Network public opinion can quickly form a network of public opinion, and promote the dissemination of information fission, with a strong interaction and effectiveness. In the case of “A girl suffered attacks in a Yitel”, we construct network propagation diagram by ucinet software and research the structural characteristics of the network public opinion propagation network based on Sina micro-blog, and the whole structure of the propagation network and the key nodes are measured. The results show that the key nodes in public opinion network propagation has a high ability to spread, so we can control the velocity of micro-blog public opinion through affecting these key nodes.
