Welcome To OSN Group

In the last decade, the microblogging service Twitter has attained a massive world-wide following with some estimates putting the user base at more than 1 Billion users. Nonetheless, fundamental questions remain unanswered. We know, for instance, that discussions around certain topics “go viral” whereas other topics die an early death. The network propagates some ideas, and some make no headway. In view of the enormous influence of online social networks (OSN), understanding the mechanics of these systems is critical. To characterize the properties of popular and non-popular topics is of surpassing importance to our understanding of how these complex networks are shaping our world.

In this project, we aim to study the spatio-temporal and events based characteristics of topics spread and its applications in content distribution networks. We also aim to study how the behavior of the small minority of very popular users on Twitter differs from that of the bulk of the population of ordinary users, and how these differences may impact information diffusion.
