: '''Abstract (by Doug Lenat):'''

: '''The pursuit of Artificial Intelligence -- from robotics to
natural language processing to automated learning -- has been
held back by the "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 broader community
through OpenCyc and [[ResearchCyc]], which raises issues of how
multiple individuals and groups can share and integrate their
extensions (and settle their differences). Finally, I will
discuss an exciting new effort we have just had funded, to
gather automated reasoning researchers together for a series
of workshops in 2006 on speeding up inference in large
knowledge bases by orders of magnitude.'''

* '''Session Format and Agenda''':
** ''this will be virtual session over a phone conference setting, augmented by shared computer screen support''
** The session will start with a brief introduction of the online attendees (~10 min.)
** [[LeoObrst|Dr. Leo Obrst]], Ontolog co-convener, will introduce our guest speaker, [[DougLenat|Dr. Douglas Lenat]].
** Presentation by the invited speaker (45~60 min.)
** Open discussion (30~45 min.)

* '''Bio of Dr. Douglas Lenat''':

: '''Dr. Douglas Lenat''' is the President and CEO of Cycorp. Since 1984, he
and his team have been constructing, experimenting with, and applying
a broad real world knowledge base and reasoning engine, collectively "Cyc".
For ten years he did this as the Principal Scientist of the MCC research consortium
(the Microelectronics and Computer Technology Corporation), and since 1994
as CEO of Cycorp. He holds BAs in Mathematics and Physics and an
MS in Applied Mathematics from the University of Pennsylvania. His 1976
Stanford Ph.D. thesis was a demonstration that certain kinds of creative
discoveries in mathematics could be produced by a computer
program (a theorem ''proposer'', rather than a theorem ''prover''). That work earned
him the bi-annual IJCAI Computers and Thought Award in 1977. Dr. Lenat was
a professor of computer science at Carnegie-Mellon University and at Stanford
University. He is one of the founders of AAAI (the American Association for
Artificial Intelligence), and a Fellow of AAAI. He has authored hundreds of journal
articles (e.g., a four-article series in ''AI.J.'' over several years on ''The Nature of
Heuristics I-IV''), book chapters (e.g., in ''Machine Learning'' and ''Hal's Legacy'')
and books (including ''Knowledge Based Systems in Artificial Intelligence''
and ''Building Large Knowledge Based Systems''). In 1980 he co-founded
Teknowledge, Inc. His interest and experience in national security has led him
to regularly consult for several U.S. agencies and the White House. He is the
only person to have served on the technical advisory boards of both
Microsoft and Apple.
