Research On The Mechanism Of Microblog Public Opinion Evolution Based On Multi-agent

With the rise of the network society and the sharp increase in the microblog users,microblog public opinion has become a frequent social phenomenon which cannot be ignored.By aggregating the opinion,microblog public opinion can form a powerful social force,and a profound social impact.In this background,understanding the formation conditions and environment of microblog public opinion,studying the development rule and influence factors of microblog public opinion,has important practical significance.O n the basis of combing the domestic and foreign related research results,the integrated use of literature review method,interdisciplinary research and computer simulation,this paper analysis the general evolution of microblo g public opinion.Microblog public opinion evolution is a process of a multi-agent collaboration,with small world properties.Microblog in the community related diversification by focusing on the agent forward,push message self-organized coordinated manner to promote the development of the microblog public opinion evolution.In this article,by combing the microblog public opinion,dynamic system model of infectious diseases and multi-agent simulation methods,using multi-agent modeling for the microblog public opinion analysis,and to quantify the evolution process of multi-agent simulation to a certain extent to the evolution of simulation.The main research content of this paper is:(1)this paper discusses the connotation and constituent elements of the microblog public opinion,and has proved its propagation path,subject features for the next microblog public opinion analysis lays the foundation.(2)through the understanding of the connotation of the microblog public opinion evolution,introducing the theory of self-organization evolution of dynamic process of microblog public opinion.(3)considering the microblog public opinion in the heterogeneity of the agent,this paper analysis the interaction and the mutual influence between different subjects factors and weights,using the method of multi-agent to set rules of interaction among the subjects,probability of infectious disease SIR model more suitable for the improvement of microblog public opinion evolution.(4)using multi-agent simulation software Netlogo for microblog subject interaction simulation in the course of the evolution of public opinion,from the main body of interaction and mutual influence the results reflect the dynamic process of microblog public opinion evolution.(5)to select 2015 "8 · 12 Tianjin extra-large fire explosion accidents" as a sample case,through data collection,verifies the correctness of the multi-agent simulation results and objectivity.By analysis of the dynamic evolution process of microblog public opinion,t he use of multi-agent simulation software of the simulation,through a single change the behavior main body property parameters,this paper analyze its influence on the microblog public opinion evolution,inductive conclusion microblog public opinion evolution general rule,for the relevant government departments to provide some advice possibility of microblog public opinion supervision.
