Sadly not. We don't have proper structured meta-data yet. That's what the
Structured Data on Commons project is about:

You can also use the Wikimedia Commons API made by Magnus:
https://tools.wmflabs.org/magnus-toolserver/commonsapi.php

It will also gives you metadata about the image (so you'll be able to cite
the author of the image when you reuse it).

The actual value of the statement is just the image name itself (in this
case “0 A.D. logo.png”), the c.w.o/wiki/ link is only generated for the
HTML view. You can get the path to the actual file using
Special:FilePath on Commons; for instance, the RDF export of the entity
(https://www.wikidata.org/wiki/Special:EntityData/Q161234.ttl) contains
the statement wd:Q161234 wdt:P18
.

That's not exactly straightforward, given you have to make a query for
every single file (or batch of up to 50 of them), but you can get the
URL through the API. In this case:

https://commons.wikimedia.org/w/api.php?action=query&format=json&prop=imageinfo&iiprop=url&titles=File%3A0_A.D._logo.png

Thanks a lot all who are involved, very interesting.

However, when I look at the statistics of usage,

http://wdcm.wmflabs.org/WDCM_UsageDashboard/

I see that Wikivoyage allegedly uses, in particular, genes, humans (quite a
lot, actually), and scientific articles. How could this be? I am pretty
sure it does not use any of these.

[Wikidata] Wikidata Concepts Monitor

2017-10-30 Thread Lydia Pintscher 
Hey folks :)

As you might already have seen in the birthday presents list there is
another birthday present: the Wikidata Concepts Monitor (WDCM -
http://wdcm.wmflabs.org). It is a tool that enables you to browse and
build an understanding of the way Wikidata is used across the
Wikimedia projects.

Here’s the technical gist behind it: Currently 789 projects have
client-side Wikidata usage tracking enabled, which allowed us to built
a system that counts the number of pages using a particular Wikidata
item per project. The count data were subjected to statistical
modeling (1) by an unsupervised statistical learning algorithm -
https://en.wikipedia.org/wiki/Latent_Dirichlet_allocation (2) that is
typically used in distributional semantics -
https://en.wikipedia.org/wiki/Distributional_semantics (3) to discover
the most natural groupings of Wikidata items in 14 semantic categories
- https://en.wikipedia.org/wiki/Topic_model (4) in respect to the way
they are used across the Wikimedia universe by the respective
communities.

We hope for the WDCM system to become a tool that helps you discover.
Beyond Wikidata’s syntax and semantics we are now beginning to learn
about its pragmatics: the way Wikidata items will cluster in respect
to how they are used is not necessarily the same as the way they go
together in the Wikidata formal ontology. WDCM is the first step
towards building an understanding of the highly complicated structure
of Wikidata usage. This system can help you discover what Wikidata
client projects are similar and in what respect, what semantic
categories of items are used more or less frequently across 789
projects, how do items connect in respect to how similarly they are
used by our communities, what are the most popular items per project,
and many more (hopefully) interesting things.

Check out the WDCM and don’t forget to let us know what you think on
the WDCM Wikidata project discussion page! I'd love to hear about any
cool or interesting things you find in the visualizations.
https://www.wikidata.org/wiki/Wikidata:Wikidata_Concepts_Monitor

Thanks to Goran who put in a lot of time to get this up and running
and everyone who helped him.

[Wikidata] WikidataCon & Wikidata birthday

2017-10-30 Thread Léa Lacroix 
Hello all,

As you know, this weekend we celebrated Wikidata's fifth birthday, during
the WikidataCon in Berlin, but also in Tokyo, Seoul and Munich.

We collected a lot of amazing *presents and stories*, that you can find
here: https://www.wikidata.org/wiki/Wikidata:Fifth_Birthday

During the WikidataCon, 200 members of the community met, shared their
knowledge, experiences, favorite tools, and discussed about a lot of
topics. We're currently trying to document the outcomes of the conference
as best as possible. You can already find some content on:
* the video recordings of the sessions happening in room A
https://media.ccc.de/b/conferences/wikidatacon/2017
* the slides and notes of each session of day 1
https://www.wikidata.org/wiki/Wikidata:WikidataCon_2017/Documentation/Proceedings
* the Commons category & subcategories
https://commons.wikimedia.org/wiki/Category:WikidataCon_2017

We are also very happy to announce that the *WikidataCon will be back in
October 2019 in Berlin*, to host even more attendees and more exciting
content.

In 2018, we encourage all the local communities to organize their own
events around the sixth birthday, in order to build a *Wikidata birthday
around the world*. Meetups or trainings, conferences or parties, big or
small, all the ideas are welcome to celebrate Wikidata with your local
community and engage new editors. More information will come in the next
months, but you can already mention your projects on this page:
https://www.wikidata.org/wiki/Wikidata:Sixth_Birthday
