A new research paper proposes a two-stage framework to address the opacity of Pseudo-Relevance Feedback (PRF) in information retrieval. The framework first involves a participatory audit with 108 users, which revealed that PRF only benefits about 20.9% of queries, while negatively impacting 25.6%. The second stage utilizes LLM-based rerankers to automatically predict user-derived labels, allowing for scalable inspection of PRF decisions. This approach aims to transform PRF from an opaque component into an auditable, user-grounded system. AI
IMPACT This research could lead to more transparent and effective information retrieval systems by improving how PRF is applied.
