Towards Measuring Fairness in Grid Layout in Recommender Systems

no code implementations19 Sep 2023 Amifa Raj, Michael D. Ekstrand

We examine how fairness scores change with different ranking layouts to yield insights into (1) the consistency of fair ranking measurements across layouts; (2) whether rankings optimized for fairness in a linear ranking remain fair when the results are displayed in a grid; and (3) the impact of column reduction approaches to support different device geometries on fairness measurement.

Patterns of gender-specializing query reformulation

no code implementations25 Apr 2023 Amifa Raj, Bhaskar Mitra, Nick Craswell, Michael D. Ekstrand

There are many ways a query, the search results, and a demographic attribute such as gender may relate, leading us to hypothesize different causes for these reformulation patterns, such as under-representation on the original result page or based on the linguistic theory of markedness.

Overview of the TREC 2021 Fair Ranking Track

no code implementations21 Feb 2023 Michael D. Ekstrand, Graham McDonald, Amifa Raj, Isaac Johnson

The 2021 Fair Ranking track aimed to ensure that documents that are about, or somehow represent, certain protected characteristics receive a fair exposure to the Wikipedia editors, so that the documents have an fair opportunity of being improved and, therefore, be well-represented in Wikipedia.

Much Ado About Gender: Current Practices and Future Recommendations for Appropriate Gender-Aware Information Access

no code implementations12 Jan 2023 Christine Pinney, Amifa Raj, Alex Hanna, Michael D. Ekstrand

Information access research (and development) sometimes makes use of gender, whether to report on the demographics of participants in a user study, as inputs to personalized results or recommendations, or to make systems gender-fair, amongst other purposes.

Pink for Princesses, Blue for Superheroes: The Need to Examine Gender Stereotypes in Kid's Products in Search and Recommendations

no code implementations13 May 2021 Amifa Raj, Ashlee Milton, Michael D. Ekstrand

In this position paper, we argue for the need to investigate if and how gender stereotypes manifest in search and recommender systems. As a starting point, we particularly focus on how these systems may propagate and reinforce gender stereotypes through their results in learning environments, a context where teachers and children in their formative stage regularly interact with these systems.
