Hi !

I'm looking for a algebrical formula that sould be already used and would
allow to get the weight of a criteria according to its frequency in a
documentation database.

For instance, if a word is cited only once, its weight should be arround 1
if another is cited in all articles, its weight should be arround 0

Thanks is you have any suggestion or reference (Web or paper)

best regards.

please reply to : frantz.thiessard@free.fr
