Wikidata seems to be highly queried by now, it is a public endoint.
However, the query bellow might work in RDFSlice:
ps: notice that the subject variable (?article) contains the wikipedia link
and it will be extracted.
SELECT *
WHERE
{
?article <http://schema.org/description> ?o .
?article <http://schema.org/about> ?o1 .
?article <http://www.w3.org/2000/01/rdf-schema#label> ?o2 .
}
best,
Edgard
