DBpedia所有编程语言详细信息都需要SPARQL查询帮助

Question

这是我正在运行的查询，用于获取所有编程语言的这些详细信息。每种编程语言都会影响其他语言或受其他语言影响。因此，可能有许多语言受其影响或受其影响。现在，概率在打印时将其所有值分别打印在行中。您可以查看图片。我希望所有其影响或影响力的编程语言都在同一行中。查询在下面。

SELECT ?pl ?abstract ?influenced ?influencedBy
    WHERE { 
        ?pl dbo:abstract ?abstract .
            ?pl dbo:influenced ?influenced .
            ?pl dbo:influencedBy ?influencedBy .
            ?pl rdf:type dbo:ProgrammingLanguage .
            FILTER (LANG(?abstract) = 'en') .
          }

我的结果的屏幕截图

您会看到此语言有两个影响力dBy值，并且将它们打印在单独的行中。

就像@AKSW所说的，类似-

SELECT                                                      ?pl 
                                                            ?abstract
       ( group_concat ( ?_influenced; separator="; " )   AS ?influenced )
       ( group_concat ( ?_influencedBy; separator="; " ) AS ?influencedBy ) 
WHERE
  { ?pl  dbo:abstract      ?abstract . 
    ?pl  dbo:influenced    ?_influenced . 
    ?pl  dbo:influencedBy  ?_influencedBy . 
    ?pl  rdf:type          dbo:ProgrammingLanguage . 
    FILTER ( LANG ( ?abstract ) = 'en' ) . 
  } 
GROUP BY ?pl ?abstract

编辑以添加

要获取 ?pl_label （我猜是 ?_influenced_label 和 ?_influencedBy_label ）您现在说自己想要，您将需要（和/或想要）稍微调整一下内容...

SELECT                                                            ?pl 
                                                                  ?pl_label
       ( group_concat ( DISTINCT ?_influenced_label; separator="; " )   AS ?influenced )
       ( group_concat ( DISTINCT ?_influencedBy_label; separator="; " ) AS ?influencedBy ) 
                                                                  ?abstract
WHERE
  { ?pl             rdf:type          dbo:ProgrammingLanguage .
    ?pl             dbo:abstract      ?abstract . 
                    FILTER ( LANG ( ?abstract ) = 'en' ) 
    ?pl             rdfs:label         ?pl_label
                    FILTER ( LANG ( ?pl_label ) = 'en' ) .
    ?pl             dbo:influenced    ?_influenced . 
    ?_influenced    rdfs:label         ?_influenced_label
                    FILTER ( LANG ( ?_influenced_label ) = 'en' ) .
    ?pl             dbo:influencedBy  ?_influencedBy . 
    ?_influencedBy  rdfs:label         ?_influencedBy_label
                    FILTER ( LANG ( ?_influencedBy_label ) = 'en' ) .
          } 
GROUP BY ?pl ?pl_label ?abstract
