Research On Internet Rumor Propagation Model Based On BK Seismic Model

The popularity of the Internet and the rapid development of social networks have broken the limitations of space,time and region for users to publish or obtain information,and changed the ways and means of information transmission among users.It is more convenient,anonymous and instantaneous to spread rumors,which makes it easier for rumors to breed and erupt in a large scale in a short time.Due to the characteristics of wide range,great influence and strong harm,Internet rumors have stronger destructive power and negative effect,which can easily cause public opinion,pollute the social environment and threaten social security.Therefore,in order to effectively control rumor propagation and reduce its harm,it is necessary to conduct a systematic study on the influencing factors and evolution laws of rumor propagation,build a rumor propagation model simulating real situations,and formulate effective prevention and control strategies based on theoretical basis.Combined with the BK seismic model and related theories,this paper establishes the corresponding internet rumor propagation model,deeply analyzes the influence of various factors on the rumor vibration process,and discusses the rumor propagation law.The main contents are as follows:Firstly,this paper deeply analyzes the process of block vibration and its influencing factors,compares the process of earthquake with the process of rumor propagation,and puts forward the four periods of rumor vibration process and the main influencing factors.Furthermore,the BK seismic model,which is used to simulate the earthquake process,is applied to the study of rumor propagation.Based on the changes of forces in the process,the influence of the changes of relevant parameters,such as users,rumors and environmental attributes,on the rumor force and user resistance is considered,and the rumor vibration model(ERP model)based on BK seismic model is constructed.In the model,the analysis of individual stress distribution from the microscopic view,proposed user individual critical sliding condition,from a macro point of view,the analysis of the whole stress distribution analysis of the whole internet rumor force vibration scale change and rumors,to explore the related parameters on the critical sliding condition,the entire internet rumors of force and the influence of rumor vibration scale.Through the simulation experiment,it is concluded that the higher the importance of rumors,the worse the event environment,and the more rumor information flowing into the network,the greater the influence of rumors.Reducing the initial influence of rumors and the propagation rate of users can effectively control the rumor propagation scale.Secondly,the introduction of user interaction mechanism,according to the individual critical sliding condition in the ERP model of social network users in the category division,considering the real spread rumors spread existing user attributes in the process of inner changes,rumors information effect to define the parameters of vibration resistance is established considering the user state rumors spread model(UERP model).The dynamic evolution rule of rumor propagation is obtained by simulation analysis from three aspects: whether the slider updates the status,the speed of government public relations and the value of seismic parameters.The experimental results show that promoting slider status updates,speeding up the speed of government public relations,and decreasing rumor vibration rate,rumor acceptance rate and increasing rumor seismic resistance rate can suppress rumor propagation.At the same time,this paper verifies the rationality and effectiveness of the model through model comparison and empirical analysis.Finally,based on the two models proposed and the experimental simulation results,the corresponding rumor prevention and control strategies and suggestions are put forward from the four stages of rumor propagation process(static period,sliding period,vibration period and fading period)and the three types of subjects involved in the rumor propagation process(users,media or platforms,and governments).In conclusion,based on the BK seismic model,this paper establishes an internet rumor propagation model from the two aspects of force and user status,explores the influence of relevant factors on rumor propagation,and summarizes the rules of rumor propagation.This study broadens the research ideas of rumor propagation,provides important theoretical support for further understanding and mastering the rumor propagation laws in actual social networks,and is helpful for analyzing and formulating rumor prevention and control strategies in actual social networks.
