DEVELOPMENT OF LARGE SCALE LFG GRAMMARS: LINGUISTICS, ENGINEERING AND RESOURCESBUTT, FRANK, and KUHN |

COURSE DESCRIPTION
The course introduces students to various aspects of large-scale grammar development, including formal devices for linguistic description and abstraction in LFG, and an integration of linguistic resources, such as morphological analyzers, tokenizers, and subcategorization lexicons (including their semi-automatic acquisition).
The course material will be drawn from the lecturers' experiences in a project of parallel development of grammars over several languages. The project's "Grammar Writer's Handbook"* and other publications will serve to present implemented LFG descriptions of core syntactic constructions, and provide readings on grammar design. We further address issues of grammar engineering that arise in large-scale grammar development: testsuite design, evaluation measures, maintainability, etc. Finally, we discuss alternative approaches to large-scale grammar development and industrial applications.
The course will be accompanied by practical excercises on an LFG platform.** Starting from introductory exercises with toy grammars, more advanced exercises are based on skeletal but large grammars of English, French or German.
| * | The "Grammar Writer's Handbook" was written as part of the "ParGram" project referred to above (see http://www.parc.xerox.com/istl/groups/nltt/pargram/) |
