[CWB] Assigning cqp queries

[Hardie, Andrew]

It’s not currently possible but it is on the “features to implement” list.

Unfortunately that’s a very long list….

Dear all,

a follow-up question to this. Is such a unification or intersection possible in CQPweb (e.g. with saved queries) or is this planned?

Hi Alex,

if this hasn't changed in the newest version, you can combine named queries in the following way:
A = intersection B C;   A = B ∩ C
A = union B C;             A = B ∪ C
A = difference B C;      A = B \ C

Hi Alex,

if you want to do that with the current CQP, the method I'd use (short of using the API)
would be to dump A, B and C to files (CQP writes a list of starting/ending offsets)
and then concatenate/sort these files and read them back in.
as in
A=[pos='JJ'][pos='NN']
Dump A > 'a.txt'
B=[pos='MD'][pos='VV']
Dump B > 'b.txt'
cat a.txt b.txt | sort > ab.txt
Undump D < 'ab.txt'

Best,
Yannick

Dear all,

Is it possible in CQP to assign cqp queries to new variables and then re-use them or have you thought about including something along this line to Ziggurat/CWB4? Say, I have the following queries:

A= [pos='JJ'] [pos='NN']
B= [pos='MD] [pos='VV']
C=[pos='RB'] [pos='VV']

And I would like to combine them in the following two ways:
D=A+B
E=A+C

Thanks.
Alex
