Hi Rupert, thanks for your answers. I am working with XML files and want to transform them into RDF then use a NER engine to extract entities from those properties that have text like titles and abstracts (that we map to related DC properties). I was also searching a way to use another engine to interlink entites extracted from the transformation and from the NER engine above using a sparql endpoint that will add triples like <entity_1> <owl:sameAs> <entity_2> to the content item metadata. I was thinking to create enhancements every time a new resource is created by the transformation and a owl:sameAs relationship is found by an interlinking process. That will provide information about the document from which those triples have been extracted and the engines that made it like what happens when a plain text file is sent to a NLP engine.
