Research On Dissemination Characteristics And Intervention Strategies Of Three-tier Coupled Network

With the development of communication technology and the popularity of mobile terminals,the cross platform communication between users on social platforms and big V media promotes the rapid diffusion of information on multimedia fusion networks.In particular,in the face spread of emergencies on the multimedia fusion network,analyzing the network topology of information carrier and its propagation mechanism has very important theoretical value and practical significance for efficient propagation and rapid suppression.Therefore,around the problems of information characteristics,dissemination environment and suppression or dissemination conditions,how to establish information cross platform dissemination model,to evaluate dissemination characteristics and to put forward suppression or diffusion strategies are particularly important.In view of the above problems,this paper constructs a theoretical framework of a three-tier coupled network communication model TCNM from the perspective of the generation of information communication characteristic model,communication conditions and the influence of communicators,and focuses on the influence of communicators on communication characteristics such as communication cycle and outbreak threshold at different levels,as well as the corresponding intervention strategies.The main research contents are as follows:(1)A theoretical system of information dissemination model be constructed.Firstly,a three-layer carrier function network is constructed through the transmission ways and methods of information in cross platform and the characteristics of entity objects in single platform;Secondly,according to the node coupling relationship between layers,nine kinds of network models are divided into three categories,and the model parameters and the coupling relationship between layers are analyzed,which provides model guarantee for the follow-up research;Finally,the informationpropagation state in network TCNM is determined based on SIR propagation mechanism.(2)The method of node propagation influence on TCNM is studied.Firstly,aiming at the problem of how to find super communicators,combined with the global and local characteristics of the network,seven propagation source indexes based on neighbors,paths and eigenvalues are determined;Secondly,the simultaneous interpreting of the influence of different sources of communication indicators on the propagation characteristics is carried out in different network models.Finally,several evaluation indexes suitable for representing communicators in TCNM network model are determined.(3)The problem of information dissemination control on TCNM is studied.Firstly,the problem of information intervention strategy is proposed from the structure of three-tier coupled network communication model;Secondly,considering the node importance and network connectivity respectively,two information intervention strategies are proposed,namely,the node importance measurement intervention strategy based on the fusion of node neighbors and node accessibility and the intervention strategy based on huge connected branches;Finally,the two intervention strategies and classical intervention strategies are used to compare and analyze in the global network and local media layer network respectively on a specific three-layer coupling network model.(4)Design and implementation of visualization platform for information dissemination situation analysis.The three-tier information dissemination platform is designed and displayed for the purpose of intuitive information dissemination.
