Algorithm[edit | edit source]
- Let's iterate the revisions' list of an article sorted by rev_id DESC (from table "revision")
- First iteration has a weight=0.8^i and the number i (starts with 0) increments with following iterations if weight>0.0001.
- We can avoid rounding errors with this limit. These weights are so tiny that we can leave them.
- Rated revision (has a row in articlescores table) has a score:
- S = sum of stars of this revision / number of votes.
- Not rated revision has a score S = 0.
- R: rating of the article
- w: weight = 0.8^i. If revision is not rated, w(i)=0.
- i: iteration step, starts with 0
- S: rating of a revision
As soon as some edit on a rated article is done, the rating gets recounted.
Notes[edit | edit source]
- Tested with Vector skin only
- Main page is excluded from rating.
SpecialPage[edit | edit source]
SpecialPage:ArticleScores diplays best, worst, or articles with selected rating. The are sorted by the score. Articles with score 2 have in fact 1,5 - 2,4999. There is no paging, I assume that only top articles in the selected filter are interesting. Number of items displayed can be set in AS_SPECIAL_ITEMS, see Configuration section.
