A Study On The Transmission And Evolution Of Heterogeneous Individual Opinion From The Perspective Of Complex Network

In recent years,the reasons for the formation of individual opinions and factors influencing their changes have been widely concerned by academics,and afterwards they have acquired fruitful research results.Especially along with the unfolding of internet technology and the birth of social media in recent years,individuals are not isolated any more,but as a portion of social groups to participate in the process of socialization where they interact with each other and present their influence to other individuals.However that is the mutual influence promoting the progress of information technology and further society.Thus it is very important to research the internal mechanism of the formation and transformation of individual opinion and explore the evolution of group opinion,which plays a significant role in leading the direction of social group advancement.In this article,the theory carding and simulation modeling processes are segmented into two aspects,composed by individual and social network.From the angle of individual,we focus on the analysis of individual heterogeneity,opinion transmission and transformation,while respecting social network,the structure,dynamic and opinion evolution are followed.In the first place,we draw on the correlation theory of individual heterogeneity and similarity,then referring to these basic theories we establish a measurement model to quantify individual's characteristics which are composed of similarity,local influence and global influence,hereafter probe into heterogeneity.With respect to opinion,in order to figure out the formation and transformation mechanism of individual opinion,we explore five opinion transformation models incorporating Persuasion theory,Opinion dynamics model,Limited trust model,SIR model,Influence network model.As a result,we obtain two types of opinion which are discrete form derived from Influence network model and continuous mold base on Limited trust model.Afterwards,in regard to transmitters,we divided them into the connected neighbors and the mass media two aspects.Secondly,for the social network,we summarize the structural characteristics of complex network,and the models about network evolution.On that basis,we work out two design of how the social network evolves in compose of edge reconnection and new nodes adding in over time,besides we extract the common parameters of the opinion evolvement model,to assist the follow-up development of experimental tool,and the configuration of parameters to generate what we need in the simulation experiments,moreover provide convenience for the later simulation experiment.Based on the model established above,we go deep into individual and network aspects to investigate how these points deliver an impact on the opinion transmission and evolvement processes and what are results of group opinion evolvement over the interacting among individuals happening according to the opinion formation and transformation mechanisms,in use of the developed experimental tools to acquire different parameters configuration.
