Extensible Dependency Grammar: A New Methodology

Abstract

This paper introduces the new grammar formalism of Extensible Dependency Grammar (XDG), and emphasizes the benefits of its methodology of ex-plaining complex phenomena by interaction of sim-ple principles on multiple dimensions of linguis-tic description. This has the potential to increase modularity with respect to linguistic description and grammar engineering, and to facilitate concurrent processing and the treatment of ambiguity. 1
