This paper provides an overview of the NIST TREC 2020 Fair Ranking track. For
2020, we again adopted an academic search task, where we have a corpus of
academic article abstracts and queries submitted to a production academic
search engine. The central goal of the Fair Ranking track is to provide fair
exposure to different groups of authors (a group fairness framing). We
recognize that there may be multiple group definitions (e.g. based on
demographics, stature, topic) and hoped for the systems to be robust to these.
We expected participants to develop systems that optimize for fairness and
relevance for arbitrary group definitions, and did not reveal the exact group
definitions until after the evaluation runs were submitted.The track contains
two tasks,reranking and retrieval, with a shared evaluation.
