Abstract

In this work, we introduce a novel metric for auditing group fairness in ranked lists. Our approach offers two benefits compared to the state of the art. First, we offer a blueprint for modeling of user attention. Rather than assuming a logarithmic loss in importance as a function of the rank, we can account for varying user behaviors through parametrization. For example, we expect a user to see more items during a viewing of a social media feed than when they inspect the results list of a single web search query. Second, we allow non-binary protected attributes to enable investigating inherently continuous attributes (e.g., political alignment on the liberal to conservative spectrum) as well as to facilitate measurements across aggregated sets of search results, rather than separately for each result list. By combining these two elements into our metric, we are able to better address the human factors inherent in this problem. We measure the whole sociotechnical system, consisting of a ranking algorithm and individuals using it, instead of exclusively focusing on the ranking algorithm. Finally, we use our metric to perform three simulated fairness audits. We show that determining fairness of a ranked output necessitates knowledge (or a model) of the end-users of the particular service. Depending on their attention distribution function, a fixed ranking of results can appear biased both in favor and against a protected group1.

  • Facebook provides a relevance score between 1 and 10, calculated based on expected positive and negative feedback from the target audience.

    “Facebook provides advertisers with an overview of how well-matched it believes an ad is with the target audience using a metric called relevance score, which ranges between 1 and 10.Facebook says [68]: Relevance score is calculated based on the positive and negative feedback we expect an ad to receive from its target audience.”

  • Facebook's ad delivery system is designed to show the right content to the right people, and a high relevance score is seen by the system as a positive signal.

    “Facebook goes on to say [68]: Put simply, the higher an ad's relevance score, the less it will cost to be delivered.This is because our ad delivery system is designed to show the right content to the right people, and a high relevance score is seen by the system as a positive signal.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
