NLP Reading Group

The reading group attempts to keep abreast of current trends in natural language processing research. We typically read one or two recent NLP conference papers each week, and occasionally look at material from the machine learning, statistics, and linguistics communities as well.

Starting in 2008, we will be posting the weekly readings here. Past readings since 2001 are being filled in presently.

Spring 2008

First meeting of the term will be on Thursday, Jan. 31, at noon in NEB 317. Feel free to bring lunch.

Propagation for approximate inference: An empirical study. , 15th UAI, pages 467-?75, 1999

... discussing (loopy) belief propagation as background for survey propagation, a topic which has been getting more attention lately for its ability to "solve very large hard combinatorial problems, such as determining the satisfiability of Boolean formulas.

Chapter 8 of Chris Bishop's textbook is supposed to be a good treatment of graphical models overall. It is available free here [1]. He covers BP in section 8.4.4 after first presenting factor graphs in 8.4.3. , David MacKay's treatment of BP, also in terms of factor graphs, is in chapter 26 of his book [2]. It's worth reading this chapter in full, perhaps first reading chapter 16. ... the update equations are given as (26.11) and (26.12) ... [substantial further discussion by jason was here]

Some people may prefer Bishop's style, others MacKay's.

Bresnan defends and develops lexicalized grammars in general; the idea of separate surface and semantic roles; and Bresnan & Kaplan's LFG in particular. You should know that she originated (in 1978) the extremely influential idea of lexicalized syntax -- the idea that a grammar is simply a collection of lexical entries to be assembled in standard language-independent ways, but that there are also "lexical redundancy rules" that relate, e.g., active and passive entries for the same verb. Some chapters address morphological and cognitive issues pertaining to lexicalization, including an essay by Pinker on lexicalist learning. , Slides from Erin's presentation can be found here. , Oct. 11 (John Blatz) L.Xu, D.

In Optimality Theory: Phonology, Syntax and Acquisition Oxford University Press 2000 Feb. 12 (Brock) Bob Frank, Giorgio Satta , Optimality theory and the Generative Complexity of Constraint Violability , MIT Press A glimpse (from MIT Press): , It has been argued that rule-based phonological descriptions can uniformly be expressed as mappings carried out by finite-state transducers, and therefore fall within the class of rational relations. If this property of generative capacity is an empirically correct characterization of phonological mappings, it should hold of any sufficiently restrictive theory of phonology, whether it utilizes constraints or rewrite rules. In this paper, we investigate the conditions under which the phonological descriptions that are possible within the view of constraint interaction embodied in Optimality Theory (Prince and Smolensky 1993) remain within the class of rational relations. We show that this is true when GEN is itself a rational relation, and each of the constraints distinguishes among finitely many regular sets of candidates. , Feb. 19 (David Smith) Barzilay and Lee , Learning to Paraphrase: An Unsupervise Approach Using Multiple-Sequen7:12 PM 2/4/2008ce Alignment , HTL 2003 Mar. 5 (Charles Schafer) Daniel Marcu , Theory and Practice of Discourse Parsing and Summarization, Chapters 2 & 3 , The MIT Press, 2000 Mar. 18 (Markus Dreyer) Eugene Charniak, Niyu Ge, John Hale A Statistical Approach to Anaphora Resolution Proceedings of the Sixth Workshop on Very Large Corpora, 1998 Mar. 25 (Eric Goldlust) Boyan and Moore , Learning Evaluation Functions to Improve Optimization by Local Search , Journal of Machine Learning Research, 2000 Apr. 3 (Roy Tromble) Roman Bartak , Constraint Programming: In Pursuit of the Holy Grail , 1999 Apr. 10 (Noah Ashton Smith) Denys Duchier , Axiomatizing Dependency Parsing Using Set Constraints , Sixth Meeting on Mathematics of Language, 2000 Apr. 10 (Noah Ashton Smith) Denys Duchier , Axiomatizing Dependency Parsing Using Set Constraints , Sixth Meeting on Mathematics of Language, 2000 Apr. 17 (Elliott Franco Drabek) Rina Dechter , Mini-Buckets: A General Scheme for Generating Approximations in Automated Reasoning , 2001 Apr. 24 (David Smith) McCallum and Jensen , Extraction and Data Mining using Conditional-Probability, Relational Models , IJCAI'03 Workshop on Learning Statistical Models from Relational Data, 2003 The paper is a survey of recent trends in IE and data mining (biased of course towards the authors' work) and a proposal to unify them with conditional random fields. , May. 1 Izhak Shafran Eric J.
