Looking for the C&C source code? I'm not affiliated with the developers of C&C and Boxer. However, one of my software packages contains it as a dependency. You can find it here: KNEWS.
The C&C/Boxer HTTP API provides an easy access to the C&C tools without the need to install software on your machine other than cURL or similar libraries for HTTP request (that usually come with the operating system anyway).
A few reasons to use the API:
I mantain an experimental installation of the HTTP API at this endpoint:
http://gingerbeard.alwaysdata.net/candcapi/
An example call is:
$ curl -d 'Every man loves a woman' 'http://gingerbeard.alwaysdata.net/candcapi/proxy.php/raw/pipeline?semantics=fol'
fol(1,not(some(A,and(n1man(A),not(some(B,some(C,and(r1patient(B,C),and(r1agent(B,A),and(v1love(B),n1woman(C))))))))))).
There is a limit of 5,000 requests/hour per client.
The source code is on github.
The service is provided as is. I do not guarantee its
continuity nor the quality of the output. Please do not rely on this
API to perform scientific experiments, I cannot guarantee the reproducibility
of the results obtained with this API. Use instead the
stable version of the C\&C tools The link to the C&C tools repository is dead.
By using this Web service you are also agreeing to the C&C System Licence Agreement and to the Boxer licence agreement (in the main directory of the C&C tools, LICENCE-BOXER.txt).
To learn about the URLs and options, read the documentation.
