database that can be even run at real time??


I think you misunderstood my email. I was not saying that WDQ cannot be 
used. I was merely asking you how one could use it, as I am not aware of 
any method to get the information that we display from this tool 
(certainly not through the Web interface, but I am not familiar with any 
other).

Can you explain this a bit more? How would I use the WDQ database for 
this application? (I guess you don't mean via the Web API)


Thanks,

Hi,

We are looking into options of making this faster, but this might
need a full rewrite to become really fast. The good thing is that
loading only has to happen once per month (until the next data update).

There is a known issue with character encoding now, leading to "?"
in some labels/descriptions. We are looking into it.

Another new feature is that we now also count properties used on
property pages:


http://tools.wmflabs.org/wikidata-exports/miga/#_cat=Properties/Uses%20in%20properties=1%20-%202

Compared to the old data, we have a lot more objects in some classes
now (it's amazing how many asteroids, first names, bands, and legal
cases there are ...). It seems we have more than 10,000 galaxies on
Wikidata already.

Here are our top-100 classes by number of instances:


http://tools.wmflabs.org/wikidata-exports/miga/#_cat=Classes/Number%20of%20direct%20instances=1%20-%201000

Other classes have a lot of subclasses rather than instances:


http://tools.wmflabs.org/wikidata-exports/miga/#_cat=Classes/Number%20of%20direct%20subclasses=1000%20-%2020

And of course, as usual, you can browse individual properties to see
the classes of objects they are used on ("What kind of things have a
diameter?") and browse classes to see which properties are typical
for them ("What kind of statements do we have about poems?").

Cheers,

Markus

Hoi,
Would it be possible to have other data to compare it with. When you see a
delta, you can understand about the developments in the data. Single data
views while of interest do not inspire people to work even more on their
favourite topic.

Mine would be for now P166.
Thanks,
 GerardM

Hi all,

there  are some good news: I updated the Miga Classes and Properties 
Browser which collects several statistics about classes and properties 
used in Wikidata. In the future it will be updated monthly.


You can find it here: http://tools.wmflabs.org/wikidata-exports/miga/
