Hi Vishal
if you are loading the instance data and the dbpedia ontology into a triple
store that has RDFS reasoning capability then its because the ontology
properties that are typically defined with domains and ranges are misused
throughout the dbpedia instance data - which causes instances to be
inferred to be the wrong class types. This is prevalent throughout - its a
bit of a mess to say the least.

The ontology is best used just as a loose reference guide, not to reason on
: )
