Research On Simulation Technologies Multi-agents Of The Rumor Spreading And Psychological Convergence Based On Artificial Society

The development of information network technology has made people life convenient, but also brings new public security threat to the society. The Internet has become a rumor and harm social security convenient channel of speech, buried under the public security events. Emergency management is an urgent need to research oriented to network public security incidents in the field of emergency management methods. In order to study the influence of information technology in society, the American rand corporation in 1991, puts forward the concept of "artificial society". It can provide a virtual labfor the social science research,also make the research of sociology through the experiment method.In this paper, by constructing a virtual network platform and establishingthe rumor spreading model with many psychological convergence Agent model, it simulates the spread of rumors on the Internet and network user community psychology of convergent evolution process. Through the simulation experiment results of the data analysis, it can get the basic rule of rumors spread psychological and change trend and network user groups. On the basis of the original simulation experiment set, we make control strategy to observe the effect of the control strategy and function, the spread of rumors to develop control strategy to provide scientific basis.Based on the above framework, this paper conducted the following research:First, this section builds a virtual network BBS based on complex network theory. The Internet as environment of spreading of rumors plays an important role in the modeling and simulation, but it confined to the level of the existing data mining technology, however, was unable to obtain information and analysis of the whole network node and the network topology. So in this article, through TSGN generation algorithm to produce structure similar to dating network BBS BBS, virtual network as rumours spread convergence modeling environment carrier.Second, rumors spread model was constructed in this section. In the complex system modeling method, rumors spread model is various, such as SI, SIS, SIR model. In this paper, on the basis of the SIR model is emphasized, transmission mechanism, the introduction of the mathematical model in the form of differential equation, and detailed introduced the modeling technology based on Agent SIR rumor spread simulation model. By constructing the virtual network of rumors spread on the BBS experiment, in order to verify the accuracy of the models.Third, this section builds the more psychological convergence Agent model. According to the way of convergence, the different structure, could be divided into field coordination and psychological convergence not smooth highlights two types of convergence. On mathematical model, simulation model of both are introduced in details. Introduction of anxious degree and the response value properties of two attributes as individual level model, and based on the spread of rumors, for in the network BBS user evolution regularity of the two attributes of convergence are expounded.
