Description

The implementation of linguistically-based grammars for natural languages draws on a combination of engineering skills, sound grammatical theory, and software development techniques. This course provides a hands-on introduction to the methods and tools needed for building the precise, extensible grammars required both in research and in applications. Through a combination of lectures and in-class exercises, students will investigate the implementation of constraints in morphology, syntax, and semantics, working within the unification-based lexicalist framework of Head-driven Phrase Structure Grammar.

Topics to be addressed in the course include: the use of types and features, multiple inheritance, lexical rules, and constructions. Daily implementation exercises will be conducted in the freely-available LKB grammar development platform, and will include experience with adding and repairing lexical types, lexical entries, lexical rules, phrase structure schemata, and compositional semantic constraints. While most of the course work will focus on small-ish grammars for English, we expect to apply our jointly acquired grammar engineering expertise to at least one other language towards the end of the week.

Registration

Course registration will be limited, since this will be a highly interactive, hands-on course. Mail your registration to siegel@dfki.de. Since the number of places is limited, attendance is compulsory after registration. The last day for registration is 7 April 2004, unless all places have been taken earlier.

Exercises 1, 2, 3 and 4 5, 5b 6 7 8
Grammars 1 and 2 the Grammar Matrix 0.6

This material is closely based on the material prepared by Petter Haugereid for a course on using the Matrix grammar. Further, we borrowed some material from Emily Bender on the same topic. Included is also LKB course material developed by Ann Copestake, Dan Flickinger, Rob Malouf, and Stephan Oepen.

Possible topics for Scheine

Based on the grammar matrix (/proj/contrib/lkb/stable/src/data/matrix0.6 on head), develop

Before you start on a topic, come and talk to us about the language, the phenomena and the coverage. Make a test suite (a list of sentences as in test.items) and come and discuss it with us.
