speeding up full syntactic parsing

... 295–300, Sydney, July 2006. c 2006 Association for Computational Linguistics Speeding Up Full Syntactic Parsing by Leveraging Partial Parsing Decisions Elliot Glaysher and Dan Moldovan Language Computer ... Motivation Syntactic parsing is a computationally intensive and slow task. The cost of parsing quickly be- comes prohibitively expensive as the amount of text to parse grows. Even worse, syntactic parsing is ... improve- ments that would speed up syntactic parsing. These are divided into simple software engineer- ing solutions, which are only touched on briefly, and an optimization to the CYK parsing algorithm, which...
