I'm rather new to RDF, and have the basics nailed down, but I have a question about possible data sources (in addition to ontologies): is it possible to 'read' an (appropriately) Named Entity tag as an RDF subject-predicate-object(which would be the tagged text itself)... in its original context, that is to say, in its original text document?
I would not only like a query to pull a text excerpt as data itself (only linked to the original document), but allow an interface/query to include also the context in which it appeared (or: the text around it).
