We present a noun phrase coreference sys- tem that extends the work of Soon et al. (2001) and, to our knowledge, pro- duces the best results to date on the MUC- 6 and MUC-7 coreference resolution data sets — F-measures of 70.4 and 63.4, re- spectively. Improvements arise from two sources: extra-linguistic changes to the learning framework and a large-scale ex- pansion of the feature set to include more sophisticated linguistic knowledge.
