Subject: [Wikidata-l] Birthday gift: Missing Wikipedia links (was Re:
Wikidata turns two!)
To: Discussion list for the Wikidata project. <
wikidata-l(a)lists.wikimedia.org>gt;, Wikimedia Mailing List <
wikimedia-l(a)lists.wikimedia.org>
Folks,
as you know, many Googlers are huge fans of Wikipedia. So here’s a little
gift for Wikidata’s second birthday.
Some of my smart colleagues at Google have run a few heuristics and
algorithms in order to discover Wikipedia articles in different languages
about the same topic which are missing language links between the articles.
The results contain more than 35,000 missing links with a high confidence
according to these algorithms. We estimate a precision of about 92+% (i.e.
we assume that less than 8% of those are wrong, based on our evaluation).
The dataset covers 60 Wikipedia language editions.
Here are the missing links, available for download from the WMF labs
servers:
https://tools.wmflabs.org/yichengtry/merge_candidate.20141028.csv
The data is published under CC-0.
What can you do with the data? Since it is CC-0, you can do anything you
want, obviously, but here are a few suggestions:
There’s a small tool on WMF labs that you can use to verify the links (it
displays the articles side by side from a language pair you select, and
then you can confirm or contradict the merge):
https://tools.wmflabs.org/yichengtry
The tool does not do the change in Wikidata itself, though (we thought it
would be too invasive if we did that). Instead, the results of the human
evaluation are saved on WMF labs. You are welcome to take the tool and
extend it with the possibility to upload the change directly on Wikidata,
if you so wish, or, once the data is verified, to upload the results.
Also, Magnus Manske is already busy uploading the data to the Wikidata
game, so you can very soon also play the merge game on the data directly.
He is also creating the missing items on Wikidata. Thanks Magnus for a very
pleasant cooperation!
I want to call out to my colleagues at Google who created the dataset -
Jiang Bian and Si Li - and to Yicheng Huang, the intern who developed the
tool on labs.
I hope that this small data release can help a little with further
improving the quality of Wikidata and Wikipedia! Thank you all, you are
awesome!
Cheers,
Denny

Hey folks :)
Today Wikidata is turning two. It amazes me what we've achieved in
just 2 years. We've built an incredible project that is set out to
change the world. Thank you everyone who has been a part of this so
far.
We've put together some notes and opinions. And there are presents as
well! Check them out and leave your birthday wishes:
