manstis: I have looked at drools-chance, and my understanding is that this module is closely tied to PMML file format, I was more looking for a generic score models (additive/weighted/...) that can be defined using excel (and at some point through a custom UI).
laune: I agree that this is not a core "engine" functionality, and can be built on similar lines as the decision tables module. My original question was not phrased properly :( Now that we have covered the basics of my question, can either one of you point to any work/discussion in the drools community in this direction? Also, if I have some thoughts on this subject (creating this framework), who would be the person(s) to brainstorm? Who would provide me with a go/no-go for working on this? manstis wrote > > Doh, forgot to mention the drools-change module supports PMML. > > Helps if I join the dots up :) > > On 5 June 2012 20:55, Michael Anstis <michael.anstis@> wrote: > >> There's an experimental module called >> https://github.com/droolsjbpm/drools-chance >> >> There are various sources on the internet about using PMML for Score >> Cards: e.g. >> http://adapasupport.zementis.com/2010/02/scorecards-in-pmml-primer.html >> >> Might be worth looking at - I'm sure Davide Sotty would welcome feedback. >> >> With kind regards, >> >> Mike >> >> >> On 5 June 2012 18:40, Wolfgang Laun <wolfgang.laun@> wrote: >> >>> Thanks! >>> >>> This would not be implemented at "the Engine level"; it would be a (more >>> or less) complex >>> framework similar to what there is now (in Drools) for decision tables. >>> But the evaluation for such >>> a scorecard is much less predictable than the one for a decision table, >>> which can be >>> defined in terms of Drools Rule Language conditions, constraints and >>> actions. >>> >>> If there is a more or less straightforward way of defining constraints >>> and actions from a scorecard, >>> it might not be so much different from the approach used for decision >>> tables.
