When I run your code, among the several triples added I see
(rdflib.term.URIRef('http://example.org#Avatar'), rdflib.term.URIRef('
http://schema.org/keyWords'), rdflib.term.URIRef('http://example.org#Sam'))
If you turn off inference, it is the only triple added. So perhaps some
sort of an environment issue.
