The first full version of the C&C tools, version 1.00, has been released! The tools consist of the C&C CCG parser -- including the computational semantics tool, Boxer -- and the C&C taggers. (The tools also use the morphological analyser morpha.)

The tools have been developed by James Curran and Stephen Clark. Boxer has been developed by Johan Bos. Both the parser and taggers are written in C++ and are efficient enough to be used for large-scale Natural Language Processing tasks.

The tools are released under an academic (non-commercial) licence. If you are interested in a commercial licence then please email

In order to download the tools you will need to register. The documentation pages contain descriptions of the tools, but please email us if there is something missing. The FAQ page contains some frequently asked questions.
