We had an really wonderful session today with Dr. Douglas Lenat, 
President & CEO of Cycorp. Dr. Lenat's talk was on "CYC: Lessons 
Learned in Large-Scale Ontological Engineering." After 21 years 
and $75 million dollars on the endeavor, what Dr. Lenat had to 
share with us today were true words of wisdom on the subject.    (01)

Thank you very much, Doug, for sharing your work and insight
with us. Thanks are also due to my fellow Ontolog co-conveners, 
Kurt Conrad, for making the invitation to Dr. Lenat on behalf of 
the community, and Leo Obrst, for opening our session with an 
introduction of Doug to our community. And, as always, 
appreciations to all who came, participated and helped contribute 
to yet another great Ontolog session.    (02)

The digitized (mp3) audio recording of the entire discussion has
now been posted. (I have already edited out the few phone 
connection snags we had during the session.) That will be 
archived in our knowledge repository for reference and download 
by anyone interested. See details at:
Doug's input today adds true value to this collective knowledge 
and intelligence that our community is building.    (03)

Thanks & regards.  =ppy    (04)

P.S. Please note that there will not be any Ontolog conference 
call next Thursday since it falls on a major US holiday. *Happy 
Thanksgiving*, to all our US membership. Our next couple of major 
events have already been lined up:    (05)

On Thursday, Dec. 8, 2005, Dr. James Spohrer, Director of 
Services Research at IBM's Almaden Research Center will be our 
invited speaker for December, and will be presenting to the 
community. The title of his talk will be: "Services Science, 
Management, and Engineering (SSME)." ... Please refer to details 
on the wiki session page at: 
  and then,    (06)

on Thursday, Dec. 15, 2005,  Mr. Duane Nickull and Mr. Kurt 
Conrad will be moderating a Technical Discussion Session on 
"Ontology Applications and Implementations". Be on the look out 
for further announcements relating to this event.    (07)

Mark your calendars ... and, RSVP if you are planning to join us 
on the Dec. 8 Jim Spohrer talk.  =ppy

> The pursuit of Artificial Intelligence -- from robotics to natural

> "brittleness bottleneck" caused by the need for common sense.  For 21 
> years, we've been priming the pump, building up a formalized corpus of 
> such knowledge, Cyc.  Along the way, we've had to revise our 
> preconceptions and theories, to expand our representation language and 
> arsenal of inference methods, to find approximate yet adequate 
> engineering solutions to problems that philosophers have grappled with 
> for millennia such as ontologizing aspects of substances versus 
> individual objects, time, space, causality, belief, social interactions, 
> and so on. The process of ontological engineering had to grow and evolve 
> throughout this enterprise, as well, such as how Cyc represents and 
> reasons with contradictions and context.
> In this talk I will try to cover both the large scale picture of what 
> we've built and why, and the detailed picture of how it's built, and the 
> lessons learned along the way in how and how not to do large-scale OE.  
> I will report on our recent efforts to make Cyc more accessible to the
