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.
I would have to ask the organizers. Thanks for bringing that up to my attention
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.
I am not familiar with GATE. However, it looks to me that it is written in Java, at least that is what is said in their SourceForge page ;-) About natural language processing, I am not going to talk about it in this presentation. I decided to focus only on problems I have already worked on. In any case, natural language processing is certainly something I am interested in. So, I will be more than happy to read about any lead you have in that area.
