Coreference resolution is a very knowledge-intensive task, so it is natural to try to apply semi-supervised or unsupervised methods:
David Bean and Ellen Riloff.
Unsupervised learning of contextual role knowledge for coreference resolution.
Proc. HLT/NAACL 2004.
Learns pairs of predicates which are likely to govern references to the same entity, starting with reliable coreference pairs. Applied in two narrow domains, terrorism and disasters.
Xiaofeng Yang and Jian Su.
Coreference resolution using semantic relatedness information from
automatically discovered patterns.
Proc. ACL 2007.
Acquires information on semantically-related pairs, particularly proper name-noun pairs.
