Research on the simulation model of public crisis internet information diffusion

摘要

The paper analyzed the connotation about public crisis internet information diffusion, and built a simulation model of that. On the basis of choosing the platform of simulation model, the settings of simulation experiment were discussed. By changing the parameters, it analyzed different results and reasons, and at last reached 5 valuable conclusions, that is, First, public crisis internet information diffuse very fast. Second, public crisis internet information diffusion has inherent regularity. Third, group polarization phenomenon exists in public crisis internet information diffusion process. Fourth, the credibility of the original information has important impact on the result of public crisis internet information diffusion. Fifth, the time government publishing crisis information and the supervision and guidance of government are important to diffusion results.
