This tutorial overviews basic ideas of TAG/ CCG/LFG/HPSG, and provides attendees with a comparison of these formalisms from a linguistic and computational point of view. We start from stating the motivation behind using these expressive grammar formalisms for NLP, contrasting them with shallow formalisms like contextfree grammars. We introduce a common set of examples illustrating various linguistic constructions that elude context-free grammars, and reuse them when introducing each formalism: bounded and unbounded non-local dependencies that arise through extraction and coordination, scrambling, mappings to meaning representations, etc. .
