Fission mode of information transmission in the Microblog network presents a challenge to the existing public opinion diffusion model. In order to depict the mechanism of the public opinion transmission in the Microblog network, this paper proposes a topic evolution model based on the complex networks and infectious disease dynamics theory. The model takes the directed scale-free network as the carrier, which synthetically considers the characteristics of topic propagation and its influence factors. In addition, the research performs simulation analysis, of which result mirrors the topic evolution process from common topic into hot topic, and verifies its validity.
Keywords:Microblog network; topic evolution; hot topic
