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.

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