Well, it looks like no one else will answer so I'll give it a shot.
Several other rulebase systems (all of them commercial and quite
expensive) actually do what they call a "gap analysis" - which is
nothing more than considering all of the attributes and possibilities
and combinations and then telling you which ones you left out. Which
ones you should put in, at that point, is left up to you. Usually
the ones that you left out aren't important in small systems but can
be quite expensive if you're trying to design a large, enterprise
system for a financial company who can't afford to lose out on a
single rule that is put out on the internet for the entire world to
try and hack into.
In the meantime, may I suggest this: Put the rules into a
spreadsheet (not the best way to do this but it works for small rule
sets) and then look at the outcomes. On rule per spreadsheet.
Remember, if each condition element is true or false, then you will
have 2^n rows, or rules, for each rule that could become a ruleset.
If there is an attribute (CE) that has 3 possible answers, leave it
out of the 2^n calculation and then just multiply the 2^n result by
3. (Or 4 or whatever...) What you'll find is that you might have a
possible combination of 80K or 100K rules where you had originally
thought that there were only 100 rule combinations.
Admittedly, a lot of these rows (rules) can be removed by
combinations and some of them might be highly unlikely or might have
no bearing on the output - but, on the other hand, they might and
should be considered.
Like I said, not the best way to do a "gap analysis" but it works for
small rules with few condition elements.

Hi, all
I want to do rule refinement base on jess, or we can say verify
completeness and consistency in rule-based of jess. Has someone
done that
before? Can you guys give me some advise or info about that, thanks!!
Look forward to your reply.
