社交网络中考虑动态群体压力的舆情演化模型
Opinion Dynamics Model with Varying Group Pressure in Social Networks
摘要
Abstract
Aiming at the problem that the expressed and private opinion dynamics model(EPO)cannot capture the dynamic changes in group pressure and cannot explain the classic social psychology theory of"spiral of silence"(SOS),an improved EPO model is proposed.Firstly,the community structure theory is introduced into the model to characterize the local homo-geneity and global differences of public opinion distribution.Secondly,a dynamic weighting algorithm is proposed to inte-grate and model the key mechanisms of SOS theory,including opinion climate,quasi-sensory statistics,and fear of isola-tion index.On this basis,the convergence and stability of the model are demonstrated through theoretical analysis.Finally,the model is simulated on a real network and compared with the original EPO model.The simulation results show that compared with the original model,the improved model can accurately simulate the attenuation process of minority opinions and the self strengthening effect of majority opinions in real social networks.It can more accurately capture the evolution rules of opinions under group pressure in social networks,which are significantly in line with the core conclusion of SOS theory.关键词
