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 will be posted shortly.

Oct. 18	Erin Fitzgerald	J. Bresnan & R.M. Kaplan Lexical-Functional Grammar: A Formal System for Grammatical Representation The Mental Representation of Grammatical Relations, MIT Press, 1982	BTW, the edited collection that this appears in is generally interesting. 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.
