  1. Entity Labels Are Not Entity Signals: A Framework for Observable Relevance in Document Re-Ranking

    A new research paper proposes a framework to improve document re-ranking by distinguishing between conceptual entity relevance and observable entity relevance. The authors argue that current entity-aware retrieval methods incorrectly assume that topically relevant entities are always useful for ranking. They introduce Observable Entity Relevance (OER) as a measure of whether an entity's observed presence in a collection effectively discriminates relevant from non-relevant documents. Experiments show that aligning supervision with OER significantly improves document pruning and retrieval performance compared to traditional methods like BM25. AI
