Course 3

LFG Grammar Development and Semantic Construction (XLE and XFR)
2 - 3.30pm

Miriam Butt (Universität Konstanz) and Richard Crouch (Powerset Inc., Microsoft)

This course introduces powerful state-of-the-art grammar development software that includes interfacing with finite-state morphological analyzers, integrating large scale lexica, an interaction between a rule-based syntax and statistically-based disambiguation methods, a generator (all of this is part of XLE) and a very powerful and flexible rewriting system (XFR), which has been used for purposes of machine translation as well as semantic construction. The first half of the course introduces the student to basic grammar writing techniques within XLE on the basis of the architecture assumed by Lexical-Functional Grammar (LFG; Bresnan and Kaplan 1982, Butt et al. 1999, Dalrymple 2001, Butt et al. 2006). The second half of the course introduces XFR and will focus mainly on the uses of XFR for semantic construction (as machine translation is the focus of the course by Forst and Fraser; Crouch and King 2006, Butt and King 2007).
