Affinity Paths and information diffusion in social networks

José Luis Iribarren, Esteban Moro
2011 Social Networks  
Widespread interest in the diffusion of information through social networks has produced a large number of Social Dynamics models.  ...  We prove the plausibility of such mechanism through a stylized, agent-based model that replicates the Affinity Paths observed in real information diffusion cascades.  ...  Watts and Dodds (2007) built a model proving that information propagation can happen independently of the underlying social network structure and concluded that "large cascades of influence are driven  ...

The Dynamics of Protest Recruitment through an Online Network

Sandra González-Bailón, Javier Borge-Holthoefer, Alejandro Rivero, Yamir Moreno
2011 Scientific Reports  
We identify the network position of early participants (i.e. the leaders of the recruitment process) and of the users who acted as seeds of message cascades (i.e. the spreaders of information).  ...  We find that early participants cannot be characterized by a typical topological position but spreaders tend to me more central to the network.  ...  Acknowledgements We thank Mason A.
