Ockham’s Razor is Dull

Saturday, June 14th, 2008

It's all (well, mostly) about representation. Peter Turney: [F]iguring out how to represent the problem is 95% of the work. By the time you have the representation right, the tool that you use to finish the remaining 5% is not terribly important.

What’s the opposite of ‘hype’?

Wednesday, September 26th, 2007

There must be an antonym for 'hype.' To hype something is to engage in hyperbole about it: Apple products have generated their share of hype. (For example: Steve Jobs said, "We made the buttons on the screen look so good you’ll want to lick them.") I don't mean 'anti-hype' ...

Why the New Yorker cartoon caption contest winners are not especially funny

Wednesday, August 29th, 2007

Here's a QA with the primary gatekeeper to the New Yorker cartoon caption contest: Q. Did your predecessor or Bob give you any advice when looking through the responses? A. My predecessor stared me in the eyes and warned me that reading too many captions in one sitting could make a man ...

Actually, a little more robot overlordship than I’m currently experiencing would be nice

Thursday, May 17th, 2007

Sitting down to dinner, I said something like today I wrote a program that wrote a program, and its running righ now. Daughter and wife looked slightly alarmed, and dear wife asked if there were any chance that I was working myself out of a job. I said I didn't ...

Quotes on names (2)

Saturday, May 5th, 2007

The uniqueness and immense pragmatic convenience of proper names in our language lie precisely in the fact that they enable us to refer publicly to objects without being forced to raise issues and come to agreement on what descriptive characteristics exactly constitute the identity of the object. They function not ...

When Mr N.N. dies, one says that the bearer of the name dies, not that the meaning dies. -- Wittgenstein, Philosophical Investigations

WordNet, saints and Robin Hood

Saturday, April 28th, 2007

Why are you reading this, when you should be reading Natalia’s ball-peen hammer to the head? One of the many things that it takes for a computer to “understand” text (as we are trying to do at Powerset) is for it recognize names and what they refer to. So for example, ...

Semantic Parser, best in show

Friday, April 27th, 2007

I got an email today from Larry Hunter at University of Colorado School of Medicine, who writes to say that a DMAP-based parser was the "international world-champion" in the The BioCreAtIvE (Critical Assessment of Information Extraction systems in Biology) data text mining challenge. The chart above are the results from ...

Powerset in NY Times, Venturebeat

Friday, February 9th, 2007

The company I work for, Powerset, is being written up in the New York Times and Venturebeat, both reporting on a deal between Powerset and PARC. The New York Times article (behind a registration wall, alack) mostly follows the storied arc of the Palo Alto Research Center, where the graphical ...

Thursday, October 13th, 2005

From Samuel Butler's The Book of the Machines in Erewhon:Complex now, but how much simpler and more intelligibly organised may [a machine] not become in another hundred thousand years? or in twenty thousand?

Borges: a whale of an error

Monday, October 10th, 2005

I received an email from Justin Bur that says (quoting with permission): Your English version of Borges' celebrated essay http://www.entish.org/essays/Wilkins.html contains a rather spectacular mistranslation based presumably on a typo in the original Spanish. Section 16 of Wilkins' taxonomy classifies the *whale*, not beauty, as a viviparous oblong fish. There ...
