Majority Rule for Belief Evolution in Social Networks [article]

Yi Zhou
2013 arXiv   pre-print
In this paper, we study how an agent's belief is affected by her neighbors in a social network.  ...  The answer is no in general. However, for random asynchronous belief evolution, this is indeed the case.  ...  Related Work Belief and opinion dynamics in social network is widely studied in related fields.  ...

On the Impact of Social Media Recommendations on Opinion Consensus [article]

Vincenzo Auletta, Antonio Coppola, Diodato Ferraioli
2022 arXiv   pre-print
In particular, we show that when the homophily ratio is large, the social media has a very low capacity of determining the outcome of the opinion dynamics.  ...  We consider a discrete opinion formation problem in a setting where agents are influenced by both information diffused by their social relations and from recommendations received directly from the social  ...  In the section 5 we will study the opinion dynamics with asynchronous updates.  ...

2014 Proceedings of the 23rd ACM International Conference on Conference on Information and Knowledge Management - CIKM '14  
Further, actors' opinions may be observed in an asynchronous and incomplete fashion, after missing several time steps when an actor changed its opinion based on neighbors' influence.  ...  These opinions are influenced by network neighbors. Many models have been proposed for such opinion dynamics, but they have some limitations. Most consider the strength of edge influence as fixed.  ...  MODEL AND METRICS In this section, we describe a new framework for modeling opinion dynamics on a social network.  ...
