Human as Real-Time Sensors of Social and Physical Events: A Case Study of Twitter and Sports Games
Real-Time Sensors Social Physical Events Twitter Sports Games Case
font style='font-size:12px;'>
2011/9/14
In this work, we study how Twitter can be used as a sensor to detect frequent and diverse social and physical events in real-time. We devise efficient data collection and event recognition solutions t...
Predictability of extreme events in a branching diffusion model
