The ParGram and ParSem projects are collaborative efforts by researcher groups in industrial and academic institutions around the world.

The aim of ParGram is to produce wide coverage grammars for a variety of languages. These are written collaboratively within the linguistic framework of LFG (Lexical Functional Grammar) and with a commonly-agreed-upon set of grammatical features. The XLE (Xerox Linguistic Environment) is used as a development platform.

ParSem develops semantic structures based on the ParGram syntactic structures. Most of the ParSem systems use the XLE’s XFR system.

Regular semiannual meetings are being held to bring together the various research groups involved in ParGram and ParSem.
