Opinion formation in social networks

Akylai Taalaibekova ()

Operations Research and Decisions, 2018, vol. 2, 85-108

Abstract: In this paper we discuss a number of selected works on the dynamics of opinions and beliefs in social networks. We consider both Bayesian and non-Bayesian approaches to social learning, but focus our analysis on a simple, tractable and widely used model of updating beliefs – the DeGroot model. We study the dynamics of opinions based on the DeGroot model from different points of view. First, its attractive features and shortcomings are discussed and then some of its extensions are presented. These models are based on the DeGroot updating rule, but additionally incorporate the possibility of improvements and enrichments of the framework.
