—Today, social networking has become a popular
web activity, with a large amount of information created by
millions of people every day. In this paper, we focus on Sina
Weibo, a rapidly growing microblogging platform, which
provides a large amount, diversity and varying quality of
content. Our research is from a regional perspective, and focus
on the information propagation process. By measuring the real
behavior of the user’s blog sharing, we construct the network
model of information follow and forward. We found that a
small group of nodes can cover the most of the communication
behavior of the information propagation. Then, we proposed a
new method to rank the users, and proposed an evaluation
based on real measurement coverage. Compared to similar
algorithms to verify its effectiveness and accuracy.
—Information propagation, microblog, social
network, user identify.
