Special Issue on Social Media as Sensors IEEE Transactions on Multimedia


SUBMISSION DUE DATE: 7-September-2012

Web 2.0 applications and social media have transformed the Web into an interactive sharing platform where users upload data and media, comment on and share this content within their social circles. Each content item is associated with an abundance of metadata and related information such as location, tags, comments, favourites, access patterns and logs etc. At the same time all this information is implicitly or explicitly interconnected based on various properties such as social links between users, groups, communities, etc. These properties transform social media to data sources of an extremely dynamic nature that reflect topics of interests, events, and the evolution of community opinion and focus. Social media offer a unique opportunity to structure and extract information and to benefit multiple areas ranging from computer vision to sociology and marketing.
