lets do KDD...

Hay the call for KDD cup is up at official site.
I have registered for that, but until I finishes my project, I can't think about that. I have friends with me in our team. This time very interesting task is up. Classify the search queries. You have been given a long(800000 queries) list of search queries, now classify them into one of the 74 predefined queries. Now you a query of around 2-3 words, ya, nothing else, tell me which category it belongs to?
