hello friends
is there a way in LOD data to query for underlying ontology structure ?
eg. say i want to find some information about "population of
australia" from LOD data. i can figure out that australia is a
country by many different means but before resolving this query i
would like to know from LOD if a country does have population
property/predicate or not. this is to filter out queries like
"pupulation of chairs". is there a way in LOD to query if the
countries ( or its class type) has population attribute before moving
ahead to find the answer to query ?
thanks

Ravinder,
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 :-)
Of course you could have also just gone to the "URI Lookup (by Label)"
and then types in: population. The result would be an auto-complete
style list of all Classes, Prorperties, and Instance Data URIs that have
pattern: population, in their labels :-)
