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

    <rdf:subject resource="#r1" />
    <rdf:predicate resource="foo:confidence" />

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

IIRC, your exmaples are b-nodes.
