The Generalized Phrase Structure Grammar (GPSG) is a grammar formalism which originated in the first half of the 80s. It was developed by G. Gazdar, G. K. Pullum et. al. as an alternative to transformational grammar which dominated research in syntax at that time. GPSG belongs to the class of unifikation-based grammars.

Comments

GPSG is a monostratal formalism: there is only one level of syntactic description and hence, there are no transformations. Each grammar can be (at least in principle) expanded into a simple context-free phrase structur grammar. Some formal problems and the growing conviction that natural languages should be considered as mildly context-sensitive which spread among linguists in the late 80s, led to a drastic loss of interest in GPSG.

Many concepts and ideas formulated within the GPSG framework (ID/LP format, head feature convention) have been incorporated by Head-Driven Phrase Structure Grammar.
