摘要：While world knowledge has been shown to
improve learning-based coreference resolvers,
the improvements were typically obtained by
incorporating world knowledge into a fairly
weak baseline resolver. Hence, it is not clear
whether these benefits can carry over to a
stronger baseline. Moreover, since there has
been no attempt to apply different sources of
world knowledge in combination to coreference
resolution, it is not clear whether they offer
complementary benefits to a resolver. We
systematically compare commonly-used and
under-investigated sources of world knowledge
for coreference resolution by applying
them to two learning-based coreference models
and evaluating them on documents annotated
with two different annotation schemes.
