[CWB] a question regarding the keywords analysis in CQPweb

[Ray Wu]

Dear members,

It is known that currently CQPweb sets a "Min freq"  constraint for keyword analysis.  Isn't it possible that "Min freq (list 2):" could be zero in some cases? Why should the lowest number of "Min freq (list 2):" be set to 1 instead of zero?

Thanks for any pointers to relevant literature.


Best,
Ray
