A model for studying public opinion hotspot growth regulation in microblog network

Regarding the problem of microblog growth regulation of net-mediated public sentiment in the propagation process, a complex-network-based modeling approach was proposed. Taking microblog as a research object, by using the approach of growing, adding edge and random adding edge to reflect the characteristics of user's behavior and microblog public opinion dissemination, a microblog net-mediated public sentiment growth mode was built. By using Matlab toolkit, a simulation model was built. Through running this simulation model according to different network scale experiment cases, for example, setting parameters of the initial nodes size and the random adding edges, diagrams could be layout, that illustrating network, degree distribution and probability distribution. Simulation results validated the model's feasibility for studying network public opinion hotspot growth regulation.
