Analysis Of The Public Opinion Spreading On Multi-community Network

In the real life, there is a large amount of complex system can be indicated andanalyzed by the network, and the research of complex network has made greatprogress in recent years. As the main study object in the paper, community structurearoused many researchers’ interest in diverse fields as a vital structure feature in thecomplex social network. With the development of information society,thedissemination of public opinion information is getting stronger and strongerdepending on the social network,and the network which constitutes multi-communitystructure plays an important role.Public opinion dissemination refers to the process ofpublic opinion information dissemination refers to the process of public opinioninformation spread based on the social network which has fast speed broad range buthard to control.In essence,public opinion dissemination is a group behaviorcommunicated among the subjects of public opinion which must be influenced by thecommunity where it is. Therefore, this paper not only deeply analyses thesubject,spread process and spread regulation of public opinion but also will discussthe influence of community feature and multi-community structure to the publicopinion spread regulation and community size. The inherent law of public opiniondissemination and the constitution parameter of the multi-community structure havereferential significance and practical value on analyzing the public opiniondissemination in the speech community.This paper summarizes what has been achieved on the study and utilizes thecomplex network and the epidemiological analysis method, combines the informationat present stage with the popular method SIR Model to analyze the phenomenon whenpublic opinion outbreaks in the process of public opinion spread which network contains many community structure and we adjust the parameter in order to controlthe public opinion spread in communities. Firstly, analyzed the process ofconstructing the multi-community network, the parameter of network constructer bythe constructed multi-community scale-free network model in which includes thesocialize intensity of multi-community network,by changing the parameter adjustedthe tightness degree of multi-community network in the community orcommunities,and balanced the social. Character in the network by themodularity,imitated in the multi-community scale-free network according to the SIRmodel; analyzed the spread in the community and community by changing theparameter of the spread model; observed the influence of public opinion spread incommunity by changing the average degree of spread model; we could find that therewas stronger social intensity if there was larger ratio of spread mode by changing thesocial intensity; observed the spread mode in the community by changing the node indifferent communities.In the above simulation analysis, we can get data which have important functionto analyze the public opinion spread in multi-community. Applied in the real socialnetworks, we can adjust the corresponding factors to change the large area outbreak inthe community structure network in order to control the spread of public opinioneffectively.
