    SERVICE neptune-ml:inference {
        neptune-ml:config neptune-ml:modelType 'SUBJECT_PREDICTION' ;
                          neptune-ml:input ?input ;
                          neptune-ml:predicate <http://aws.amazon.com/neptune/csv2rdf/object_Property/rated> ;
                          neptune-ml:output ?output ;
