Modelling Facebook users' activity to information diffusion in the social network.

Summary This paper aims to better understand information diffusion in social networks. When a Facebook user updatea content on his wall, his Facebook friends can comment it, click on "like" or share it on their wall, allowing to measure user contribution to content diffusion. Using a database collected with a specific Facebook application, we model Facebook users' activity (posts, likes, comments, activity on friends'wall) by friendship network structure, profile and friends' activities.
