Head-driven phrase structure grammar

The Head-Driven Phrase Structure Grammar (HPSG) is a grammar theory developed by Carl Pollard and Ivan A. Sag (1985) in the tradition of the transformational-generative grammar. It is the immediate successor to Generalized Phrase Structure Grammer. HPSG draws from other fields as well like computer science - data type theory and knowledge representation and uses the notion of sign (Ferdinand de Saussure). It uses a uniform formalism and is organized in a modular way which makes it attractive for Natural language processing.

A HPSG grammar includes principles and grammar rules and lexicon entries which are normally not considered to belong to a grammar.

The basic type HPSG deals with is the sign. It has two features: PHON (the sound, the phonetic form) and SYNSEM (the syntactic and semantic information), both of which are split into subfeatures.
