Wikipedia:Version 1.0 Editorial Team/Selection trials

From Wikipedia, the free encyclopedia

This page is an archive which chronicles the tests run by the SelectionBot. Early bot work was done by User:MartinBotII, but when this bot became unavailable for 1.0 work it switched to User:VeblenBot.

[edit] First trial (

A pilot trial was conducted using articles from chemistry, physics, medicine and mathematics, and this generated these results:

This pilot trial used the simple algorithm described here:

  • Quality:
  1. FA-Class is 7.5
  2. A-Class is 6.5
  3. GA-Class is 5
  4. B-Class is 4.5
  5. Start-Class is 4
  6. Stub-Class is 2
  • Importance:
  1. Articles that are needed for completeness will have their importance rating doubled
  2. Top-importance is 7.5
  3. High-importance is 6
  4. Mid-importance is 4
  5. Low-importance is 2.5

The rating of an article is its quality rating times its importance rating. Articles which have a rating of 20 will automatically be included in the release version. (This includes top importance that are at least start class, high-importance that are at least B-class, mid importance that are at least GA-class; and no low importance).

Score Importance
Top High Mid Low
7.5 6 4 2.5
Quality
Featured article FA 7.5 56.25 45 30 18.75
A 6.5 48.75 39 26 16.25
Good article GA 6 45 36 24 15
B 4.5 33.75 27 18 11.25
Start 4 30 24 16 10
Stub 2 15 12 8 5

NOTE: the minimum rating can be increased to get better articles (at the expense of quantity) or decreased to get more articles (at the expense of quality).

The test was considered to be a great success - it generated a very viable selection of articles.

[edit] January 2007 trials

Results:

Trial running now (slowly), banding the links-in "score" (average importance of the links in) into four bands, roughly the same as the other system's values (anything with an average below 20 gets a score of its links-in rating /10). I'm using a multiplier of 0.9 for all projects again, and the scores themselves are being printed to the bot tables. Due to a slight hiccup by me, I'm not running a trial on the chemistry project right now, but will rectify the situation when I can. For WP: maths, we've got a lot more articles, so the threshold of 20 may need to be raised. I'm just waiting for the others to finish now... (we're up to Physics - the last and longest one).
