Indeed, awesome to see another method leverage rerankers with document proximity to overcome first-stage recall limitations 🤓
Mandeep Rathee@rathee_mandeep

Happy to see another research group, @haike_xu working in the same direction and our SlideGAR in the BRIGHT world. However, Reranker-Guided Search is not new. There are papers like Quam (WSDM'25), ORE (SIGIR'25), ReFIT(SIGIR'25), TOUR (ACL'23) that use the ranker's guidance.

🚨 New Pre-Print! You've just added your 600th model to your negative mining pool and filtered all false negatives. Does any of this even matter when we can apply distillation? In this work with @debforit and @macavaney, we explore data selection in modern ranking. 🧵 Below

Disentangling Locality and Entropy in Ranking Distillation @MrParryParry et al. separate example selection effects from teacher ranking entropy in neural ranking model optimization, showing complex hard-negative pipelines offer minimal gains. 📝arxiv.org/abs/2505.21058

@macavaney @din0s_ Hi @macavaney thanks for the comment. We did not directly compare the knowledge distillation directly yet. I'll share soon once I have numbers. We internally had the same suggestion, however, we didn't think KD was central to the paper in our comparison until the deadline.

@beirmug @din0s_ Nice work! As you point out in the paper, the approach is related to existing distillation methods. I see some analysis of this in Section 6, but I would love to see a direct head-to-head comparison. Have you tried this? Might make good appendix material.

As @hscells et al say: ♻️ Reduce, Reuse, Recycle! It's never been easier to share indexes (Terrier, Anserini, Pisa, Dense, etc.) using HuggingFace, Zenodo, etc. 🤓
