Title: Community structure and flocking of memes in social networks
Spreading processes on networks (e.g. epidemic outbreak and information spreading) has been one of the most fundamental topics in network science. Information spreading in social networks has often been described by epidemic spreading models but recent studies demonstrated that some contagions (memes) exhibit fundamentally different pattern, where multiple exposure significantly enhances the transmission probability of the contagion. The cooperativity of a contagion makes the spreading process more sensitive to clustered network structure. Here we investigate the relationship between network communities and spreading of hashtags in a Twitter network.
