Project Summary edit
This competition challenges data-mining experts to build a predictive model that predicts the number of edits an editor will make in the five months after the end date of the training dataset. The dataset is randomly sampled from the English Wikipedia dataset from the period January 2001 - August 2010.
The objective of this competition is to quantitively understand what factors determine editing behavior. We hope to be able to answer questions, using these predictive models, why people stop editing or increase their pace of editing.
Contestants are expected to build a predictive model that can be reused by the Wikimedia Foundation to forecast long term trends in the number of edits that we can expect.
Methods edit
Participants are free to use any econometric / statistical method or machine learning approach.
