Title: Features for Discriminative Parsing

Abstract:
Statistical approaches to natural language parsing have become the method of 
choice because they provide a systematic way of combining features or soft 
constraints in a unified model.  Moreover, the weight or importance of each 
feature can be automatically learnt from training data.  After reviewing 
the "generative" and "discriminative" approaches to statistical parsing I 
describe a discriminative parsing system using regularized Maximum Entropy 
estimation, and discuss the linguistic details of the features that turn out to 
be most useful for statistical parsing.
