[CWB] CQPweb

Sure is! :o)  I've been running it on my laptop for several weeks now  
and I'm very happy with the system.

Andrew already answered this -- to seasoned BNCweb users it's obvious  
that you can change the query language with the little button below  
the entry field ...

I'd like to add that CQPweb's simple query language is also intended  
as a standard for CWB Web interfaces. It's called CEQL, and the  
implementation is part of the new Perl modules.

The new Perl modules have been split into separate packages that can  
be installed independently with different dependencies (e.g. you need  
a C compiler for CWB::CL, but you the CWB base package including  
CWB::CQP is fully platform-independent and has very few prerequisites).

I'm planning to release (part of) the WebCqp code as a separate  
package (because it depends on some other modules that are not  
essential for the basic CWB/Perl interface), but it'll be some time  
before I get round to updating it.  You should be able to use the old  
WebCqp modules with a few small modifications, though (I'm doing this  
with my own installations of the CQP demo).


Concerning your original question:

No, it's not publically available.  Like all Web interfaces at this  
address, it's a hacked version of the CQP demo scripts tailored to a  
specific corpus, and does not offer any straightforward configuration  
options.

It should be relatively straightforward to do that, just as with the  
original CQP demo that you adapted for OPUS (but not any easier).   
I've already removed some of the extra frills from the first CQP demo  
in the Europarl version, so the code is actually a little bit cleaner.

If you want, I can send you a ZIP archive with the code, but without  
documentation (and you'll have to piece the paths together yourself,  
which are all set to what I need for my own installation).  Same offer  
holds for everyone else, of course.

Best wishes,
Stefan
