  A Winograd schema is a pair of sentences that differ in a single word and
that contain an ambiguous pronoun whose referent is different in the two
sentences and requires the use of commonsense knowledge or world knowledge to
disambiguate. This paper discusses how Winograd schemas and other sentence
pairs could be used as challenges for machine translation using distinctions
between pronouns, such as gender, that appear in the target language but not in
the source.
