Research On Multi Layer Network Pseudo Information Diffusion And Intervention Based On Community Structure

Pseudo information is different from ordinary false information,and usually has a strict false information kernel and the reality of some representation,so it is more confusing.Because the false information in the public crisis is mostly related to people's basic interests,it is more likely to cause the blind communication of the group.In recent years,with the rapid development of network technology,the influence of the network media forms have become increasingly prominent,has become a powerful force of the communication tool,a profound impact on the field of social science,politics and economy etc..Among them,the spread of false information,such as WeChat,micro-blog and forums,is easy to evolve into a public crisis.It is the focus of social harmony and stability in recent years.Once the public crisis is triggered,it will cause incalculable property damage.To prevent the emergence of public crisis,we must intervene before the spread of false information reaches a certain scale(threshold).Based on the above background,firstly,according to the actual diffusion path of false information,the analysis of topological structure of online social networks and offline social networks,so as to construct the network topology in the double fake information diffusion in public crisis.The mechanism of information diffusion under free diffusion is studied,and the impact of different kinds of nodes as the initial outbreak nodes on the final burst size and time of pseudo information is obtained.Secondly,the concept of community structure is introduced to identify the order of node influence in the double-layer network based on community structure,which lays the foundation for the next intervention strategy for pseudo information.In the node influence recognition process,based on the classical K-shell node method,a new identification method named Nc value of the computing node is proposed,and the accuracy of the recognition result is verified by the SIR model.Finally,under the premise of defining the mechanism of information diffusion,the microscopic characteristics of nodes and edges in double layered networks and thedynamical mechanism in the process of pseudo information diffusion are set up.According to the attributes of the nodes,the intervention strategy in the process of pseudo information diffusion is set up.The SIR model was applied to netlogo software to verify the accuracy of different intervention strategies.
