Using Adaptive Scoring

Start by using AdaptiveScoring in such a way as to mark all threads as read which you either killed or caught up.

Here is how:

 (setq gnus-default-adaptive-score-alist
       '((gnus-dormant-mark (subject 100)) 
         (gnus-ticked-mark (subject 30)) 
         (gnus-read-mark (subject 30)) 
         (gnus-del-mark (subject -150)) 
         (gnus-catchup-mark (subject -150)) 
         (gnus-killed-mark (subject -1000)) 
         (gnus-expirable-mark (subject -1000))))

The exact weights are some kind of magic, but the main point is that you want to score down anything which you didn’t like. If you don’t like threads, either kill them or don’t read them (catchup). If you do read a posting, then the subject will get a small positive score.

You can still score up your favorite authors. The default score they will get in their normal SCORE files is 1000. The ADAPTIVE score files will score down killed subjects by 1000. Therefore all the noise is marked as read while your favorite authors will continue to show up (with low scores).

Helping Out: Score Questions Up, Answers Down

Here’s a trick to help you help others:

  1. Score all articles up.
  2. Score articles with references down.

In order to not disturb any other scoring going on, use very small scores. Here are my sample rules from my ScoreFile:

 (("from"
   ...)
  ("subject"
   ("." 1 nil r)
   ...)
  ("references"
   ("." -1 nil r)
   ...)
  ("message-id"
   ...))

Use `V C’ in the Summary Buffer to enter these rules interactively.

 Subject:
  Match: .
  Score: [Value Menu] 1
  Expire: [Value Menu] off
  Type: [Value Menu] Regexp
 References:
  Match: .
  Score: [Value Menu] -1
  Expire: [Value Menu] off
  Type: [Value Menu] Regexp

You can achieve a similar effect by scoring all articles up one, and scoring all articles with a subject matching the substring “Re:” down one again. Thus, all articles with no “Re:” in the subject end up with a score of +1.

 Subjects (yes, the first entry matches the empty string -- I thinkthat makes more sense than matching the regexp “.”):
  Match: 
  Score: [Value Menu] 1
  Expire: [Value Menu] off
  Type: [Value Menu] Substring (fixed case)
  Match: Re:
  Score: [Value Menu] -1
  Expire: [Value Menu] off
  Type: [Value Menu] Substring (fixed case)
