Hello everybody, i'm having a problem with the entityhubLinking engine.
I refactored my vocabulary so that the type is no longer specified by the
"rdf:type" predicate but by the "edfAcronyme:type", then configured the
"type field" parameter of the engine to the full URI of "edfAcronyme". But
in the rdf answer, there is no entity-type field. Actually, some
EntityAnnotations have en entity-type and some others don't.
Here is an excerpt of the rdf describing my refactored entity (curling the
managed site where it is stored):
<rdf:RDF
*xmlns:j.1="http://www.edf.fr/EdfAcronyme.owl#"*>
<rdf:Description rdf:about="http://www.edf.fr/EdfAcronyme.owl#EMI";>
*<j.1:type rdf:resource="http://www.edf.fr/EdfAcronyme.owl#Acronyme"/>*
</rdf:Description>
</rdf:RDF>
here is a piece of the text used to enhance:
"Monsieur Machin Groupe EMI: cellule performance EDF"
here is an excerpt of the rdf i get as the output - EntityAnnotation with
"entity-type":
<rdf:Description
rdf:about="urn:enhancement-1f443226-3f8b-aee9-ab31-6ca9a34dbaae">

</rdf:Description>
and now in the same result, EntityAnnotation without "entity-type",
for the same entity:
<rdf:Description
rdf:about="urn:enhancement-52cdf80e-64ed-9f1c-c4bb-6a2d222f732d">

Just for your information, the engine does spot another entity, "EDF", but
no EntityAnnotation with an "entity-type" field. Here it is :
<rdf:Description
rdf:about="urn:enhancement-8c54a60d-9854-f1bf-476d-07402c6dd90b">
<j.4:extracted-from

Here is part of the config of my engine :
enhancer.engines.linking.labelField="rdfs:label"
enhancer.engines.linking.typeField="http://www.edf.fr/EdfAcronyme.owl#type";
stanbol.enhancer.engine.name="EDFAcronymeMSLinking"
And now the config of the chain:
stanbol.enhancer.chain.weighted.chain=["langdetect","opennlp-sentence","opennlp-token","opennlp-pos","EDFAcronymeMSLinking"]
just to be sure i don't reference the wrong linking engine
Hope that helps you, either finds where i made a mistake, or a
potential bug in the engine.
Best Regards, Joseph
