we  would like to announce a research project with the goal of studying whether user interactions recorded at the time of editing are suitable to predict vandalism in real time.
Should vandal editing behavior be sufficiently different from normal editing behavior, this would allow for a number of interesting real-time prevention techniques. For example:
- withholding confidently suspicious edits for review before publishing them,
- a popup asking "I am not a vandal" (as in Google's "I am not a robot") to analyze vandal reactions,
- a popup with a chat box to personally engage vandals, e.g., to help them find other ways of stress relief or to understand them better,
- or at the very least: a new signal to improve traditional vandalism detectors.
We have set up a laboratory environment to study editor behavior in a realistic setting using a private mirror of Wikipedia. No editing whatsoever is conducted on the real Wikipedia as part of our experiments, and all test subjects of our user studies are made aware of the experimental nature of their editing. We plan on making use of crowdsourcing as a means to attain scale and diversity.
If you wish to participate in this study as a test subject yourself, please get in touch. The more diversity, the more insightful the results will be. We are also happy to collaborate and to answer all questions that may arise in relation to the project. For example, our setup and tooling may turn out to be useful to study other user behavior-related things without having to actually deploy experiments within the live MediaWiki.
PS: The AICaptcha project seems most closely related. @Vinitha and Gergő: If you wish, we can set up a Skype meeting to talk about a avenues for collaboration.
