The noun-pair-based features for the CR model can be generated using essentially the same method.
since each instance now corresponds to an NP, NP k , and a preceding cluster, c, we can generate a noun-pair-based feature by applying the above method to NP k and each of the NPs in c, and its value is the number of times it is applicable to NP k and c. As discussed above, features encoding the semantic roles of two NPs and the relatedness of the associated verbs could be useful for coreference resolution.
