I have written a paper about Topic Detection and Tracking, where I also
explain the TF-IDF-scheme. If you like, i can send you the paper.

Hello,
I was recently looking thru the lucene in action book and came across
the
scoring formula. I was wondering if the formula has changed since the
book
was written?
Also was wondering if someone can breifly explain what the IDF(t) term
in
the formula means? In the book it says that it's the inverse document
frequency of the term but doesn't explain beyond that?
thanks,
rajiv
