In Computational Linguistics, we can choose between different grammar formalisms as linguistic description devices. The formalisms differ with respect to their suitability for linguistic descriptions, their expressive power and their implementability.
In this course, we will concentrate on Tree Adjoining Grammar, a grammar
formalism which at the same time offers a clean account of a wide range
of linguistic phenomena and is particularly well suited for grammar
implementation and parsing. We will compare Tree Adjoining Grammar to other grammar formalisms used in Computational Linguistics, such as LFG, CCG and HPSG.
For students needing 9 credits, an additional seminar is offered by Stephan Kepser. See here.
