The purpose of the project is the production of a course in
computational linguistics whose subject is the fitting together
of linguistic theory development, its mathematical basis, its
computational linguistic implementation and the necessary programming
methods. The linguistic framework of the course is Head-Driven Phrase
Structure Grammar (HPSG), which is one of the most important,
constraint-based linguistic theories with applications in
computational linguistics. The course introduces the mathematical
foundations of constraint-based grammar formalisms, and conveys the
knowledge essential for the formalization, implementation and
processing of natural language fragments in HPSG by investigating
concrete example grammars, their development and
usage. The connection between formal and linguistic foundations
and their application in constraint-based parsing, which
is central to the structure of the course, is executed by the grammar
implementation platform TRALE. TRALE was developed specifically for the
implementation of theoretical HPSG grammars that were not specifically
written for language processing. TRALE makes it possible to combine
formal and linguistic foundations and their treatment in one coherent
course. TRALE's techniques for language processing will be visualized
through a graphical user-interface.
