Determining the importance of items across sets?
$begingroup$
There's a better term for it. Let's say i have a suite of sets - A, B, C, D.
Each set contains any number, in a non-important order, of items - 1,2,3,4,5,6 The items may occur any number (0 or more) of times in a set.
Is there some agreed-upon formula to determine the "most important" item? Or are there algorithms for this?

The question makes no sense unless you tell us your definition of "most important".

@DavidC.Ullrich oh! good one! I don't know, i was honestly hoping there would be an algorithm for that. i'm settling for tf-idf, but is there anything else to consider?
