Parser Combinators for Extraction

Abstract

Dislocation phenomena in natural language can be, and often are, thought of as the effects of movement transformations. We propose to handle these phenomena in terms of parser combinators [3, 8] that transform recursive descent parsers for a 'deep structure language' into parsers for a 'surface structure language'. This combinator approach to extraction keeps close to the 'movement' intuition and gives a computational account of the well known island constraints on extraction first proposed in [7].
