报告题目：Social Media Analytics for Study of Public Events, User Mobility and Wellness
Many people and organizations use multiple social networks to share their views and moments on many aspects of their activities. The mining of such contents along with their metadata (collectively known as the user generated contents or UGCs) enables us to study the various aspects of social habits, views, concerns and preferences of users. This talk describes the design, implementation and application of a live social observatory system. It incorporates an efficient and robust architecture to continually crawl live social streams from multiple social network sites and automatically analyzes theses streams to mine social senses, phenomena, influences and mobility trends. The Observatory can be used to study the evolution of public events, like an election, or personal events, like the health and activity timelines, demography and mobility of users. This talk describes a framework for such applications, and points towards long term research on collaborative live social observatories and the sharing of analytics.
