Hi Rafa, Are you sure the enhancements of this text do not contain other entities. The contexts(URIs) on which the LDPath program is executed are obtained as follows:
Iterator<Triple> it = sci.getMetadata().filter(null, Properties.ENHANCER_ENTITY_REFERENCE, null); In other words, the source of the URIs is the metadata of the ContentItem, could you please look into the enhancement graph of your ContentItem whether there exists any other Orange related entities?
