Using constraints over finite sets of integers for range concatenation grammar parsing

Abstract

Range Concatenation Grammar (RCG) is a formalism with interesting formal properties (it has a polynomial parsing time while being more powerful than Linear Context-Free Rewriting Systems). In this context, we present a constraint-based extension of the state-of-the-art RCG parsing algorithm of [1], which has been used for the implementation of an open-source parsing architecture. © 2008 Springer-Verlag Berlin Heidelberg.
