Context-Aware Media Personalization

Personalizing the user's media experience based on his changing context, which we call context-aware media personalization, is an important challenge. Unlike traditional personalization systems that merely based on user preference, context-aware personalization system takes context information ranging from user preference and situation to device/network capability as input for both content and presentation recommendation. This paper introduces the generic architecture of context-aware media personalization, and presents solutions for the key techniques of it, which are MPEG-7 based media description model and ontology based context representation model, context aggregation, reasoning, and learning, media recommendation, and media adaptation.
