Research On Evolution Mechanism Of Group Public Opinion Based On Influence Among Communities

The rapid development of the information age,such as WeChat,Weibo,Tik Tok,Fast hands and other social media has gradually occupied a large part of our lives,becoming an important way for us to communicate and express our views,bringing social life to our lives.Convenient and fast,it also facilitates the emergence and outbreak of public opinion.In recent years,because of the Internet public opinion,the adverse effects on society have appeared frequently.In this context,the generation of network public opinion in the information age,the evolution law,and the dynamic control and system of the government and enterprises on the Internet public opinion Analysis has strong practical significance.Based on the relevant research results at home and abroad,this paper integrates the research methods of complex network,modeling analysis and computer simulation,and proposes a mechanism of public opinion evolution based on the influence of inter-community,through the influence of the community within the group.Therefore,the final evolution model of the group is obtained,and the model is simulated and analyzed.The main contributions of this paper are as follows:1.Through the analysis of the classic public opinion evolution model Deffaunt model,combined with the reality,the Deffaunt model is improved,and the node intimacy parameter is added to make it more in line with the real-life public opinion evolution model,and the model is simulated through simulation.The practicability is verified,and the simulation results prove that the model has good applicability.2.Innovatively put forward the issue of inter-community influence.As an important component of social network,the current research on associations mostly focuses on community division.This paper gives a kind of association to the characteristics of interaction between communities.Interinfluence calculation method,which abstracts the community in the network into a community node,and simplifies the influence relationship between one-to-many,many-to-one and many-to-many into a one-to-one relationship.The measurement of inter-institutional influence further provides theoretical support for the evolution of group public opinion.3.On the basis of the improved public opinion evolution model in the community,the algorithm of inter-community influence is integrated,and the public opinion evolution model based on the influence of the community is proposed.The computer simulation experiment is carried out,and the evolution of the paradox is explored by modifying the different parameters in the experiment.The key factors in the experiment,the experimental results show that the model has certain innovation,and has played a certain guiding significance for the supervision of public opinion in government departments.
