HPSG LightHPSG Light is a version of HPSG or Sign-Based Construction Grammar (SBCG) that is sufficinetly simple to allow non-HPSG-proficient researchers to understand the analyses. It is a tool for those linguists who want to describe their insights more formally without going to the full complexity of HPSG/SBCG. HPSG Light relies on valence information specified in lists. All other aspects of the analyses are abbreviated and represented in trees. For instance the analysis of nonlocal dependencies uses a `/' in trees but no NONLOC feature and featuer passing principles.
The first HPSG Light publication is Stefan Müller's book on Germanic syntax.
