Research On Social Network Structure Andevolution Of Network Collective Behavior

In recent years,the Internet technology and network intelligent terminal has made rapid development.Microblogging,blog,BBS,WIKI,and a variety of social networking sites have been born,the form of information service innovation for the release of public opinion discourse possible.The emergence of cluster behavior provides favorable conditions and makes the social network behind network cluster behavior more complex.Based on the above reasons,this paper chooses the recent typical cluster behavior of the network,and using the social network analysis method,static analysis and dynamic evolution analysis to analyze the cluster network structure deeply and systematically so as to deal with the network cluster behavior for the crisis management organization providing evidence.First of all,this paper defines the concept of network cluster behavior and group event,and analyzes the association between network cluster behavior and real group event.Then,from the perspective of the event type of network cluster behavior,the typical cluster events happened in the past five years are summarized and the characteristics of network cluster behavior are summarized,and the key factors of network cluster behavior are put forward.Secondly,the theory of social network analysis is expounded.On this basis,the data of "Luoer fraud" event obtained from the microblogging platform are modeled,and the social network analysis method is used to analyze the individual structure and network.The clustering coefficient and the degree index are used to analyze the network model,and the characteristics of the social network structure hidden behind the network cluster behavior are excavated,and the characteristics of the network are analyzed.The overall structure of the key nodes.Finally,according to the data of the five stages of the "Luoer fraud" incident,the social network structure model is constructed,and the dynamic evolution process is analyzed from the three basic attributes of degree index,average path length and agglomeration coefficient.And the complexity of the network model is proposed,and the effectiveness of the improved power rate scale-free network model is verified by computer simulation program.Based on the analysis of the static and dynamic evolution of the social network structure of network cluster behavior,this paper puts forward the prevention,disposal and intervention measures of network cluster behavior...
