Social Media Analytics

Social Media pervades much of our daily life and has significant socio-economic impact around the world. Several interesting research issues arise in this context. What is the nature of information propagation through this medium? How does information spread virally? Who spread that rumor? What are the human dynamics in Social Media and how does it impact information consumption?
