Venue: CS101.Abstract:
More and more social interactions are migrating online. In this talk we study patterns of such interactions in social applications including email, newsgroups, instant messaging, and microblogging. In particular, we examine the structural properties of conversational trees that arise from such interactions. We argue that existing graph models cannot generate these trees and propose a simple model for conversational trees. If time permits, we will also address the general data mining, modeling, algorithmic challenges that arise as part of studying online social networks.
