This is an anti-vandalism bot census for all Wikimedia projects as of February 2011. It includes active and inactive bots, also simple clones of other bots. The main goal of this census is compiling all the information available about these counter-vandalism automatic tools. Feel free to help improve this page.
Techniques
editWe can see two main types of anti-vandalism bots:
- First generation: simple scoring systems based in regular expressions and heuristics.
- Second generation: machine learning, natural language processing, neural networks and bayesian filters.
