Abstract

We present a parsing algorithm for arbitrary context-free and probabilistic context-free grammars based on a representation of such grammars as a combination of a regular grammar and a grammar of balanced parentheses, similar to the representation used in the Chomsky-Schützenberger theorem. The basic algorithm has the same worst-case complexity as the popular CKY and Earley parsing algorithms frequently employed in natural language processing tasks.
