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.
