Rule engine

Hello,

If anyone is working in a rule engine we could merge efforts because I have implemented one (or something like that) for a project.

Cheers,

Hernán

I'm definitely interested in this! One of my current pet projects is
building a RETE based inference engine in Smalltalk. It's still in
pretty early stages though. Still, we might have some overlap :-)

CU,

Re: Rule engine

Cool!

I have sent an e-mail with project details.

Cheers,

I know that Herve Verjus and Marc-Philippe Huget wrote and publish a
forward and backward chainer.
Now I would be interested in a system that can also use objects for facts.
So Udo told me that he is doing a rete.
Now if I remember correctly kris gybels had a rete .

Re: Rule engine

I would be curious to hear more about the various projects mentioned in this thread. I am working on a constraint logic system that has been used as a backend for a variety of inference systems in other languages.

Thanks,
Evan

SOUL was a prolog with an extra term that unified method AST.
Check Roel Wuyts, Andy Kellens, Johan Brichau
At the VUB in the Soft (prog lab) previously the group was doing logic
meta programming.
Kris Gybels from the same group was working on Rete or may be this
is Koen deRover.

NeoPus was (not working anymore) a rule-based system that could use
object for fact and change.
I have the doc around if you want.

Herve Verjus
http://smalltalkhub.com/#!/~HerveVerjus/SmallAI
is a little project to support backward and forward chainer.

Can you explain a bit more?

Re: Rule engine

Pay attention this is just a little implementation.

You remember correctly Stef, but this was a prototype from quite a while ago, it's not on-going work. I can probably still find the code for it somewhere in my archives, but I'm not sure it's in any state where porting it from VisualWorks and merging it with current work would make much sense.
