KR Engines

Hi,

Can someone recommend a good Knowledge Representation engine that works with LW 5.1? I have heard of OpenCyc, KM and PowerLoom. OpenCyc appears quite heavy weight for me. Any personal experience with these or other engines? I am looking for a toolkit that can be used in a commercial application.

Thanks for your help.

Regards,

Rangarajan

LispWorks Enterprise bundles 'KnowledgeWorks'.

I'm not sure how OpenCyc works 'with' LispWorks. Usually you want either a) the KR engine integrated into Lisp or b) running as a server with a Lisp API to access the server. AFAIK a) is not supported by OpenCyc and b) one has to write? Not sure about the latter.

RacerPro runs as a server. There is also a more expensive version that can be loaded into Lisp.

Re: KR Engines

I am extremely fond of Loom (not PowerLoom, but its predecessor). I used Loom in 2000 to build a network fault-analysis engine at Fujitsu; it works very well with LispWorks, and Tom Russ of ISI is first rate if you need support.

Re: KR Engines

I've recently been looking at Cyc, OpenCyc, ConceptNet and WordNet.

From the OpenCyc / CycL FAQ:
"In what way is it possible to use OpenCyc together with a lisp-environment like Xanalys LispWorks?
We have a socket interface that handles lists. The entire API is lispy. So it would require opening a socket and writing/reading SExprs."

I also looked at CyN which is Cyc + AIML Program N.

Then there's ACT-R which includes WNLexical as an interface to WordNet:

http://act-r.psy.cmu.edu/about/

And there's Double R Theory using ACT-R for Natural Language:

http://www.doublertheory..com/index.html

FWIW.

Re: KR Engines

ACT-R is a cognitive architecture, not a KR system. It can be used for KR, but the paradigms are very different.

Of course, KR itself.  http://www.cliki.net/KR

And you can always use CLOS to represent your knowledge, with the
added advantage that it often can be directly use in inference
engines, such as LISA.
