FUDG Framework for Syntactic Annotation

Fragmentary Unlabeled Dependency Grammar (FUDG) is a formalism that offers a flexible way to describe the syntactic structure of text. Beyond the traditional view of dependency syntax in which the tokens of a sentence form nodes in a tree, FUDG allows for a distinction between nodes and lexical items; provides special devices for coordination and coreference; and facilitates underspecified annotations where producing a complete parse would be difficult. Graph Fragment Language is an ASCII-based encoding of unlabeled dependency annotations in the FUDG formalism.
