The emergence of user-centric multimedia applications on social networks has been instrumental in the creation of a new form of “social” media – created using highly accessible and scalable publishing technologies for sharing via the internet. This timely text/reference presents the latest advances in various aspects of social media modeling and social media computing research. Gathering together superb research from a range of established international conferences and workshops, the editors coherently organize and present each of the topics in relation to the basic principles and practices of social media modeling and computing. Individual chapters can be also be used as self-contained references on the material covered. Topics and features: Presents contributions from an international selection of preeminent experts in the field Discusses topics on social-media content analysis, including social-image tag analysis and ranking, tag-based social image search, analysis by combining multimodal features, and multi-label social-image annotation Examines social-media system design and analysis, covering mechanisms for incentivizing contributions, analysis of users and online behaviors in video sharing portals, and visual analytic tools for event analysis Investigates access control for privacy and security issues in social networks Describes emerging applications of social media, for music recommendation, automatic image annotation, and the analysis and improvement of photo-books This unique text is a must-read, must-use tool for software developers, researchers and graduate students working on multimedia, web search, data mining and machine learning, and related disciplines. High-level managers and professional engineers interested in emerging social media modeling and computing technologies will also find the book to be an invaluable reference. Dr. Steven C.H.
