We show how a general grammar may be automatically adapted for fast parsing of utterances from a specific domain by means of constituent pruning and grammar specialization based on explanation-based learning. These methods together give an order of magnitude increase in speed, and the coverage loss entailed by grammar spe- cialization is reduced to approximately half that reported in previous work. Experi- ments described here suggest that the loss of coverage has been reduced to the point where it no longer causes significant perfor- mance degradation in the context of a real application.
