In other words, do we have methods to ensure that the elements (subject, object, predicates) of an RDF trillion store are of the quality to produce meaningful results in such an automated process of building graphs? Until that is done for specific area of our research, all these advances are hypothetical

Of course.

Please look at the analytics oriented examples for which I posted URLs. 
I purposely added a Uniprot citations link which is basically showing 
analytics scoped to statements in the DBMS.
