Reducing Dialogue Consistency to NLI Identifying utterances which contradict previous utterances or an agent's persona can be reduced to natural language inference by assuming that contradictions are contained in a sentence pair.
given a persona P A = {p A 1 , ..., p A m } for agent A and a length- T , it is assumed that a dialogue contradiction for agent A is contained in an utterance pair (u A i , u A j ), and a persona contradiction is contained in a pair (u A i , p A k ).
