Portal stats.wikimedia.org can now be searched

Wikimedia stats portal stats.wikimedia.org now features more tools and reports than ever (57 and growing). An often heard complaint was that the portal was a bit overwhelming and hard to navigate.

Two changes hopefully help you find what you need with more ease. First all entries are now in one huge list, no artificial breakdown between internal and external tools. By itself this list may be even more daunting in size, but the new search feature aims to address just that.

You can now filter entries by keywords. Descriptions and search tags will be scanned. The search then returns a table of content, followed by qualifying full entries.

Like before each entry briefly describes a few highlights of the tool, and features a rather small screenshot. This screenshot is not meant to explain the tool or report in detail (it may even be hard to read). Its function is twofold: primarily it can help you find back a report which you used earlier, and which you may still recognize from its visual appearance. It also gives a clue for at a glance scanning for type of output, e.g. tables vs charts.



* Primary objective was to make the current portal easier to use with limited coding effort, short payback time. Any more substantial overhaul is not ruled out, but currently not on the agenda of the Wikimedia Analytics Team.
* Any feedback is of course welcome: suggestions for functional improvement, for entries to add, for keywords to add, for fixing minor layout quirks.
* Current focus is on publicly accessible tools and reports. None of the entries leads to a page which requires log in.
* You’ll find an entry for Wikipedia visualizations, but those can’t be searched individually (yet).
* Even some defunct reports are listed (but clearly marked as such). Partly because some of these are dearly missed and can serve as inspiration for future replacements.

Full archive dumps are being processed again, first since 2010

There is not Wikistats issue for which I received more mails than this: since 2010 some metrics on article content were no longer updated: word count, articles above 200 chars, mean size in bytes, percentage above 0.5 or 2 Kb, database size, word count, images and links (internal, interwiki, external). Word count in particular was often mentioned.








Example: Polish Wikipedia

All these metrics need to be collected from the ‘full archive dumps’, the dumps which contain the full raw content of every revision of every page. The sheer amount of data that needs to processed made it no longer feasible to process those full dumps on a monthly basis (it didn’t help that I do rather ambitious cleaning up of the raw page content before counts are generated (e.g. for word count to approach ‘readable body text’).

So in 2010 for most Wikipedias I switched to processing stub dumps, which contain all meta data for every revision, but not the raw page content. For sister projects with much smaller dumps I continued processing full archive dumps.

Now finally I can announce I applied a fix which makes it possible to update those missing metrics roughly on a quarterly cycle. Full archive dumps are now processed on a different server, running as continuous low priority job, and the reporting process combines metrics from both servers.

In the last two weeks some 260 wikis were processed. Only 10 large wikis remain to be done:  Arabic, English, French, German, Hebrew, Italian, Japanese, Spanish, Swedish, Russian.  I expect in a month time all but English will be ready. English may arrive -fingers crossed- a month later.

Wikimedia editor trends broken down by project

Since a few years we present monthly deduplicated totals for active and very active editors. Deduplicated meaning: every editor only counts once, regardless of number of wikis edited. We never collected similar trends on a per project basis. So to make up for this, last week I ran some special iterations of Wikistats to collect active editors trends per project.

I want to share with you four charts, as they were presented at today’s Metrics Meeting. There will be a follow-up study, but here are a few quick observations:

1) First chart is the big picture,

  • where English editor community is still somewhat shrinking (but most of that happened earlier)
  • where all non-English Wikipedias combined are fairly stable
  • where non-Wikipedias combined show significant growth especially in 2013

2) Second chart focuses on two largest non Wikipedia projects: Commons and new project Wikidata (together these make up most of the orange line in first chart).

Note how the large peaks in Commons editorship in September are result of hugely successful Wiki Loves Monuments contests

3) Third chart shows smaller Wikimedia projects which are stable or growing

4) Fourth chart shows smaller projects which are slightly or significantly shrinking

Thanks to Dario Taraborelli for inquiring about these metrics. He and I will look into this further, possibly checking correlation with page view trends.

Total editors on Wikipedia compared with same on all Wikimedia wikis

New Edit and Revert Stats

Finally on popular request edit/revert stats will now be generated each month for all Wikimedia projects. For the largest Wikipedias some new charts are already online: English, Japanese, German, Spanish, Russian, French, Dutch. Other wikis will follow in coming weeks.

For each wiki there will be a separate page with charts and tables. Charts come in two variations: raw data and trend lines (this may see overkill, but on some wikis one variation is more readable than the other, depending on line patterns) . Tables tell you what kind of content is reverted most, for which users, and by which users and bots.

Some examples:

Edits and reverts on English Wikipedia
The sharp peak in bot edits in 2013 is caused by the migration of interwiki links to Wikidata. You will see in coming months that on many wikis bot edit counts will decline to far below Dec 2012 level, as most interwiki bots stopped working.
Revert ratio on Dutch Wikipedia

On many wikis there is a very distinct seasonal pattern for revert ratio. Here you see how on the Dutch Wikipedia far less anonymous edits are reverted in summer, and a bit less around Christmas. Most probably there is less vandalism in those periods, as schools are closed. Perhaps there are also less edit patrollers on duty during vacations, and more bad edits slip through?
Revert ratio on Spanish Wikipedia

On the Spanish Wikipedia the dip in revert ratio occurs every half year. Same goes for the Portuguese Wikipedia (new charts not yet available). There is a simple explanation: both wikis are edited intensely in the northern and southern hemisphere, with different holiday seasons.
