No. The first line of the Wikipedia text contains '{{Infobox award'.
The mapping for 'Infobox award' has a
'map to class' for
http://mappings.dbpedia.org/index.php/OntologyClass:Award, which in
turn has rdfs:subClassOf owl:Thing.

'map to class' basically means
$(article containing this template) a $(class to map to) .
which, in this case, is OntologyClass:Award, and, because that
contains an rdfs:subClassOf, owl:Thing.

'absolute-line' refers to the Wikipedia text.
