An Empirical Study on the Efficiency of Information Propagation in Online Social Network

In this paper we measure the efficiency of information propagation in online social network from two metrics: the speed and the width. We collect data from Sina microblogging website, and analyze the relation between the speed as well as width and the number of fans as well as interested by the method of correlation analysis. The analysis results show that both the speed and the width of information propagation are highly correlated with the number of fans, but they are not strongly correlated with the number of interested.
