The goal is the development of a practical vandalism detector that is capable of telling apart ill-intentioned edits from well-intentioned edits. Such a tool, which will work somewhat like a spam detector, will release the crowd's workforce currently occupied with manual and semi-automatic edit filtering. The performance of submitted detectors will be evaluated based on a large collection of human-annotated edits, which has been crowdsourced using Amazon's Mechanical Turk. Everyone is welcome to participate."
