The article discusses a method for validating Retrieval-Augmented Generation (RAG) answers before presenting them to users, emphasizing the use of spans and quotes to verify evidence. It highlights that structured output is just the beginning of validation, and suggests incorporating a feedback loop to handle cases where evidence is not found. The approach aims to improve reliability in enterprise document intelligence applications.
