In this paper, we focus on English Wikipedia, one of the main user-contributed content systems, and study the problem of predicting which users will become inactive and stop contributing to the encyclopedia. We propose a predictive model leveraging frequent patterns appearing in user's editing behavior as features to predict active vs. inactive Wikipedia users. Our experiments show that our method can effectively predict inactive users with an AUROC of 0.97 and significantly beats competitors in the task of early prediction of inactive users.
