AI retrieval systems show bias against AAL and political leanings

By PulseAugur Editorial · [1 sources] ·

A new study published on arXiv reveals that dense retrieval systems exhibit bias based on identity signals present in user queries. Researchers found that these systems tend to retrieve documents aligning with the query's political lean and perform worse for queries written in African American Language (AAL) compared to White Mainstream English (WME). The study used controlled synthetic queries and naturalistic queries across political news and consumer-health domains, employing five dense retrievers and a sparse baseline. The findings suggest that these retrieval biases could exacerbate polarization and health disparities. AI

IMPACT Potential to exacerbate polarization and health disparities for marginalized language groups.

    Retrieval Sensitivity to Identity Signals in Queries

    Dense retrievers decide which documents reach users and the language models that use them, yet they are typically evaluated with neutral queries. We ask whether the identity signals that real users express in their queries---political ideology and dialect---bias what a retriever …
