RefChecker: Reference-based fine-grained hallucination checker and benchmark for large language models
By Xiangkun Hu, Dongyu Ru, Tianhang Zhang, Zheng Zhang| Amazon Science@ Large Language Models (LLMs) have shown impressive capabilities but also a concerning tendency to hallucinate. This paper presents REFCHECKER, a framework that introduces claim-triplets to represent claims in LLM responses, aiming to detect fine-grained hallucinations.
