Research On Dynamic Evolution Of Network Public Opinion Based On Bounded Trust Model

In recent years,the scale of Internet users in China has been increasing,and the Internet penetration rate is also steadily increasing.The popularity of the Internet has increased the role of the Internet in social development.Different from the traditional lyric information based on newspapers,radio broadcasts,television and other media,in the current network environment,the source of information is gradually diversified,and online public opinion events are often �amplified� by the network,which will definitely be safe for the network.The impact of people's life and social stability,the prediction and monitoring of online public opinion has become one of the inevitable tasks of relevant departments.The simulation study of the evolution of public opinion will give the relevant departments a prediction of the trend of changes in public opinion,grasp the direction of public opinion,and provide technical support in response to sudden public opinion events.Insufficient research on the dynamic evolution law of network public opinion at this stage,this paper first summarizes the research on network public opinion and public opinion evolution,social network analysis,and explores the feasibility of combining social network analysis and other theory with bounded trust model.Sexuality,with Weibo platform as the research subject,taking real network events as the research object,based on the classical bounded trust model,combined with the characteristics of Weibo,proposed an improved dynamic HK model.On this basis,this paper selects the microblog platform "Tianjin Binhai New Area Explosion Event" as the research case event,and simulates the evolution of Tianjin explosion event through Matlab software according to the data preprocessing-model operation-the result comparison process.It demonstrates the rationality of model construction.Finally,the simulation program is used to explore the influence of government intervention on the evolution of public opinion,and give reasonable suggestions.
