Ordinary classification techniques can drive a conceptually simple constituent parser that achieves near state-of-the-art accuracy on standard test sets. Here we present such a parser, which avoids some of the limitations of other discriminative parsers. In particular, it does not place any restrictions upon which types of fea- tures are allowed. We also present sev- eral innovations for faster training of dis- criminative parsers: we show how train- ing can be parallelized, how examples can be generated prior to training with- out a working parser, and how indepen- dently trained sub-classifiers that have never done any parsing can be effectively combined into a working parser. Finally, we propose a new figure-of-merit for best- first parsing with confidence-rated infer- ences.
