RFC: Presentation on Machine Learning with Perl
Sounds quite interesting. Any chance of videotaping it? You could put it on your site, YouTube (though low res), or Zudeo, or democracy player, etc. I enjoyed watching video on my iPod of sessions I missed at YAPC::Asia, although the code projected on the screen was too small to see. Certainly a bunch of videos on interesting subjects in Perl could be a great way to introduce people to it.
By the way I did a survey of natural language parsing programs in Perl a while back just as an initial dip into it, but never actually had an opportunity to use those tools. I don't remember if it is Perl (a lot are Java but I think this is not) but have you used the uk program GATE and are you going to talk about that sort of thing (head parsing, automatic categorization/chunking, extraction of key noun phrases, etc.)? I am not familiar with the apps you are talking about but am quite interested in how to easily incorporate machine learning into my Perl systems.
