Yes, i'll let you know. btw. i received a pretty interesting message from 'davide' a few moments ago. http://www.jboss.org/tohu https://github.com/droolsjbpm/drools-chance/tree/master/drools-informer Maybe this will help you too :) > > Best regards, > > Bruno. > > Le 08/11/2011 17:43, Dirk Conzelmann a écrit : >> Hi everybody, >> >> I am using Drools as a part of my Bachelor Thesis. >> My job is to build an expert system for medical diagnoses. >> >> My Question: >> Is there a best practice known in modeling a variable >> list of questions and answers in Drools? >> >> >> Up to now I modeled the list of questions implementing >> Java Classes and Enums for each question/answer pair. >> >> But to be able to change those options easyly I need >> a higher abstraction level than simple Java Classes and Enums. >> >> >> Could someone show me an example how to implement this? >> >> >> I hope I have explained my question understandable :) >> >> > > ___ > rules-users mailing list > rules-users@lists.jboss.org > https://lists.jboss.org/mailman/listinfo/rules-users -- Dirk Conzelmann IT-Services Telefon: +49.179.2237995 Email: i...@dirk-conzelmann.de Web: www.dirk-conzelmann.de ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Data Modeling for medical expert system
Hi Davide and the other users too, thank you all for your interesting links. I´ll think that 'tohu' really seams the solution for that problem. I think it is rather interesting that after spending my first weeks on Drools reading the documentation I never saw any link pointing to 'tohu'. :) Thanks very much, I´ll share my experiences. Despite from being interested in this aproach, I have to adjust my tasks for being able to finish my Bachelor Thesis in the given amount of time.

[rules-users] Data Modeling for medical expert system
Hi everybody, I am using Drools as a part of my Bachelor Thesis. My job is to build an expert system for medical diagnoses. My Question: Is there a best practice known in modeling a variable list of questions and answers in Drools? Up to now I modeled the list of questions implementing Java Classes and Enums for each question/answer pair. But to be able to change those options easyly I need a higher abstraction level than simple Java Classes and Enums. Could someone show me an example how to implement this? I hope I have explained my question understandable :) -- Dirk Conzelmann IT-Services Telefon: +49.179.2237995 Email: i...@dirk-conzelmann.de Web: www.dirk-conzelmann.de ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
