crossword stuff

About two weeks ago I started thinking about making a crossword-solving AI.

http://www.cs.duke.edu/~mlittman/proverb/
http://www.cs.rutgers.edu/~mlittman/papers/aij02-proverb.pdf

My plan is to copy some of this Duke team's ideas, and make some use of Google. Perhaps it won't go anywhere, but it should be fun, at least for a while. I haven't done anything yet except collect some puzzles.

In NYT dailies from 10/23/1996 to 05/07/2006 (except for most of 1998, which for some reason was inaccessible), all but 125 of the 1015 OWL2 three-letter words appeared as answers:
AAL ABY AFF AVO AWA BUB BYS CEP CWM DAL DEV DEX DIB DUP EME FEH 
FES FET FID FIL FIZ FOH FON FOU FOY FUB FUD FUG GAE GAN GEY GID
