Hi,
I am creating a local RDF store, and storing some information in it
myself.
For example,
- "Angela Merkel is a Chancellor"
- "Barack Obama is a President"
In DBPedia ontology it is stated that,
Chancellor is subclass of Politician. President is also subclass of
Politician.
When I make a SPARQL query to my local RDF store, I want to get
inference result according to DBPedia
OWL ontology.
In this case, if I ask give me all politicians, it should give me -
Angela Merkel and Barack Obama.
My Question: Should I keep a copy of DBPedia ontology in my RDF
store? Or what else could I do?
Thanks.
For inference to work the underlying axioms need to be processed.
Thus, you will need to read the DBpedia ontology, one way or the other.
Short answer: Yes.
