Prolog Ntriples Query Problem

Hello,


I am trying to query an Ntriples file (.nt) on Prolog using the following
code. It seems that I can load the data and consult it successfully.

But a problem occurs when I query the triples like rdf(X,Y,Z). It shows
some kind of strange error saying that " Correct to: "rdf_db:rdf(X,Y,Z)"? ".


PROLOG CODE:


:- use_module(library(semweb/rdf_ntriples)).

rdf_load('schema-full.nt').


Regards,
