Kiefer, B., H-U. Krieger, J. Carroll and R. Malouf (1999) `A bag of useful techniques for efficient and robust parsing'. In Proceedings of the 37th Annual Meeting of the Association for Computational Linguistics, University of Maryland. 473-480.
This paper describes new and improved techniques which help a unification based parser to process input efficiently and robustly. In combination these methods result in a speed up in parsing time of more than an order of magnitude. The methods are correct in the sense that none of them rule out legal rule applications.
