Introduces the 'Bag of Decisions' reranking concept, where an LLM dynamically generates query-specific Yes/No rubrics to assess relevance, replacing static judgment prompts. By decomposing search intent into concrete features (e.g., dimensions, usage, safety), this method enhances retrieval precision for complex semantics and offers a new prompt engineering paradigm for frontier rerankers like Jev.

Bag of Decisions Reranker: Using LLM-Generated Query-Specific Rubrics for Relevance Assessment
- Shifts from 'bag of terms' to 'bag of decisions', using LLMs to first understand query intent and generate fine-grained evaluation criteria before scoring.
- The generated rubrics consist of multi-dimensional Yes/No questions (e.g., child-sized dimensions, safety edges), making relevance assessment more interpretable and targeted.
- Demonstrates that combining LLM generation capabilities with specialized rerankers (like Jev) can overcome limitations of traditional vector retrieval in long-tail or complex-constraint queries.
