1. On the Origin of Hallucinations in Conversational Models: Is it the Datasets or the Models? (2022 · 205 citations)
   Knowledge-grounded dialogue systems often produce statements that their supplied knowledge does not support.
2. Neural Path Hunter: Reducing Hallucination in Dialogue Systems via Path Grounding (2021 · 149 citations)
   Large pre-trained dialogue models produce fluent replies, but they often state facts that are wrong. This paper tackles that problem for dialogue grounded in a Knowledge Graph (KG). The authors first ran a crowd-sourced human study of GPT-2 responses fine-tuned on OpenDialKG. It showed that most errors are extrinsic…
3. FaithDial: A Faithful Benchmark for Information-Seeking Dialogue (2022 · 138 citations)
   Knowledge-grounded dialogue systems often hallucinate: they make claims their knowledge source does not support.
