In this paper we take up the question posed by the results of <cite>Sporleder and Lapata (2005)</cite> : how much, if any, accuracy reduction should we expect if we choose to use only finite-state derived features, rather than those derived from full contextfree parses? If little accuracy is lost, as their results suggest, then it would make sense to avoid relatively expensive context-free parsing, particularly if the amount of text to be processed is large or if there are real-time processing constraints on the system.
