We propose an adaptive ensemble method to adapt coreference resolution across domains. This method has three features: (1) it can op- timize for any user-specified objective mea- sure; (2) it can make document-specific pre- diction rather than rely on a fixed base model or a fixed set of base models; (3) it can auto- matically adjust the active ensemble members during prediction. With simplification, this method can be used in the traditional within- domain case, while still retaining the above features. To the best of our knowledge, this work is the first to both (i) develop a domain adaptation algorithm for the coreference reso- lution problem and (ii) have the above features as an ensemble method. Empirically, we show the benefits of (i) on the six domains of the ACE 2005 data set in do...
