#2 about calculate association rules

[zhouby]

I want to use ConExp to mine association rules based on
concept lattice. I have read some papers on this issue.
Most of them define Duquenne-Guigues basis for exact
association rules and Luxenburger basis for approximate
association rules. I have done some testing, and I found
that ConExp cannot find all Luxenburger basis for
approximate association rules. So can someone tell me
what the definition of association rules in ConExp?
I think usually each edge in concept lattic should be a
approximate association rule if we set very low minsup
and minconf.

Thanks,
