| With the rapid advancement of Internet technology in recent years and the popularity of smart devices on the mobile side,online social networks have developed rapidly and are closely integrated with our lives,learning and work,changing people's lifestyles.Human society has entered the era of the Internet,and a lot of online social software represented by WeChat has emerged on the Internet.As a product of the Web2.0 system,WeChat provides users with a lot of functions.WeChat social network has a wealth of information and users,which facilitates the breeding of WeChat rumors,and due to the semi-blocking nature of WeChat social network and strong privacy,the spread of rumors in WeChat social networks appears.With the new features,new types of rumors spread the types and paths.The thesis studies the characteristics,mechanism and WeChat user characteristics of WeChat rumors,in order to provide control strategies and suggestions for the official control of WeChat rumors.Firstly,the thesis introduces the research background and significance of the subject,and briefly reviews the domestic and international research status of the rumor,expounds the main research contents,research methods and chapter arrangement.Then elaborated the relevant theoretical concepts.Secondly,based on the previous research,the IP_o P_eSR rumor propagation model for WeChat social network is constructed.The effects of the first transmission rate,infection rate and other related parameters on rumor transmission are studied through simulation experiments and numerical analysis.Thirdly,based on the previous research,the T-IPSR rumor propagation model for WeChat social network is constructed.It also analyzes the influence of the user's altruistic motive,the user's own experience,the information superposition and the role of the rumor on the rumor spread.Finally,based on the numerical analysis of the model and the simulation results,a rumor control strategy based on WeChat social network is proposed. |
