The paper first introduces key notions in language modeling and probabilistic parsing, and briefly reviews some previous approaches to using syntactic structure for language modeling. A lexicalized probabilistic top-down parser is then presented, which performs very well, in terms of both the accuracy of returned parses and the efficiency with which they are found, relative to the best broad-coverage statistical parsers. A new language model that utilizes probabilistic top-down parsing is then outlined, and empirical results show that it improves upon previous work in test corpus perplexity. Interpolation with a trigram model yields an exceptional improvement relative to the improvement observed by other models, demonstrating the degree to which the information captured by our parsing model is orthogonal to that captured by a trigram model. A small recognition experiment also demonstrates the utility of the model. <\/jats:p>","DOI":"10.1162\/089120101750300526","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T11:55:01Z","timestamp":1027770901000},"page":"249-276","source":"Crossref","is-referenced-by-count":112,"title":["Probabilistic Top-Down Parsing and Language Modeling"],"prefix":"10.1162","volume":"27","author":[{"given":"Brian","family":"Roark","sequence":"first","affiliation":[{"name":"Brown University, Department of Cognitive and Linguistic Sciences, Box 1978, Brown University, Providence, RI 02912"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"281","reference":[{"issue":"1","key":"p_3","first-page":"25","volume":"19","author":"Briscoe Ted","year":"1993","journal-title":"Computational Linguistics"},{"issue":"2","key":"p_4","first-page":"275","volume":"24","author":"Caraballo Sharon","year":"1998","journal-title":"Computational Linguistics"},{"issue":"2","key":"p_12","first-page":"299","volume":"24","author":"Chi Zhiyi","year":"1998","journal-title":"Computational Linguistics"},{"issue":"8","key":"p_17","first-page":"451","volume":"6","author":"Earley Jay","year":"1970","journal-title":"Communications of the ACM"},{"issue":"3","key":"p_26","first-page":"315","volume":"17","author":"Jelinek Frederick","year":"1991","journal-title":"Computational Linguistics"},{"issue":"4","key":"p_28","first-page":"617","volume":"24","author":"Johnson Mark","year":"1998","journal-title":"Computational Linguistics"},{"key":"p_29","first-page":"535","author":"Johnson Mark","year":"1999","journal-title":"grammars.
