GroupLens Scoring Score Decays
Scoring on Subjects and From headers is nice enough, but what if you're really interested in what a person has to say only when she's talking about a particular subject? Or what if you really don't want to read what person A has to say when she's following up to person B, but want to read what she says when she's following up to person C?
By using advanced scoring rules you may create arbitrarily complex scoring patterns.
