Design And Simulation Analysis Of Mobile Social Network On The Basis Of Multi-Agent System Theory

With the rapid development and popularity of mobile Internet,the number of mobile Internet users increase year by year.Mobile social network has integrated into daily life of network users.It enhances the user experience and diversifies the communication between people.At the same time,it brings new changes to the information dissemination.On the basis of analyzing the influence factors of mobile social public opinion,this article introduces the Bayesian network and multi-agent method to set up the model of mobile social communication from quantitative point which provides a scientific basis for guiding the social public opinion of mobile.At first,this article sorts out the literature about network public opinion.the author found there are a lot of platforms of public opinion which is also very decentralized;Besides,the existing researches take the impact of single external environment into account,ignoring the effects of mobile social platform and traditional media.Wha’s more,there are few articles analyzing the psychological factors of Internet users which cannot describe the psychological factors of Internet users as a result.In response to these circumstances,the author studies the network public opinion platform on the focus of mobile social network.Based on the summary of the main influencing factors of mobile social networking,this paper builds the public opinion model of mobile social platform by Bayesian network.However,due to the asymmetry of information,users who are ready to make decisions will be affected by the group effect which means the herding effect.Therefore,the model is further modified on the basis of herding effect.The model is further extended by traditional media.On the basis of theory,a multi-agent mobile social network simulation model is constructed which includes subject and its attributes at the same time.Moreover,by setting the rules of interaction between the main body and using multi-agent simulation software Netlogo,the author starts to find the public opinion evolution mechanism on mobile social platform.It turns out that the model is reasonable and matches the actual dissemination trends of public opinion.What’s more,the results of simulation show that: Opinion leaders is still leading the spread of mobile social public opinion;Furthermore,once the proportion of water army increases,the heat of public opinion will increase and the duration of public opinion will become longer accordingly.Traditional media promotes the spread of mobile social,however,when the public opinions of traditional media are different from those of mobile social network,traditional media can effectively slow down the spread of public opinion trends.
