Research On Social Network Public Opinion Transmission Mechanism From The Perspective Of Coupling Network

With the widespread popularity of mobile terminals and the rapid development of various types of social networks,netizens will transfer information between different social networks.Therefore,research on the dissemination of public opinion information in the context of social networks,especially exploring social networks The spread of public opinion information across the Internet has important practical and theoretical significance.This article explores the types and characteristics of public opinion communication in social networks,studies public opinion communication in a social environment from three perspectives: single-layer microblog network,double-layer We Chat network,and Weibo and We Chat coupled network,and build a corresponding public opinion communication model.Specifically,the research content of this article mainly includes the following three aspects:Firstly,in order to study the public opinion transmission mechanism of single-layer Weibo network,a public opinion communication model of Weibo network based on the improved SIR model was proposed,and a directed scale-free network was designed based on the microblog network topology.Information interaction mode has improved the infection rate and conversion rate.The experiment compares the process of Weibo public opinion transmission under different positive and negative factors,infection rates,conversion rates,immune rates,and derivation rates;Secondly,in order to study the public opinion transmission mechanism of the double-layer We Chat network,a public opinion transmission model based on the double-layer We Chat network was proposed,which divided the infected people into two categories of people: contacting users and friends to obtain public opinion information and reading We Chat public accounts,Simulate a two-layer We Chat topology based on the public account and the circle of friends,and use the information interaction mode of We Chat network to improve the infection rate.The experiments compare the positive and negative factors,conversion rate,and immunity ratio of different We Chat layers Layer We Chat public opinion dissemination process;Finally,in order to study the social network and the transmission process of public opinion between Weibo and We Chat networks,a social network public opinion propagation model based on a coupled network is proposed.The scale-free directed network and the BA network are used to simulate the Weibo network and We Chat network environment respectively.The coupling network carrier is designed through specific connection relationships.Based on the SEIR model,the user 's communication psychology is fully analyzed,and the individual Features such as interest decay effects and memory effects.The simulation results show that the constructed two-layer social network public opinion transmission model can better reflect the process of public opinion communication in real life.The interaction between users on multi-layer social networks accelerates the flow of public opinion information and expands the influence of public opinion information.The control of inter-layer propagation thresholds is the key to managing the spread of public opinion in multi-layer social networks.
