TREC 2021 Fair Ranking Track

The TREC Fair Ranking track evaluates systems according to how well they fairly rank documents. The 2021 track focuses on fairly prioritising Wikimedia articles for editing to provide a fair exposure to articles from different groups.

Tentative Timeline

The files are also available from a Globus repository. Most US research universities, and many other institutions, support Globus; you can also download the files with Globus Connect Personal. You can also access the file repository by HTTP through the Boise State data repository.
