I wish to restrict this URI Burner query to WordNet named graph only. Is the SPARQL syntax correct (it was generated by FCT)? If the syntax is correct, why are there items in the result set that do not logically belong to WordNet named graph? This FCT article states:
graph="graph_iri"installed default is to search in all graphs, but system defaults may override this
Is this behavior implemented at the SPARQL processor or at the FCT service endpoint? Also, is it the case that Virtuoso’s system default is overriding the graph set in the SPARQL, so that
input:default-graph-uri has no effect?
