Grammar Development in Constraint-Based Formalisms
Formalisms: HPSG and LFG

Jonas Kuhn and Stefan Müller

This course is an introduction to Head-driven Phrase Structure Grammar (HPSG) and Lexical-Functional Grammar (LFG). The key concepts of both approaches are motivated by linguistic analyses and both approaches are compared. Basic mechanisms to deal with phrase structure and valence are introduced and the following phenomena are studied: nonlocal dependencies, German clause structure, coordination, lexical alternation.

The course consists of both a theoretical part and a practical one. The participants will implement some of the analyses during the sessions. Particular grammar development problems will be addressed also: corpus oriented development, test methodology, lexicon development, morphology, and ambiguity resolution. At the end of the course participants should be able to write a non-trivial grammar for a constraint-based parser.
