Empirical Analysis of User Participation in Online Communities: the Case of Wikipedia - scientific work related to Wikipedia quality published in 2010, written by Giovanni Luca Ciampaglia.

Overview

Authors study the distribution of the activity period of users in five of the largest localized versions of the free, on- line encyclopedia Wikipedia. Authors find it to be consis- tent with a mixture of two truncated log-normal distri- butions. Using this model, the temporal evolution of these systems can be analyzed, showing that the statis- tical description is consistent over time. contributions: 1. Authors find all datasets to be consistent with the hypothesis that the lifetime of an user account is described by the su- perposition of two truncated log-normal distributions. An interpretation for this phenomenon is that two different regimes govern the participation of individuals to these versions of the Wikipedia project: the occasional users, who fail to find interest in the project after the first few at- tempts to contribute, and the long-term users, whose with- drawal is probably more related to external factors like the loss of personal incentives in contributing and similar causes. 2. Using model, authors characterize how the participation of users over time evolves, as the system ages. Authors find that the statistical description of the one-timers is stable over time, while the properties of the group of long-term users change as a consequence of the aging of the system. 3. Authors find evidence that the inter-edit time distribution de- cays with an heavy tail. In view of this finding, authors check that analysis is not affected by the choice of the pa- rameter used for determining when an user is to be con- sidered "inactive"; authors find that for the one-timers it has no quantitative effect. For the statistics of the long-lived users authors find instead a very good qualitative agreement.
