Wikipedia and Wikimedia projects are among the most visited repositories of human knowledge. They are also a unique source of data for understanding how we collaborate to create that knowledge, access it and share it with others.

The Wikimedia Foundation’s Research and Data Team has recently published a number of open data sets about Wikimedia projects, making them freely available to everyone – researchers, developers and community members – under a CC0 license. These aggregate data sets were collected to show general trends about how people use Wikimedia projects and do not include any personal information about users, as required by Wikimedia’s privacy policy.

We invite you to turn this data into useful insights, applications and visualizations, and help our communities and projects thrive. If you have any questions on these releases, feel free to reach out to the Research and Data team via the Analytics mailing list or our #wikimedia-research channel on IRC.

Wikipedia clickstream

This data set shows how people get to a Wikipedia article and what links they click on next. The most recent release captures 22 million pairs (referer, resource), extracted from a total of 3.2 billion requests to the English Wikipedia. We wrote a step-by-step tutorial and IPython notebook to get you started with this data.
