A version of the PersonaChat dataset that has been true-cased, and also has been given more normalized punctuation.
The original PersonaChat dataset is in all lower case, and has extra space around each clause/sentence separating
punctuation mark. This version of the dataset has more of a natural language look, with sentence capitalization,
proper noun capitalization, and normalized whitespace. Also, each dialogue turn includes a pool of distractor
candidate responses, which can be used by a multiple choice regularization loss during training.
