I want to gather a set of datasets:

  • WikiProject importance classifications
  • Count of inlinks per page
  • Page view rate per page

WikiProject importance classifications

edit

See http://quarry.wmflabs.org/query/794 (Article importance classes for English Wikipedia).

> select importance, COUNT(DISTINCT page_id) from importance_classification group by importance;
+------------+-------------------------+
| importance | COUNT(DISTINCT page_id) |
+------------+-------------------------+
| Top        |                   35639 |
| High       |                  144344 |
| Mid        |                  584461 |
| Low        |                 2359667 |
| Unknown    |                 1794587 |

Interestingly, it appears that many importance ratings are quite old. It's surprising that, for the most part, importance ratings are updated at a consistent rate. I'd suspect that most importance ratings don't change. --Halfak (WMF) (talk) 14:58, 23 October 2014 (UTC)Reply

Count of inlinks per article

edit

See http://quarry.wmflabs.org/query/806 (Inlink counts for all English Wikipedia articles).

Query is still running. I'll come back later to post an update. --Halfak (WMF) (talk) 14:58, 23 October 2014 (UTC)Reply

Page view rate

edit

This, I need to think carefully about. I'll ping a few people to see if they have worked through the implications yet. --Halfak (WMF) (talk) 14:58, 23 October 2014 (UTC)Reply
