On the Dynamics of Network Public Opinion:A Research Based on Weisbuch-Deffuant Model
摘要
Abstract
Gaining an in-depth knowledge on the dynamics of network public opinions ( NPO) is becoming a more important element of current social management. Taking account of the forming field of NPO and the heterogeneity of agents, the study builds the dynamics rules of NPO by modifying Weisbuch-Deffuant model. Then the paper discusses the influence of the distribution ofμwhich is used to de-note one' acceptance of others' individual perspectives, the bounded confidenceε, and opinion leaders on the evolution process of NPO by a series of simulation experiments. The results show that, compared to the situation of μ following random distribution, NPO will con-venes at a much faster speed when μ is normally distributed with an average 0. 5; there is an inverse relationship between the value of bounded confidence ε and the final number of opinion clusters; and, the existence of opinion leaders will bring about the polarization of group's opinion, which is even true especially when the initial opinions held by opinion leaders are too biased.关键词
