Talk: Ruixi Yuan, "Online Cooperation/Competition Dynamics"

November 23, 2010




The Internet presents rich opportunities to conduct large-scale social behavior and information diffusion research. We present two studies based on large scale online data.
In the first study, cooperation and competition dynamics from online gaming communities were analyzed and a discrete model was developed for the gaming system. In the second study, an epidemic information propagation model was developed to model the topic propagation in the blogspace. We demonstrate its effectiveness by comparing to data collected from popular Chinese blog sites.
Professor Yuan willl also introduce some recent research progresses in the area of topic emergence and social networks.
