ACL ID C10-2123
Title Argument Optionality in the LinGO Grammar Matrix
Venue International Conference on Computational Linguistics
Session Poster Session
Year 2010

We present a library of implemented HPSG analyses for argument optional- ity based on typological studies of this phenomenon in the world’s languages, developed in the context of a grammar customization system that pairs a cross- linguistic core grammar with extensions for non-universal phenomena on the ba- sis of user input of typological proper- ties. Our analyses are compatible with multiple intersecting phenomena, includ- ing person, number, gender, tense, aspect and morphological rule formulation. We achieve 80-100% coverage on test suites from 10 natural languages.
