easy with the build instructions :)<br>

Yes I'm trying to do an integration. I have some experience with
ontologies and want to experiment with drools as an alternative.<br>
<br>
OWL with reasoners like Fact ++ are pretty much good for the job,
except for the fact that they handle individual data bits in quite
a cumbersome way. It was because of this reason that I wanted to
experiment on other ways of modeling a knowledge structure with
better facilities for querying large amounts of factual data. I'm
giving drools a try, but I'm not entirely sure if drools can do
things as powerful as a reasoner.<br>
<br>
Basically, I'd like to be able to let the data lie (without firing
any "events" until necessary) and query the inferences in a
first-order logic like manner. This is very space-efficient in
data-heavy scenarios. I know that this isn't the traditional way
drools is designed to work. I'm trying to solve the inference
problem by dynamically adding semantic classes to each object to
store all the possible inferences about it, so they can be queried
later. Problem with this approach is that it gets out of hand very
quickly, because the enumerated number of such inferences can be
HUGE even for a moderate KB. Backward chaining will eventually
solve this problem, but it seems that the constructs available for
that in drools queries are not too matured at the moment. For
instance they don't seem to support numerical inequality operators
(or I am wrong, which is also very likely).<br>
<br>
Thank you again for the quick help,<br>

<pre wrap="">You should be able to
git clone ...
the droolsjbpm repository, then
git checkout -t origin/5.5.x
this should switch to 5.5.1-SNAPSHOT (you can check the pom in the root
folder)
eventually, mvn clean install should do the trick.
See also the readme.md in github
Btw, it seems that you're working with rule/ontology integrations..
would you
be interested in sharing thoughts?

<pre wrap="">Hi Davide,
Thanks a lot for the information and your time spent on troubleshooting the
scenario with a test case.
I'm using 5.5.0; as I mentioned, I'm a newbie. I'll try to get 5.5.1
compiled and running (on windows), I'm reading whatever the documentation I
can find on how to do this. Github source seems to be on 6.0.0, I'll try
with that one if all else fails.
I'm loading the rule base using a KnowledgeBuilder, and yes I do check for
errors explicitly after building. The rule file with the problem I mentioned
does not produce any errors, other than the result that doesn't make sense.
Thanks again,
Upali
