The dataset is composed of 595,460 users, 14,273,311 links, 1,345,913 diffusion cascades, and 1,311,498 tags from Mar 24 to Apr 25, 2012. In order to capture more information cascades, Weng et al. set the tracking objects as a group of users who are connected with mutual following. Thus, the follower network is an undirected network made up of a number of disconnected components.
