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 : ) Paul On Mon, Feb 11, 2013 at 12:56 PM, David Wood <[email protected]> wrote: > Because real data is dirty. > > Regards, > Dave > -- > http://about.me/david_wood > > > > On Feb 11, 2013, at 06:01, Vishal Sinha <[email protected]> wrote: > > Hi, > > The following resource in DBPedia: > <http://dbpedia.org/resource/Marcos_Escobedo> is a Person. > > which has a country: > <http://dbpedia.org/resource/Miguel_Hidalgo_y_Costilla> , but in fact > that is also a Person. > > How is this possible? > > > > > > > >
