In the experiments behind EXYGEN, several configurations generated executable SPARQL more than 97% of the time yet achieved zero correct execution results. The strongest configuration reached 97.8% executability and 41.9% relaxed exact match on execution results only after combining graph-derived metadata, explicit schema constraints, retrieved triples, and question-query examples. ...
