Using LOD Cloud Cache instance at: <http://lod.openlinksw.com> I was 
able to use pattern: Australia Population, to produce: 
http://lod.openlinksw.com/fct/facet.vsp?cmd=load&fsq_id=3032  (I just 
use "Type" and "Property" filtering on the initial results). You will 
notice there are properties from DBpedia and Geonames data spaces 
associated with the pattern :-)
