Transformation-Based Error-Driven Parsing

Abstract

email brillgoldilockslcsmitedu In this paper we describe a new technique for parsing free text a transformational grammar is automatically learned that is ca pable of accurately parsing text into binary branching syntactic trees The algorithm works by beginning in a very naive state of knowledge about phrase structure By repeat edly comparing the results of bracketing in the current state to proper bracketing provided in the training corpus the system learns a set of simple structural transformations that can be applied to reduce the number of errors Af
