Thanks to Tilman for pointing out that this data is still being worked on.  So, yes, there are lots of subtleties in how we count articles, redirects, content vs. non-content, etc.  I don't have the answer to all of the discrepancies that Tilman found, but if you need a very accurate answer, the only way is to get an account on labs and start digging into how exactly you want to count the articles. 

What's the best way to signup the labs account? (does it require certain qualifications?)
And could you point us to the code or entry of the code repository?

 
As our datasets and APIs get more mature, we're hoping to give as much flexibility as everyone needs, but not so much as to drive people crazy.  Until then, we're slowly improving our docs.

And yes, don't read some of this stuff alone at night, the buddy system works well for data analysis, lol

Forwarding this question to the public Analytics list, where it's good to have these kinds of discussions.  If you're interested in this data and how it changes over time, do subscribe and watch for updates, notices of outages, etc.

Ok, so on to your question.  You'd like the total # of articles for each wiki.  I think the simplest way right now is to query the AQS (Analytics Query Service) API, documented here: https://wikitech.wikimedia.org/wiki/Analytics/AQS/Wikistats_2

To get the # of articles for a wiki, let's say en.wikipedia.org, you can get the timeseries of new articles per month since the beginning of time:


And to get a list of all wikis, to plug into that URL instead of "en.wikipedia.org", the most up-to-date information is here: https://meta.wikimedia.org/wiki/Special:SiteMatrix in table form or via the mediawiki API: https://meta.wikimedia.org/w/api.php?action=sitematrix&formatversion=2&format=json&maxage=3600&smaxage=3600.  Sometimes new sites won't have data in the AQS API for a month or two until we add them and start crunching their stats.

The way I figured this out is to look at how our UI uses the API: https://stats.wikimedia.org/v2/#/en.wikipedia.org/contributing/new-pages.  So if you were interested in something else, you can browse around there and take a look at the XHR requests in the browser console.  Have fun!

Hi Dan,

How are you! This is Victor, It's been a while since we meet at the 2018 Wikimedia Dev Summit. I hope you are doing great.

As I mentioned to you, my team works on extracting the knowledge from Wikipedia. Currently it's undergoing a project that expands language coverage. My teammate Yuan Gao(cc'ed here)  is tech leader of this project.She plans to monitor the list of all the current available wikipedia's sites and the number of articles for each language, so that we can compare with our extraction system's output to sanity-check if there is a massive breakage of the extraction logic, or if we need to add/remove languages in the event that a new wikipedia site is introduced to/remove from the wikipedia family.

I think your team at Analytics at Wikimedia probably knows the best where we can find this data. Here are 4 places we already know, but doesn't seem to have the data.

Do you know what is a good place to find this information? Thank you!

Victor

Subject: Monitor the number of Wikipedia sites and the number of articles in each site

Hi Victor,
as we discussed in the meeting, I'd like to monitor:
1) the number of Wikipedia sites
2) the number of articles in each site

Can you help us to contact with WMF to get a realtime or at least daily update of these numbers? What we can find now is https://en.wikipedia.org/wiki/List_of_Wikipedias, but the number of Wikipedia sites is manually updated, and possibly out-of-date.


The monitor can help us catch such bugs.
