Welcome to the home of Wikimedia Research.


We are a team of data scientists, UX researchers, and engineers at the Wikimedia Foundation using data to understand and empower millions of readers and contributors who interact with Wikipedia and its sister projects on a daily basis. We turn research questions into publicly shared knowledge, we design and test new technology, we produce empirical insights to support product and engineering decisions and we publish research informing the organization’s and the movement’s strategy. We are strongly committed to principles of transparency, privacy and collaboration; we use free and open source technology and we collaborate with researchers in the industry and academia.


Increasing content coverage

Revision scoring as a service

WMF Metrics & Activities Meeting September 2015.pdf The Revision Scoring Service (Wikimania 2015).pdf

We're designing and testing recommender systems to accelerate the rate of content creation and help our contributors and content translators fill the gap between content supply and demand in Wikipedia across languages. Watch a presentation of our results or read more about this project.

We're building machine learning classifiers to make automated quality assessment available as a service to content curators and tool developers. We designed APIs to compute article and edit quality scores and an extensible framework for rolling out new models trained with user input. Learn more about this project and the code behind it.

  • Our research reports mostly live in the Research namespace on Meta
  • We host every month a showcase where we present publicly our work. We occasionally invite guest speakers involved in Wikimedia research. You can browse past editions of the showcase on this page. The showcase has been running monthly since December 2013.
  • If you're interested in staying on top of both internal and external research on our projects, check out our monthly newsletter (which you can also subscribe to by mail) or follow @WikiResearch on Twitter. The newsletter is mostly volunteer effort coordinated by Tilman and Dario and has been proudly running since April 2011.
  • You can reach us on IRC via the irc:wikimedia-research channel or drop us a line at (
