Hi Dave, Thanks, this makes my task harder :-) Let me then ask you a question about the rules that I have. Maybe you can help me with this. Based on the same example that we were talking I want to create a rules that are executed when "I have sign A, B (compulsory) and one of the following: C, D, E). For this, I already have a solution creating several combinations such as A,B,C; A,B,D; etc.. but I want other design.
I've then some rules where, first of all, I close the world using noValue and specifying only A,B,C,D, and E as valid signs. Then, I've created a rule that should be fired (with diagnosis result) only if I have A, B (compulsory) and a counter with a value greater or equal to 1. Then, I've developed also three more rules (one per remaining sign: C,D,E), that increases this counter. However it seems to not be working. Here are the rules: http://pastebin.com/LeWY7Ndq PD: The counter doesn't exist in my current ontology. It is created in the same way than hasNegSign. Thanks! _______ Sorry no. There are sophisticated rule systems that can tell you why a rule wasn't fired but there's no support for that in JenaRules. Dave
