Information Dissemination Mechanism In Mobile Social Network:Model Building And Simulation

With the rapid popularization of mobile terminal devices,mobile social networks have gradually become an integral part of people's daily lives,and the number of users has continued to rise.The influx of a large number of new users and the frequent and close connection between them have made mobile social networks the main channel for people to communicate and disseminate information,which has profoundly affected information governance,knowledge sharing,and user behavior.Studies have shown that researching mobile social network information dissemination mechanisms from the perspective of a single network relationship structure,the attributes of traditional social networks and dissemination nodes,and dissemination subjects is a hot topic at the moment.However,mobile social networks in reality actually contain both strong and weak connections,rather than a single network structure;at the same time,existing research also ignores the key subject of information dissemination-user attributes and the relationship between information and information.Mechanism of propagation resonance.In order to explore the impact of strong and weak relationships,user attributes,and information transmission resonances on mobile social network information transmission,this article conducts research from the perspectives of complex networks,user attributes,and information transmission resonances.Three perspectives constitute a complete information transmission process,including The three elements of information dissemination: people,network relationships,and information can fully reflect the information dissemination mechanism.The details are as follows.First,the research is carried out from the perspective of a complex network.Based on the SIR model,the correlations that can reflect the strong and weak relationships that affect information dissemination through the introduction of easy-propagator comment coefficients,latent conversion rates,transmission conversion rates,and immune commentary coefficients are introduced Influence factors,build a SEIRC model;secondly explore from the perspective of user attributes,introduce user characteristics such as user similarity,initial node user influence,and user information frequency sensitivity to build a SEIRC improvement model;finally analyze from the perspective of information propagation resonance Based on the physical stochastic resonance model,the existing information weight,regional heat,existing information heat,information timeliness,and original information influence were introduced to establish the information propagation resonance model.Through simulation experiments to verify the correctness of the SEIRC model,the SEIRC improved model,and the information propagation resonance model,the influence of the relevant factors on the information dissemination from the three above-mentioned research perspectives is analyzed.According to the simulation results,the influence of related factors based on the perspective of complex networks on mobile social network information transmission is as follows: user relationship strength,transmission conversion rate,and latent conversion rate are directly proportional to information transmission rate;immune coefficient is inversely proportional to transmission rate;easy to spread Increasing the comment coefficient and the comment coefficient can reduce the number of immune nodes and improve the efficiency of information transmission.The influence of related factors based on the perspective of user attributes on information dissemination of mobile social networks is as follows: user similarity and information dissemination efficiency are proportional;initial node user influence and information dissemination efficiency are proportional;user information frequency sensitivity and information dissemination efficiency Inverse relationship.The influence of related factors based on the perspective of information transmission resonance on the information transmission of mobile social networks is as follows: the existing information weight is proportional to the information transmission resonance;the regional heat and the existing information heat positively affect the information transmission resonance;the information timeliness reaches a certain level The saturation point will suppress the occurrence of information transmission resonance;the original information influence is proportional to the information transmission resonance.Based on the above simulation results,this paper proposes management proposals for improving the effect of information dissemination,with a view to providing a certain reference for government's public opinion governance and corporate marketing strategies.
