Hi all.

I need to get IDF values for an American corpus of at least 100MW words. I have access to TREC4 and TREC5 corpus but would prefer to not have to extract the information 'manually' and was wondering if there are IDF values out there already calculated from a large corpus. If not, are there any tools for extracting IDFs efficiently?

Regards,
