Construction and Analysis of the Opinion Formation Model Based on the Social Network
摘要
Abstract
By considering the interaction behaviors among the individuals, this papers present an evolutionary model of opinion formation, in which the individuals are embedded in a social network.The model supposes thats there are only two kinds of opinions for all of the individuals, including + 1 and - 1, and takes explicitly into account that an individual' s opinion is affected by its neighbors in the social network with a probability.The analytical and simulation results indicate that there exists a special probability λ.where the expected weighted fraction of the population that holds a given opinion is constant in time.While all of the population would be in the consensus state to other λc, value.This work may shed some light on evaluating the opinion spreading speed in a given social network.关键词
