Grammar Formalisms and Parsing The A4 project is dedicated to the designing of a course in computational linguistics, the fitting together of linguistic theory development, its mathematical basis; computational linguistic implementation, and its necessary programming methods. The focal point of the web-based course developed here is the TRALE-system for the implementation of fragments of natural languages in Head-driven Phrase Structure Grammar (HPSG). with computationalhpsglinguistic
Parallel Grammar Project The Lexical Functional Grammar (LFG) ParGram and ParSem projects are a collaborative effort involving researchers in industrial and academic institutions around the world. The aim of the ParGram project is to produce wide coverage grammars for a wide variety of languages. These are written collaboratively within the linguistic framework of LFG and with a commonly-agreed-upon set of grammatical features. The ParSem project develops semantic structures based on the ParGram syntactic structures. Most of the ParSem systems use XLE's XFR system. with computationalgrammarlinguisticsparallelsyntax
XPAR [Language Diversity and Parallel Grammars] The goal of XPAR is to determine to what extent the development of parallel deep grammars for typologically diverse languages may support the automatic derivation of high-quality parallel treebanks for those languages. These treebanks could in turn be suitable for a deeper theoretical understanding of the ways in which syntactic functions, semantic roles and translation are interrelated. XPAR intends to further develop computational grammars for Georgian, Tigrinya and Dutch based on common principles and covering all central constructions in the languages, with an existing grammar for Norwegian as a pattern. with computationalsyntaxtreebank
