Now that text-based search engines have begun to give way to content- and context-aware engines, advanced network infrastructures are starting to emerge. These infrastructures are capable of end-to-end ubiquitous transmission of multimedia content to any device, fixed or mobile, on any network, wired or wireless, at any time. This book is a collection of expanded papers presented at the 2007 2nd International Workshop on Semantic Media Adaptation and Personalization. It explores recent and new developments in the field of semantic media adaptation and personalization. Topics discussed include the challenges of collaborative content modeling, video adaptation, information retrieval techniques for semantic media adaptation, and podcasting.
