Any users of Harlequin's KnowledgeWorks? Screamer?

[Kaelin Colclasure]

I am contemplating a project that will involve a fairly straightforward
inferencing component, and I wondered if and KnowledgeWorks (KW) users
might be lurking about. And especially any KW users who are also familiar
with Screamer and might offer their opinions of how the two compare.

I played a bit with Screamer somewhen back in the mists of antiquity, but
never did get all of it quite working. (I think I was using CMUCL on SunOS
at the time.) The functionality was perfect for what I have in mind -- but
if KW offers similar capabilities off-the-shelf with support, I'd
rather buy it than try to port Screamer.

Hello Kaelin. Some six months or so ago I evaluated KW; as a platform for
building "traditional" rule-based systems it seemed to be just fine. As a bit
of background, I migrated a component from our KBS used for network element
simulation; KW offered the constructs necessary to do the port successfully.

I can't help you with Screamer, but you might also consider having a look at
Loom (http://www.isi.edu/isd/LOOM/LOOM-HOME.html). I'm currently using this
platform for some advanced modeling and reasoning, and it seems quite powerful.

Regards,

What parts of Screamer didn't work under CMUCL/SunOS? I might be able to help
fix it.

Thanks for the info -- and the pointer to LOOM. I'll have a look. I'm waiting
to hear back from the Harlequin folks anyway...

Jeff,

Mea culpa -- after posting my article I recalled that it was ACL/Win 3.1
that I was unsuccessfully trying to coax into swallowing Screamer. It
worked fine (as far as I explored) with CMUCL/SunOS.

ACL/Win has since undergone a major overhaul by Franz, and is now vastly
more compatible -- but this project I want hosted on Solaris, and right
now I don't have *any* CL implementation there. (A situation which I plan
to rectify.) :-)
