Abstract: The paper investigates the formation and spread characteristics of the public opinion from the perspective of network formation and evolution. This paper studies the topological structure characteristic of WEB2.0 peer production virtual community based on WEB2.0 using complex network model. The result shows that the out-degree follows power law distribution and the in-degree follows two-stage power law distribution. It also shows that the contributors behavior with strong heterogeneity. The paper uses the improved LP link prediction method to sort and analyze the potential link on WEB2.0 virtual community. As a result, in second-order path case, the object of attention by those concerned plays a more important role than other ones. The study of the case of third-order path has reached a similar conclusion; the indirect interest and the direction have a greater impact on public opinion propagation.
