Research On Network Rumor Spreading Model Based On Heat Transfer

With the popularity of the Internet and the rapid development of information technology,it is more convenient for people to obtain information,and the speed and scope of information dissemination are greatly improved.In particular,with the popularity of Weibo,We Chat,Douyin and other social platforms,in this new era,"everyone has a microphone,and everyone is a commentator".It means everyone can create and forward some information content as they want.Compared with the traditional way of spreading word of mouth,social network platforms such as Weibo and We Chat have greatly increased the spread speed,scope of influence,and social harm of rumor information.Once the rumors spread,they may endanger the safe development of the economy and society,cause people to panic,and affect social stability.Therefore,in social networks,analyze the spreading process of rumors,construct a rumor spreading model that conforms to the social status quo,explore the key factors that affect the spread of rumors,and provide more effective countermeasures to curb the spread of online rumors.Based on the relevant theoretical knowledge of heat transfer,this paper studies the spreading law of rumors from different aspects,establishes a rumor spread model that conforms to the actual law of society,and explores the influence of different influencing factors on the spread of online rumors.First of all,this article analyzes the thermal radiation process of objects,and compares it with the rumor spreading process,and discusses the related factors affecting the Internet rumor spread.Based on the theory of thermal radiation,the Thermal-radiation dispersion model is constructed.In this model,the individuals in social networks are divided into four states: the state of ignorance,the state of activity,the state of hesitation,and the state of blocking,and according to the energy absorption and release in the individual,the transition rules between each state are formulated.At the same time,the influence of individual activity,individual authority and rumors attraction on the evolution of rumors is considered.Then,numerical experiment simulation was carried out through Matlab to analyze the influence of each parameter on the evolution process of the rumor explosion.The experimental results show that the greater individual activity and the attraction of rumor,the more it will promote the spread of rumors.Secondly,this article analyzes the spreading process of network rumor and the heat conduction process by analogy,and compares the temperature change during the heat conduction process to the change in the popularity of network rumor,and the spreading influence of rumor spreaders in social network is analogous to the "heat conduction" phenomenon of rumor spreading.By analyzing the energy change of each part of the whole system,the heat conduction propagation equation of rumor and the heat conduction rumor propagation model is established.At the same time,the influence of rumor event importance,individual anti-interference ability and Propagator’s propagation intensity on rumor diffusion equation is considered.The experimental simulation through Matlab shows that the higher the importance of the rumor event,the weaker the individual’s anti-interference ability,and the greater the spread of the rumor spreader,it is easier for rumor information to spread in social networks,and based on the above research,it is pointed out countermeasures to prevent and control rumor.In summary,this article explores the influencing factors of the diffusion and spread of online rumors in social networks,and constructs Thermal-radiation diffusion Model and Heat-conduction spread Model.Then proposes prevention and control strategy for rumor.The research results of this article have innovated the research ideas for the research on the spread of network rumor,and provided new ideas for the research and development of rumor in the future.
