Hey all, TLDR: ORES extension [1] which is an extension that integrates ORES service [2] with Wikipedia to make fighting vandalism easier and more efficient is in the progress of deployment. You can test it in https://mw-revscoring.wmflabs.org (Enable it in your preferences first) You probably know ORES. It's an API service that gives probably of an edit being vandalism, it also does other AI-related stuff like guessing the quality of articles in Wikipedia. We have a nice blog post in Wikimedia Blog [3] and media paid some attention to it [4]. Thanks to Aaron Halfaker and others [5] for their work in building this service. There are several tools using ORES to highlight possibly vandalism edits. Huggle, gadgets like ScoredRevisions, etc. But an extension does this job much more efficiently. The extension which is being developed by Adam Wight, Kunal Mehta and me highlights unpatrolled edits in recentchanges, watchlists, related changes and in future, user contributions if ORES score of those edits pass a certain threshold. GUI design is made by May Galloway. ORES API ( ores.wmflabs.org) only gives you a score between 0 and 1. Zero means it's not vandalism at all and one means it's vandalism for sure. You can test its simple GUI in https://ores.wmflabs.org/ui/. It's possible to change the threshold in your preferences in the recent changes tab (you have options instead of numbers because we thought numbers are not very intuitive). Also, we enabled it in a test wiki so you test it: https://mw-revscoring.wmflabs.org. You need to make an account (use a dummy password) and then enable it in beta features tab. Note that building AI tool to detect vandalism in a test wiki sounds a little bit silly ;) so we set up a dummy model that probability of an edit being vandalism is backward of the last two digits (e.g. diff id:12345 = score:54%). In a more technical aspect, we store these scores in ores_classification table so we can do a lot more analysis with them once the extension is deployed. Fun use cases such as the average score of a certain page or contributions of a user or members of a category, etc. We passed security review and we have consensus to enable it in Persian Wikipedia. We are only blocked on ORES moving from Labs to production (T106867 [6]). The next wiki is Wikidata, we are good to go once the community finishes labeling edits so we can build the "damaging" model. We can enable it Portuguese and Turkish Wikipedia after March because s2 and s3 have database storage issues right now. For other Wikis, you need to check if ORES supports the Wiki and if community finished labeling edits for ORES (check out the table at [2]) If you want to report bugs or add feature requests you can find it in here [7].
