In this paper, we introduce a novel evaluation framework based on sub-question coverage, which measures how well a RAG system addresses different facets of a question. We propose decomposing questions into sub-questions and classifying them into three types -- core, background, and follow-up -- to reflect their roles and importance. Using this categorization, we introduce a fine-grained evaluation protocol t","authors_text":"Caiming Xiong, Chien-Sheng Wu, Kaige Xie, Philippe Laban, Prafulla Kumar Choubey","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2024-10-20T22:59:34Z","title":"Do RAG Systems Cover What Matters?
