[rules-users] Re: Re: Newbie: Is this feasible w/ Drools?
Edson,
Thank you for your prompt reply.
It's good to know that I can dynamically add rules to a rulebase.
With regard to a 'rule hierarchy', I'm actually referring to the fact
that our assertions often build on each other. I'd really like to be
able to define the rules only once, but be able to see the (sub-)
rules and facts that make up an assertion.
E.g:
'Glutathione Biosynthesis' is asserted YES if we have both 'Glutamate-
Cysteine Ligase' AND 'Glutathione Synthetase'.
'Glutamate-Cysteine Ligase' is asserted YES if we find any of 4
different annotations (facts).
'Glutathione Synthetase' is asserted YES if we find any of 2
different annotations (facts).
We need to see all assertions related to an annotation, all the way
up the inference chain. Likewise, since we'd like to define the rules
only once (in Drools), it's important to be able to see all the steps
that made up the inference chain to 'Glutathione Biosynthesis'.
Thanks,
Alex
P.S. What's a POC?

Alexander,
Seems a really interesting project indeed!
Trying to answer:
1. I'm not sure what you mean by "rule hierarchy". Drools does not
support rule "inheritence" if that is what you mean by hierarchy...
can
you please ellaborate?
2. Dynamically adding rules to a rulebase will not force a full
reevaluation. Only the new rules are evaluated and if they eventually
have Patterns that may be shared, they are not even evaluated, as they
already were.
The problem I think you will face is that Drools does not support
uncertanty reasoning. You will need to code uncertanty by hand if you
use drools. I suggest you a POC to check how it goes.
