Carroll, J., E. Briscoe and C. Grover (1991) A development environment for large natural language grammars, Technical Report No. 233, Computer Laboratory, University of Cambridge.
The Grammar Development Environment (GDE) is a powerful software tool
designed to help a linguist or grammarian experiment with and develop
large Natural Language grammars. (However, it is also being used to
help teach students on courses in Linguistics and Computational
Linguistics). This report describes the grammatical formalism employed
by the GDE, and contains detailed instructions on how to use the
system.
The GDE is implemented in Common Lisp; the source code is
available as part of the `Alvey Natural Language Tools'.
