Research On The Network Simulation And Information Dissemination Model Of Micro-blog

With the development and evolution of online media, micro-blog has become an important platform for information exchange and changed the traditional way.Dissemination of information content in micro-blog is based on the follow relationship network between. Mining and research about micro-blog information dissemination law can help us understand the essence of information exchange, and provides a theoretical basis on monitoring public opinion. In this paper, we researched in-depth the network topology of micro-blog and the model of micro-blog information dissemination based on the theory of complex network.First of all, The dissertation improved the BA scale-free network model, introduced the mechanism of friend recommendation and natural growth in the model, then built the evolution model of micro-blog network, And obtained the micro-blog user follow relationship data, we found that the improved network and the micro-blog network both had the characteristic of scale-free and small-world by analyzed their topology; Secondly,the dissertation designed four different nodes states namely susceptible state, infective state, hesitating and recovered states in propagation model according to characteristics of the micro-blog information propagation, and formulated the rules of transition of these four nodes; Finally we simulated the information dissemination process under different parameters with micro-blog network and improve network as background network.Through compared and analyzed the simulation results of information dissemination and topological properties of micro-blog network and improved network, we verified the effectiveness of the improved model and summarized the basic law of micro-blog information dissemination according to the simulation results. Research micro-blog network structure and information propagation in micro-blog is conducive to monitor the development direction of public opinion information, it can also be time to stop the spread of information and network viruses and other in micro-blog network, and provide decision support to government to monitor and deal with the information propagation.
