Please read about reasoning and inference pragma use in the example at [1]. Note: my demos are live and sometimes the underlying data might change which can affect expected results, but in this case the post will show you how to map your RDF statements to an Inference Rule which then apply in-built reasoning on RDF Schema and most OWL relationship type semantics. For your example, I sense you are looking for Custom Inference Rules. If so, then you should look at [2] which demonstrates this feature. That said, the feature is part of Virtuoso 8.0 (which are are about to release, but in Commercial Edition mode only for this feature).
