CGELBank Annotation Manual v1.2
It provides a resource for computational linguistics researchers working on English syntax, but it is incremental as it builds on an existing grammar.
The paper presents CGELBank, a treebank and tools for English syntax based on the Cambridge Grammar of the English Language, detailing its annotation scheme.
CGELBank is a treebank and associated tools based on a syntactic formalism for English derived from the Cambridge Grammar of the English Language (CGEL; Huddleston and Pullum, 2002). It is hosted on GitHub at https://github.com/nert-nlp/cgel. This document lays out the particularities of the CGELBank annotation scheme.
