Extensible Dependency Grammar ( XDG ) is a new grammar theory based on dependency grammar .

XDG analyzes natural language expressions along an unlimited number of independent dimensions, e.g. B. grammatical function, word order , predicate-argument structure, scope , prosody and information structure. Each of these dimensions is subject to a set of well-formedness conditions, the one-dimensional principles, e.g. B. valence . In addition, the relationship between several dimensions is determined by a number of multi-dimensional principles such as climbing or linking.

XDG grammars can be implemented using the XDG Development Kit (XDK), which provides a large number of tools for easy grammar development, including a parser and a graphical user interface .
