I dont think thats reified (though I'm not that hot on RDF syntax), I
think reified statements look something like:

  <rdf:Statement>
    <rdf:subject resource="#r1" />
    <rdf:predicate resource="foo:confidence" />
    <rdf:object>65%</rdf:object>
  </rdf:Statement>

representing one triple. But it doesnt entail the "obvious" triple.

IIRC, your exmaples are b-nodes.
