            The Winograd Schema Challenge (Levesque et al., 2011) is a reading comprehension task
            in which a system must read a sentence with a pronoun and select the referent of that pronoun from
            a list of choices. The examples are manually constructed to foil simple statistical methods: Each
            one is contingent on contextual information provided by a single word or phrase in the sentence.
            To convert the problem into sentence pair classification, we construct sentence pairs by replacing
            the ambiguous pronoun with each possible referent. The task is to predict if the sentence with the
            pronoun substituted is entailed by the original sentence. We use a small evaluation set consisting of
            new examples derived from fiction books that was shared privately by the authors of the original
            corpus. While the included training set is balanced between two classes, the test set is imbalanced
            between them (65% not entailment). Also, due to a data quirk, the development set is adversarial:
            hypotheses are sometimes shared between training and development examples, so if a model memorizes the
            training examples, they will predict the wrong label on corresponding development set
            example. As with QNLI, each example is evaluated separately, so there is not a systematic correspondence
            between a model's score on this task and its score on the unconverted original task. We
            call converted dataset WNLI (Winograd NLI)."""
