Re: A new use for Spamprobe - Interestingness vsHo-hum Boring

In theory this makes sense, but in practice I dont think it would work that 
well for spamprobe ...
Spamprobe has been highly tuned with the understanding of Spam and Ham (not 
"Category A" and "Category B") in that it makes many decisions which favor 
Ham over Spam under the (very correct IMHO) assumption that its better to 
categorize a spam as ham then visa-versa.
Even without making N>2 this theory breaks down if you use arbitrary 
categories.
Makeing N>2 categories is even harder ... because the algorithms used 
collapse to a single number ...

A mult-dimensional bayesian filter could likely do the trick , but trying to 
get spamprobe to do it, I suggest, is not going to be so easy ... or 
desirable.
