Wide-coverage parsing of speech transcripts

11th International Conference on Parsing Technology (IWPT 2009)
Paris, France, 7th-9th October, 2009

Summary

This paper discusses the performance difference of wide-coverage·¶ parsers on small-domain speech transcripts. Two parsers (C\&C CCG·¶ and RASP) are tested on speech of two different domains (parent-child language, and picture descriptions).¶ ¶ The performance difference between the domain-independent parsers and a·¶ domain-trained parsers (MEGRASP) is substantial,·¶ with a difference of about 30 percent point in accuracy. Despite this gap,¶ some of the grammatical relations can still be recovered reliably.¶
