Re: [rules-users] How does drools provides an explanation of how the solution was arrived?

Note that in the RHS of any rule you can use    kcontext.getRule().getName() and    kcontext.getMatch().getObjects() to explain which rules were fired with which match objects.

Rules engines are made up of human readable rules, as opposed to say a neural network where the knowledge isn't explicitly represented (it's a big black box of maths). A rules engine is symbolic, a neural network sub-symbolic. A neural network can give you an answer, but not a justification of why. People like rules engines because (when done properly) they can see why it has given the answer it has given. To answer your question, to get a explanation of what the rules engine did, you could insert a logging object as a global into your rules session and then add a log statement in the conclusion of each rule. -- View this message in context: http://drools.46999.n3.nabble.com/How-does-drools-provides-an-explanation-of-how-the-solution-was-arrived-tp4026253p4026263.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
