We report on experiments in reference res- olution using a decision tree approach. We started with a standard feature set used in previous work, which led to moderate re- sults. A closer examination of the perfor- mance of the features for different forms of anaphoric expressions showed good re- sults for pronouns, moderate results for proper names, and poor results for definite noun phrases. We then included a cheap, language and domain independent feature based on the minimum edit distance be- tween strings. This feature yielded a sig- nificant improvement for data sets consist- ing of definite noun phrases and proper names, respectively. When applied to the whole data set the feature produced a smaller but still significant improvement.
