules) whilecompatibility with the MPEG-7 standard is also pursued. The paper describes the overall architecture of theplafform, provides implementation details and investigates business issues.
