To be clearer, the resulting OWL RDF has

Andy,
I'm having trouble getting rid of all my ^^ noise.
I run Jena schemagen against an Ontology that has no type annotations,
I don't see any in the output of schemagen, but calls to
entityRef = model.createIndividual(entityUri, oclass);
entityRef.addLiteral(Rex.hasEntityDetectionSource, source);
entityRef.addLiteral(Rex.hasNormalizedText, normalizedText);
entityRef.addLiteral(Rex.hasOriginalText, rawText);
end up adding the ^^ and the string data type.
If you look at the Javadoc for Resource.addLiteral, there's no
overloaded type signature for addLiteral( Property, String ). Which
means that you're actually invoking this method:
http://openjena.org/javadoc/com/hp/hpl/jena/rdf/model/Resource.html#addLiteral(com.hp.hpl.jena.rdf.model.Property,%20java.lang.Object)
which says:
"""
Add the property p with the typed-literal value o to this resource, ie
add (this, p, typed(o)) to this's model. Answer this resource. The typed
literal is equal to one constructed by using
this.getModel().createTypedLiteral(o).
"""
You want either:
entityRef.addProperty(Rex.hasEntityDetectionSource, source);
or
entityRef.addLiteral(Rex.hasEntityDetectionSource,
model.createPlainLiteral( source ));
