Evolutionary Game Model of Information Interaction in Social Network

摘要

Nowadays, the majority of common people are connected by a variety of online social network interaction platforms. How can we build a convincing theoretical model to describe viewpoint evolution embedded in the user behaviors of information interaction is still an open question. We apply evolutionary game to analyze user behavior aspects of information interaction to reveal basic rules and features of opinion interactions in microblog. Wo have divided the users into three different kinds of players with respective payoff, and the evolutionary game model simulates a group of individuals participating in a discussion, aiming at persuading opponents into an agreement. The experiments on a realistic dataset show that opinion leaders in microblog are a group of people who will stick their own mind strongly, chatters are easily persuaded since they may just want certain information to be known, while general people keep staying in the neutral zone.
