Applications of group fairness to the assignment of reviewers in large conferences: https://arxiv.org/abs/2410.03474, via https://retractionwatch.com/2024/10/12/weekend-reads-a-lab-in-recovery-my-paper-was-proved-wrong-a-journal-apologizes/
The goal is to assign reviewers in such a way that no subcommunity feels it would be better off making its own splinter conference. Subcommunities are not part of the input; they are an emergent feature of the model. The model of reviewing is a little oversimplified: all papers are single-author, the only conflicts of interest are with one's own papers, there is a strict threshold of accepting scores that leads to acceptance, and only author preferences for reviewers rather than reviewer preferences for what to review are considered. And there is no consideration of the possibility that allowing authors power in selecting their preferred reviewers is a recipe for quid-quo-pro behavior and refereeing cartels. Still, I think it's an interesting idea.
