I wouldn't go as far as "crapshoot" unless you want that particular word used out of context. Rankings such as TFIDF are very well-respected in the formal information science world. They are predicable, measurable, repeatable, mathematically sound, and very useful. The word "crapshoot" does not apply and/or the phrase "ranking is a crapshoot" needs to be qualified. -- Eric Lease MorganReceived on Mon Mar 28 2011 - 16:29:01 EDT
