Abstract
We describe a simple approach for integrating
shallow and deep parsing. We use phrase struc-
ture bracketing obtained from the Collins parser
as filters to guide deep parsing. Our exper-
iments demonstrate that our technique yields
substantial gains in speed along with modest
improvements in accuracy.
1 Introduction
The detailed linguistic analyses generated by deep
parsing are an essential component of spoken dia-
log systems that collaboratively perform tasks with
users (e.g., (Allen et al., 2001)). For example, inter-
pretation in the TRIPS collaborative dialog assistant
