[PDF] Top 20 WikiCREM: A Large Unsupervised Corpus for Coreference Resolution

... In this work, we address the lack of large train- ing sets for pronoun disambiguation by introduc- ing a large dataset that can be easily extended. To generate this dataset, we find passages of text where a ... See full document

... We adopted the MUC-6 guidelines for evaluating coref- erence relationships based on transitivity in anaphoric chains. For example, if {NP 1 , NP 2 , NP 3 } are all coref- erent, then each NP must be linked to one of the ... See full document
