     Despite maintaining plausible general linguistic capabilities, dialogue models are still unable to fully discern facts and may instead hallucinate factually invalid information. […] Broadly speaking, we say that a neural dialogue system is guilty of hallucinating whenever it generates a factual sentence that is not supported by a valid path in a k-hop subgraph G k c ⊂ G of the original KG anchored around a context entity c. […] The first module flags and masks out hallucinated entities in an existing response and can be trained offline.
