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:
