This dataset contains Social and interaction graphs representing two large-scale Facebook regional networks. Social graphs describe Facebook friendships between users (anonymized), while interaction graphs contain links representing interactions between users (Facebook posts and comments on pictures) and are weighted by the number of interactions between the linked users. Interaction graphs cover four different temporal windows. The first three contain interactions occurred from respectively one month, six months and one year before the download to the time of the download. The last graph contains the whole history of communications of the users until the time of the download. The dataset was collected between March 2008 and May 2008.

The dataset has been first analyzed in Wilson, C., Boe, B., Sala, A., Puttaswamy, K. P., & Zhao, B. Y. (2009, April). User interactions in social networks and their implications. In Proceedings of the 4th ACM European conference on Computer systems (pp. 205-218). ACM.
