AtD uses a lot of memory but this technique made a difference speeding up the spell checker. For things best done with a hash lookup, we use hashtables. This is what we're using for generating edits still (I wrote most of this post in August 09, finally finished it today). [Edit: I wrote Sleep :) I don't promote it much but it's been with me for many years and I've applied it to a lot of problems including the NLP in AtD]

Sweet. I tried doing a similar experiment targeting C++ years ago but never finished it. Nicely done! How far along is it? Writing Perl-ish code that targets the JVM seems inspired to me. Object oriented? Can write threaded code and all that? (there's been a number of times where Perl's shortcomings in those areas have prevented me from building better code).

  It's not OO but you can roll your own. See: http://sleep.dashnine.org/manual/functions.html#3 http://sleep.dashnine.org/manual/functions.html#3 It does threading using a fork(&function) abstraction. You can pass an initial set of variables to share but otherwise it's shared nothing. The fork returns an I/O handle which you can use to communicate values back and forth (even serialized objects). You can also wait(fork(&function)) to get a return value when the thread finishes. The Manual, covers the whole language: http://sleep.dashnine.org/manual/ http://sleep.dashnine.org/manual/ An article talking about some of the fun things to do with continuations: http://today.java.net/pub/a/today/2008/07/24/fun-with-continuations.html http://today.java.net/pub/a/today/2008/07/24/fun-with-contin...
