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 : )

Ideally, there should be derivative or cleans of this ontology that could be contributed back to the project. Once these exist, incorporation and exploitation is trivial. Thus, see this as another aspect of the project that welcomes contributors :-)
