Live Social Observatory: A platform for social media research

Prof Tat-Seng Chua, the School of Computing, National University of Singapore (NUS) Tue, 26/02/2013 - 10:00

Social network has become an indispensable part of social activities for many people. Most such people share their views, delights and life moments, as well as conduct online purchases on various types of social networks. In particular, a large amount of texts, images, videos and venue check-ins (known collectively as the user generated contents or UGCs) is shared in the process, which forms a rich part of social engagements and contents. The mining of UGCs enables us to study the various aspects of social habits and preferences of users. This talk introduces our research towards building a Live Social Observatory under NExT, a large-scale research center between NUS and Tsinghua focusing on research in extreme search. It first describes our efforts in crawling and managing the huge amount of UGCs, and their visualization. It then discusses our research on analyzing and structuring multi-source UGCs, and the mining of analytics for people, location, organization and events. The talk also describes our approach to index and retrieve the huge volume of social images, and the related research in inferring the often ambiguous users’ intention during media search.
