The NLI model is then run on each (u i , p j ) pair, predicting a label y i,j ∈ {E, N, C} with confidence c i,j .
a contradiction score is computed for each candidate as: if the candidate u i does not contradict any persona sentence p j according to the NLI  is the highest confidence, c i,j , out of the contradicting (u i , p j ).
