爲什麼不增加超時變量？ – Artemis

@Artemis我做到了。我將** MaxQueryExecutionTime **增加到** 600000 **。依然不成功。 – iNikkz

我認爲它與偏移有關。它沒有抵消工作嗎？你能解釋一下你想達到什麼嗎？在抵消之後你想要一個具有這些特質的人嗎？ – Artemis

隨機的修修補補，並要求隨機的人在網絡上尋求幫助可能給你一些成果，但你很可能會得到更快，有關特定產品和工具更準確，更相關的答案被要求在專用於這些論壇產品和工具，例如，DBpedia discussion mailing list，Virtuoso Users mailing list等
