Research On Simulation And Governance Of Network Public Opinion Communication Model In Dual-information Competition

In recent years,with the development of Internet technology,China has entered the era of "We Media".A variety of social applications,such as Douban and Weibo,have emerged in an endless stream,opening up new platforms for people to share and communicate information,and “sharing news anytime and anywhere” has become a true portrayal of People's Daily life.But at the same time,accompanied by the emergence of network public opinion events.When online public opinion events occur,they are usually accompanied by a variety of information dissemination.For the same event,different information is often derived due to different concerns.Besides the diffusion of original information,there is also a process of information feedback such as comments.Therefore,there is a large amount of information in the network to grab the attention of the Internet users,forming a competitive relationship between information.This kind of competition is more likely to increase the difficulty for the government to deal with,further trigger the overreaction of the public,and lead to the evolution of public opinion events.Based on this,this paper studies the evolution process of public opinion information competition.This paper first summarizes the research status and achievements of public opinion information dissemination at China and abroad,expounds the related theories and methods,introduces the main research contents and methods and the overall chapter arrangement;Secondly,it combs the relevant theoretical research,including the concept and communication characteristics of network public opinion,the concept and characteristics of network public opinion information,and the classical infectious disease model;Then,from the perspective of information competition,this paper studies the case of factual public opinion.By crawling the microblog data of the event of “Chongqing Bus falling into the river”,this paper analyzes the information competition relationship in each stage of the public opinion communication process,summarizes the synchronous and asynchronous mode of information competition,and analyzes the guiding and governance role of public opinion events from the government level;Then,based on the previous research,this paper constructs the SH2 IR model of binary information competitive dissemination,and analyzes the impact of information contact rate,hesitation conversion rate,dissemination conversion rate and information replacement rate on information dissemination under two scenarios of information synchronous release and asynchronous release by simulation;Finally,on the basis of SH2 IR model,this paper subdivides the two kinds of information into formal information and informal information,constructs a competitive evolution model for formal information and informal information,and sets two governance strategies of the government through numerical simulation to analyze the impact on the evolution results of public opinion,so as to obtain the best governance strategy for the interaction process of formal and informal information in public opinion events,which can provide reference for the government The government provides suggestions and Countermeasures to manage public opinion.
