我有这样的RDF数据：（更新，完整文件）

我得到这个RDF的来源是：http ://reach.suny.edu/display/Hajagos_Janos 当你在头像下的“回形针”按钮时，你可以下载这个文件。SPARQL 端点是： http: //link.informatics.stonybrook.edu/sparql/

我想查找姓氏为 的人的出版物"Hajagos"。从数据中，我们可以看到它在<rdfs:label> "Linked open drug data for pharmaceutical research and development". 但也有很多相同下的值<rdfs:label>。我怎么能查询到这个。我尝试了以下 SPARQL，但没有任何用处：

PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX foaf: <http://xmlns.com/foaf/0.1/>
PREFIX vivo: <http://vivoweb.org/ontology/core#>

SELECT ?publication
WHERE {
  ?person foaf:lastName "Hajagos" .
  ?person rdfs:label ?publication
}

通过这个查询我只能得到en-US，这也是属性的一个值<rdfs:label>。

如果您获取数据并将其转换为更易于阅读的格式（例如 Turtle），则可以更轻松地查看数据中的联系。具体来说，经过转换后，我们得到了我们关注的作者的如下描述：

<http://reach.suny.edu/individual/Hajagos_Janos>
        a                         reach:SUNY_REACH_Investigator , foaf:Person , foaf:Agent , owl:Thing ;
        rdfs:label                "Hajagos, Janos"@en-US ;
        bibo:suffixName           "Ph.D." ;
        j.0:networkId             "jhajagos" ;
        vitro-public:mainImage    <http://reach.suny.edu/individual/n1206> ;
        vivo:authorInAuthorship   <http://reach.suny.edu/individual/gHajagos_Janos_21575203> ;
        vivo:educationalTraining  <http://reach.suny.edu/individual/n20726> ;
        vivo:email                "risk.limits@gmail.com" ;
        vivo:faxNumber            "631-444-8873" ;
        vivo:hasMemberRole        <http://reach.suny.edu/individual/n2444> ;
        vivo:hasPresenterRole     <http://reach.suny.edu/individual/n6042> ;
        vivo:hasResearchArea      <http://link.informatics.stonybrook.edu/umls/CUI/C0010992> , <http://link.informatics.stonybrook.edu/umls/CUI/C1882937> , <http://link.informatics.stonybrook.edu/umls/CUI/C0025071> , <http://link.informatics.stonybrook.edu/umls/CUI/C0085567> , <http://link.informatics.stonybrook.edu/umls/CUI/C0034379> , <http://reach.suny.edu/individual/n5408> , <http://link.informatics.stonybrook.edu/umls/CUI/C0025088> ;
        vivo:middleName           "G" ;
        vivo:personInPosition     <http://reach.suny.edu/individual/n4507> , <http://reach.suny.edu/individual/n6907> ;
        vivo:phoneNumber          "631-444-1596" ;
        vivo:preferredTitle       "Senior Programmer/Analyst<br />" ;
        vivo:primaryEmail         "janos.hajagos@stonybrook.edu" ;
        foaf:firstName            "Janos"^^<http://www.w3.org/2001/XMLSchema#string> ;
        foaf:lastName             "Hajagos"^^<http://www.w3.org/2001/XMLSchema#string> .

与作者身份相关的内容并不多，但有谓词和宾语：

vivo:authorInAuthorship   <http://reach.suny.edu/individual/gHajagos_Janos_21575203> ;

如果我们跟随那个对象，我们会看到：

<http://reach.suny.edu/individual/gHajagos_Janos_21575203>
        a                               owl:Thing , vivo:Relationship , vivo:Authorship ;
        vivo:linkedAuthor               <http://reach.suny.edu/individual/Hajagos_Janos> ;
        vivo:linkedInformationResource  <http://reach.suny.edu/individual/a21575203> .

它可能是<http://reach.suny.edu/individual/a21575203>我们感兴趣的链接信息资源。没有很多信息，但有

<http://reach.suny.edu/individual/a21575203>
        rdfs:label  "Linked open drug data for pharmaceutical research and development." .

基于这种结构，我们可以编写一个查询来查找vivo:Authorships 和它们vivo:linkedAuthor的 s，以及rdfs:label任何vivo:linkedInformationResources 的 s。要专门查询"Hajagos"，您可以使用：

PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX foaf: <http://xmlns.com/foaf/0.1/>
PREFIX vivo: <http://vivoweb.org/ontology/core#>

SELECT ?label
WHERE {
  ?authorship vivo:linkedAuthor ?author ;
              vivo:linkedInformationResource ?resource .
  ?author foaf:lastName "Hajagos" .
  ?resource rdfs:label ?label .
}

要获得更一般的结果（并稍微清理一下查询），您可以使用：

prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>
prefix foaf: <http://xmlns.com/foaf/0.1/>
prefix vivo: <http://vivoweb.org/ontology/core#>

select ?lastName ?label where {
  ?authorship vivo:linkedAuthor [ foaf:lastName ?lastName ] ;
              vivo:linkedInformationResource [ rdfs:label ?label ] .
}

SPARQL 结果

它会用您的数据产生这样的结果；

$ sparql --data data2.n3 --query query.rq
-------------------------------------------------------------------------------------------------------------------------------
| lastName                                             | label                                                                |
===============================================================================================================================
| "Hajagos"^^<http://www.w3.org/2001/XMLSchema#string> | "Linked open drug data for pharmaceutical research and development." |
-------------------------------------------------------------------------------------------------------------------------------

在端点运行时会产生很多结果。也就是说，我在端点的结果中看不到 Hajagos 的任何结果。我不知道这是为什么（但在下一节中有一些注意事项）。

注意事项

经过一些实验，似乎有一些警告。例如，如果我们用 object 搜索三元组"Hajagos"，我们会得到与搜索 不同的三元组"Hajagos"^^xsd:string。例如，这个查询

select ?s ?p { ?s ?p "Hajagos" }

返回

s                                          p
http://reach.suny.edu/individual/Hajagos_J http://xmlns.com/foaf/0.1/lastName

但是这个查询

select ?s ?p { ?s ?p "Hajagos"^^xsd:string }

返回

s                                              p
http://reach.suny.edu/individual/Hajagos_Janos http://xmlns.com/foaf/0.1/lastName

请注意，个人是不同的！这不是一个伟大的事态。我们可以查询两者，但是

select ?s ?p { 
  { ?s ?p "Hajagos" } UNION { ?s ?p "Hajagos"^^xsd:string }
}

发现

s                                              p
http://reach.suny.edu/individual/Hajagos_J     http://xmlns.com/foaf/0.1/lastName
http://reach.suny.edu/individual/Hajagos_Janos http://xmlns.com/foaf/0.1/lastName
