Head-Driven Phrase Structure Grammar

This page provides information about activities related to the grammatical framework of Head-Driven Phrase Structure Grammar (HPSG) at the Center for the Study of Language and Information (CSLI) and the Department of Linguistics at Stanford University.

The HPSG Project conducts its activity under the umbrella of CSLI's Linguistic Grammars Online Project, which has developed various large-scale HPSG grammars. These grammars have blended into HPSG a number of features taken from work in Berkeley Construction Grammar. The resulting synthesis is the emerging framework of Sign-Based Construction Grammar (SBCG), as developed in:

  • DELPH-IN Project. Computational linguists of research sites world-wide have joined forces in a collaborative effort aimed at deep linguistic processing of human language. The goal is the combination of linguistic and statistical processing methods for getting at the meaning of texts and utterances. The partners have adopted Head-Driven Phrase Structure Grammar (HPSG) and Minimal Recursion Semantics (MRS), two highly advanced and influential models of formal linguistic analysis. They have also committed themselves to a shared format for grammatical representation and to a rigid scheme of evaluation, as well as to the general use of open-source licensing.
  • DeepBank The DeepBank project has the goal of annotating the one million words of 1989 Wall Street Journal text (the same set of sentences annotated in the original Penn Treebank project) with the English Resource Grammar, augmented with a robust approximating PCFG for complete coverage. DeepBank contains rich linguistic annotation on both syntactic and semantic structures of the sentences and is available in a variety of representation formats.
  • FUB German Grammar Group Stefan Mueller's group in Berlin has developed numerous resources for the HPSG-based analysis of German and various other languages. These are based on the TRALE System, developed at the University of Tuebingen.
