为什么不增加超时变量？ – Artemis

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

我认为它与偏移有关。它没有抵消工作吗？你能解释一下你想达到什么吗？在抵消之后你想要一个具有这些特质的人吗？ – Artemis

第1条 - 为清晰起见而编辑的查询，并附有一些语法更正。

SELECT DISTINCT        ?dbpedia_link 
               ?freebase_link 
       (   str(?abstract) AS ?abstract   ) 
       (    str(?alias) AS ?alias    ) 
       (   str(?birthDate) AS ?birthDate   ) 
       (   str(?birthName) AS ?birthName   ) 
       (  str(?birthPlace) AS ?birthPlace  ) 
       (    str(?label) AS ?label    ) 
       (  str(?occupation) AS ?occupation  ) 
       (   str(?residence) AS ?residence   ) 
       (   str(?spouse) AS ?spouse   ) 
       (   str(?education) AS ?education   ) 
       (   str(?networth) AS ?networth   ) 
       (   str(?salary) AS ?salary   ) 
       (  str(?wikiPageID) AS ?wikiPageID  ) 
       (str(?wikiPageRevisionID) AS ?wikiPageRevisionID) 
       ( str(?shortDescription) AS ?shortDescription ) 
    WHERE { 
        { ?dbpedia_link   rdf:type    dbpedia-owl:Person } 
      OPTIONAL { ?dbpedia_link dbpedia-owl:abstract   ?abstract   } 
      OPTIONAL { ?dbpedia_link dbpedia-owl:alias    ?alias    } 
      OPTIONAL { ?dbpedia_link  dbpprop:birthDate   ?birthDate   } 
      OPTIONAL { ?dbpedia_link  dbpprop:birthName   ?birthName   } 
      OPTIONAL { ?dbpedia_link  dbpprop:birthPlace   ?birthPlace   } 
      OPTIONAL { ?dbpedia_link   rdfs:label    ?label    } 
      OPTIONAL { ?dbpedia_link  dbpprop:occupation   ?occupation   } 
      OPTIONAL { ?dbpedia_link  dbpprop:residence   ?residence   } 
      OPTIONAL { ?dbpedia_link  dbpprop:spouse    ?spouse    } 
      OPTIONAL { ?dbpedia_link  dbpprop:education   ?education   } 
      OPTIONAL { ?dbpedia_link  dbpprop:networth   ?networth   } 
      OPTIONAL { ?dbpedia_link  dbpprop:salary    ?salary    } 
      OPTIONAL { ?dbpedia_link dbpedia-owl:wikiPageID   ?wikiPageID   } 
      OPTIONAL { ?dbpedia_link dbpedia-owl:wikiPageRevisionID ?wikiPageRevisionID } 
      OPTIONAL { ?dbpedia_link  dbpprop:shortDescription ?shortDescription } 
      OPTIONAL { ?dbpedia_link   owl:sameAs    ?freebase_link 
          FILTER regex(?freebase_link, "^http://rdf.freebase.com")  } 
     } 
    LIMIT 1 
OFFSET 225930

事情2 - 你有未定义的前缀在那里。 dbpedia-owl？ dbpprop？

随机的修修补补，并要求随机的人在网络上寻求帮助可能给你一些成果，但你很可能会得到更快，有关特定产品和工具更准确，更相关的答案被要求在专用于这些论坛产品和工具，例如，DBpedia discussion mailing list，Virtuoso Users mailing list等
