Yong-Yeol Ahn

This week, my collaborator/friend from Barabasilab/award winning physicist, Yong-Yeol Ahn (better know as YY) is visiting the Center for Social Data here at DTU. If you’re anywhere near Copenhagen, I highly recommend you stop by to see his talk!

Title: Community structure and flocking of memes in social networks

Abstract: 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 co-operativity 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.

And if we’re lucky, maybe we can even talk him into speaking a bit about his interesting work on food pairings and molecular gastronomy!
