Empirical Analysis of User Participation in Online Communities: the Case of Wikipedia


We study the distribution of the activity period of users in five of the largest localized versions of the free, online encyclopedia Wikipedia. We find it to be consistent with a mixture of two truncated log-normal distributions. Using this model, the temporal evolution of these systems can be analyzed, showing that the statistical description is consistent over time.
