Bootless Application of Greedy Re-ranking Algorithms in Fair Neural Team Formation
Published in ECIR-BIAS, 2023
Team formation aims to automate forming teams of experts who can successfully solve difficult tasks, which have firsthand effects on creating organizational performance. While existing neural team formation methods are able to efficiently analyze massive collections of experts to form effective collaborative teams, they largely ignore the fairness in recommended teams of experts. Fairness breeds innovation and increases teams’ success by enabling a stronger sense of community, reducing conflict, and stimulating more creative thinking. In this paper, we study the application of state of-the-art deterministic greedy re-ranking algorithms to mitigate the potential popularity bias in the neural team formation models based on demographic parity. Our experiments show that, first, neural team formation models are biased toward popular experts. Second, although deterministic re-ranking algorithms mitigate popularity bias substantially, they severely hurt the efficacy of teams. The code to reproduce the experiments reported in this paper is available at Adila’s Repository
