- A. Lavie, C. Rosé. 1998. A Domain Independent Approach for Efficiently Interpreting Extragrammatical Utterances. Abstract: In this paper we address the issue of eeciently and eeectively handling the problem of extragrammaticality in a large-scale spontaneous spoken language system. We propose and argue in favor of ROSE, a domain independent parse-and-repair approach to the problem of interpreting extragrammaticalities in spontaneous language input. We argue that in order for an approach to robust interpretation to be practical, it must be domain independent, eecient, and eeective. Where previous approaches to robust interpretation possessed one or two of these qualities, the ROSE approach uniquely possesses all three. We evaluate our approach by comparing its performance in terms of parse time and quality 2 Ros e and Lavie with a parameterized version of the minimum distance parsing (MDP) approach as well as with a more restrictive partial parser, two alternative domain independent approaches. Our analysis demonstrates that the ROSE approach performs signiicantly faster than a limited version of MDP, while producing analyses of superior quality. We also demonstrate that the two stage ROSE approach achieves a higher level of quality in less time than a more restrictive partial parser. We believe these results support the claim that in general two stage approaches like ROSE achieve high quality results more eeciently than one stage approaches.
