Chain-of-Note improves RAG by adding a relevance-checking step

A new method called Chain-of-Note aims to improve the reliability of retrieval-augmented generation (RAG) systems by adding a crucial intermediate step. Instead of directly answering questions from retrieved passages, Chain-of-Note first requires the system to generate a relevance note for each passage, assessing its actual content and support for the query. The system then answers the question using only passages deemed relevant, and explicitly states "I don't know" if no relevant passages are found. This approach helps mitigate issues like answering questions outside the corpus or being misled by passages with keyword overlap but no factual connection. AI

IMPACT Enhances the reliability of RAG systems, reducing hallucinations and improving accuracy in question-answering tasks.
