Polarization in social media assists influencers to become more influential: analysis and two inoculation strategies

Ivan Garibay, Alexander V. Mantzaris, Amirarsalan Rajabi, Cameron E. Taylor
2019 Scientific Reports  
It is shown that prior to a polarization event a trend towards a more uniform distribution of relative influence is achieved which is then reversed by the polarization event.  ...  A methodological framework is proposed which represents key factors that drives social media engagement including the iterative accumulation of influence and the dynamics for the asymmetric treatment of  ...  The funders had no role in study design, data collection and analysis, decision to publish or preparation of the manuscript.  ...

How polarization can provide an increase in content dissemination amongst the highly ranked influencers [article]

Cameron E. Taylor, Ivan Garibay, Alexander V. Mantzaris
2018 arXiv   pre-print
This work extends a model of simulating influence in a network of stochastic edge dynamics to account for polarization.  ...  This model is extended to introduce the effects polarization. The fundamental assumption of the model is that a parameter of importance governs the rate of message responsiveness.  ...  To understand the underlying process in more detail we develop a model to capture the effects of the communication influence a network has before and after a polarization event to determine whether certain  ...

Cultural Polarization and the Role of Extremist Agents: A Simple Simulation Model [chapter]

Shade T. Shutters
2013 Lecture Notes in Computer Science  
Eliminating the extremist agent is only effective at the onset of cultural transition, while introducing a counter-extremist is effective at any time and will lead to a dynamic intermediate belief.  ...  Two possible methods of counteracting polarization are examined, removal of the extremist agent and introducing a counter-extremist which holds an immutable belief at the opposite extreme.  ...  Thus, effects of scale-free networks on the ability of extremist agents to polarize a society are examined in more detail.  ...

Influence And Dissemination Of Sentiments In Social Network Communication Patterns

Robert Hillmann, Matthias Trier
2013 European Conference on Information Systems  
Previous research suggests the existence of sentiments in online social networks.  ...  Our empirical results suggest a general influence of sentiments on node communication patterns that is evidenced by increased occurrences of subsequent messages that express the same sentiment polarization  ...  In case of the sentiment polarization change from positive to negative or vice versa (H1), the expected effect is also supported by the empirical results.  ...
