	Douglas Lenat - Wikipedia, the free encyclopedia
		Douglas B. Lenat (born in 1950) is the CEO of Cycorp, Inc. of Austin, Texas, and has been a prominent researcher in artificial intelligence, especially machine learning (with his AM and Eurisko programs), knowledge representation, flboard systems, and "ontological engineering" (with his Cyc program at MCC and at Cycorp).
		Lenat was one of the original Fellows of the AAAI.
		Lenat's quest, in the Cyc project, to build the basis of a general artificial intelligence by manually representing knowledge in the formal language, CycL, based on extensions to first-order predicate calculus has not been without its critics.

	microLenat
		The microLenat, originally invented by David Jefferson, was promulgated as an attack against noted computer scientist Doug Lenat by a tenured graduate student at CMU.
		Doug had failed the student on an important exam because the student gave only "AI is bogus" as his answer to the questions.
		Some of Doug's friends argue that of course a microLenat is bogus, since it is only one millionth of a Lenat.

	Arts & Leisure: The Brain Behind Cyc (Austin Chronicle . 12-28-99)
		Lenat earned a Ph.D. in computer science in 1976, but he credits his move into the field of AI to a pivotal conversation with Bobby Ray Inman in the Eighties during the genesis of the local consortium Microelectronics and Computer Technology Corp. (MCC).
		The discussion served as the catalyst for Lenat's 1984 exit from the academic cocoon of Stanford University to the Austin-based operation (initially incubated by MCC) that eventually became known as Cycorp.
		Lenat's approach to artificial intelligence is in direct contrast to his more visible brethren (and former student) Rodney Brooks of MIT, who is developing a Slinky-playing robot named Cog, who attempts to mimic human experience from a sensory-based continuum.

	Data Discussions - Meta Data meets Common Sense - An Interview with Doug Lenat
		Doug was a principal scientist at Microelectronics and Computer Technology Corporation, where he led the CYC project.
		Lenat: Integrating an external data source with Cyc effectively means making it possible for Cyc's inference engine to apply to that source an additional set of semantic integrity constraints derived from the huge amount of commonsense knowledge in the Cyc knowledge base.
		Lenat: Some of these principles have to do with economy of expression: having the totality of the content of the knowledge base (KB) be stateable as tersely as possible, introducing new terms that result in a net shrinkage of the KB footprint.

		Lenat has been steadily feeding his system facts about the world for 15 years, and reports that it's starting to get to the stage where the system can help with its own development.
		One interesting insight that Lenat reported from 15 years of work is that maintaining global consistency in the system was impossible: instead they aim for local consistency.
		Lenat concluded his talk with an announcement that CYCORP intends to progressively make elements of CYC publicly available under the banner of "OpenCYC", starting in the summer of this year, including exports of the knowledge base in DAML/XML form.

		That Doug Lenat and his 54 employees have avoided this fate is a lesson in managing long-term, visionary RandD projects.
		(Lenat hopes that Cyc will eventually be able to read unassisted.) The result: a computer that doesn’t have to be told that parents are older than their children and that people stop subscribing to magazines after they die.
		Lenat hopes that hobbyists will start adding terms, some of which would eventually be culled into the Cyc knowledge base, giving it grassroots input—and also establishing Cyc as the de facto artificial-intelligence knowledge base.

		Doug Lenat provides an example of ambiguity that must be resolved by general background knowledge in a story in which a girl sees a bicycle through a store window.
		Doug Lenat began CYC in 1984, a ten year project, with the goal of codifying all of the general background knowledge necessary for computer systems to intelligently engage in natural language communication.
		Doug Lenat claims that his prospects for the success of CYC are greater than two thirds (six times what he would have predicted in 1984).

	Cycorp: Company Overview
		Lenat knew that Cyc was too expensive for a university to fund, so he sought funds from the Microelectronics and Computer Technology Corp., a research consortium then backed by, among many others, Microsoft, Apple and the U.S. Department of Defense.
		To Lenat, the problem is simple: computers don't know enough about the real world to solve real-world problems, so you have to explain to them what it's like to be us, living in our messy landscape of grass, dirt, love, hate and shopping carts with wobbly wheels.
		Lenat, now 48, is a cheerful man, round rather than fat, with intensely twinkly eyes and brush of brown hair that swoops straight up.

		At the Austin, Texas offices of Cycorp, Lenat and his team have been working on machines that are smart, in the way that humans using common sense are smart.
		Lenat's contribution to the world is a program called Cyc (as in 'en-cyc-lopaedia'), said to be the world's largest extra-sentient body of common sense and perhaps, one day, this planet's first digital consciousness.
		It's that kind of brittleness which Lenat claims that he and his team are trying to prevent, by introducing "formalised common sense" to artificial intelligence.

		Most of Lenat's programmers are trained not in computer engineering but in fields related to logic and human thought: The staff includes about 20 philosophers and smaller teams of experts in subjects ranging from theology to physics.
		Lenat burst upon the AI scene in the 1970s with a string of now-legendary programming feats.
		Now, three years later, Lenat believes Cyc is much closer to fulfilling the role of an intelligent system that augments human capabilities, which after all is the central goal of AI research.

		Douglas B.

		Dr. Lenat was named one of the original Fellows of the AAAI (American Association for Artificial Intelligence).
		He is the President of Cycorp, the company he founded in 1994 to carry on the development and commercialization of the Cyc technology.

		Doug Lenat wrote possibly the most interesting program yet to come out of the artificial intelligence field: AM (2).
		First of all, because Doug didn't know anything about such numbers when he wrote the program, and in fact thought the program was barking up an empty tree when it went that direction.
		Secondly, because the theorems did indeed turn out to be interesting, and for awhile it was thought that this might be the first example of a computer program doing interesting original mathematics.

		Doug Lenat is endeavoring to restore the reputation of intelligent machines that HAL - the ruthless logician of 2001: A Space Odyssey - did his best to trash a generation ago.
		A former Stanford professor who has published a small library on knowledge-based systems, Lenat left academia during the mid-1980s, turning his back on what he calls "physics envy" - a myopic obsession with re-proving established theorems rather than developing systems that think for themselves.
		Now that Cyc has ingested millions of prudent nuggets, Lenat is sending his brainchild out into the world to enhance everything from search engines to spreadsheets.

		Also on the chart is Cyc, a research project sponsored by MCC of Austin and led by Doug Lenat, who has worked at Stanford since 1978 and at MCC since 1984 (see Release 1.0, 3-86).
		Longer run, there are likely to be Cycs with different "life experiences" and bodies of knowledge or expertise, but Lenat's vision is of a single reference model, since after all storage is cheap and there are few trade-offs to having all the knowledge everywhere.
		So far, says Lenat, Cyc is learning through a form of "brain surgery" -- where programmers and domain experts operate and put knowledge in wholesale.
