The #anti-harassment Tools team is going to be working on a tool to assist users in finding sockpuppets on Wikimedia projects. It is still quite early in the planning phase.
The planned feature ideas are something like below:
# User enters two usernames/IPs and the model returns a similarity score for the users with information about which features were a high match
# User enters a single username/IP and the model returns other users with a high similarity score and information about which features were a high match
# User enters a sequence of usernames/IPs and the model returns groups of which users seem to be similar and information about which features were a high match
This feature-set will likely be built into a new special page in mediawiki or be mae a part of the checkuser extension.
The work for building the machine learning model is being done in {T236299}. Once that work is complete, we will need an API for accessing this data via a MediaWiki interface. The API will need to be restricted to a specific user group (likely checkusers).
We would like to have the API available by November 2020.
