Hi,

I found that WDQS misses several sitelinks. I tried to query sitelinks via SPARQL:

PREFIX schema: http://schema.org/ SELECT ?qid { https://en.wikipedia.org/wiki/Argon schema:about ?qid }

This works for the Wikipedia URL given above, but many other don't return a result, for instance:

https://en.wikipedia.org/wiki/Getty_Thesaurus_of_Geographic_Names => should be http://www.wikidata.org/entity/Q1520117

https://en.wikipedia.org/wiki/BioPAX => should be http://www.wikidata.org/entity/Q4914639

https://en.wikipedia.org/wiki/Mathematics_Subject_Classification => should be http://www.wikidata.org/entity/Q967960

I also tried querying the other way round:

PREFIX schema: http://schema.org/ SELECT ?site{ ?site schema:about http://www.wikidata.org/entity/Q967960 }

It looks like the Blazegraph database does not contain all sitelinks.

Yeah it looks like Stas noticed as well and already has this task open to reload it: https://phabricator.wikimedia.org/T115549

Hi!

This works for the Wikipedia URL given above, but many other don't return a result, for instance:

https://en.wikipedia.org/wiki/Getty_Thesaurus_of_Geographic_Names => should be http://www.wikidata.org/entity/Q1520117

This one is actually recorded as https://en.wikipedia.org/wiki/Getty%20Thesaurus%20of%20Geographic%20Names

Not sure if it's a problem or not. But the sitelinks should be updated now.
