SPARQL查詢使用RDF：身份證不返回任何結果

Question

我有一隻貓頭鷹的文件，我試圖運行查詢就可以了，但沒有得到任何結果請有人幫助我弄清楚並說明基本的查詢

public static void main(String[] args) { 
     String filename="H:/Samson_study/nodeTest/hRESTS-TC3/ontology/ApothecaryOntology.owl"; 
     Model model=ModelFactory.createDefaultModel(); 
     OntModel model1=ModelFactory.createOntologyModel(OntModelSpec.OWL_DL_MEM,model); 

     try 
     {   File file=new File(filename); 
      FileInputStream reader=new FileInputStream(file); 
      model.read(reader,null); 


      String query1=" PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> PREFIX my: <http://127.0.0.1/ontology/ApothecaryOntology.owl#> SELECT ?result WHERE { ?result rdf:ID my:HealthInsuranceNumber .}"; 

      Query query=QueryFactory.create(query1); 
      QueryExecution exe=QueryExecutionFactory.create(query, model1); 
      ResultSet RES=exe.execSelect(); 
      ResultSetFormatter.out(System.out, RES, query); 
     }catch(Exception e) 
     { 
      e.printStackTrace(); 
     } 
    } 

的本體是如下：

我沒有收到錯誤，但我不知道如何查詢貓頭鷹文件請幫助

Answer 1

您的查詢，添加了對可讀性換行，方法是：

PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> 
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> 
PREFIX my: <http://127.0.0.1/ontology/ApothecaryOntology.owl#> 

SELECT ?result WHERE { 
    ?result rdf:ID my:HealthInsuranceNumber . 
} 

當你看到RDF：在您的RDF/XML文件的ID，這不是真正的RDF三元組的屬性;相反，它用於指示RDF圖中資源的IRI是什麼。例如，片段：

<owl:Class rdf:ID="Costs"/> 

編碼的RDF三元：

...#Costs rdf:type owl:Class 

其中...是你的本體論的基礎IRI。這在RDF/XML規範的2.14 Abbreviating URIs: rdf:ID and xml:base部分中有描述。這個規範很長很複雜，就像RDF/XML一樣。不過，RDF/XML僅僅是RDF的序列化格式。 RDF本身非常簡單。只要有可能，我建議你不要直視RDF圖的RDF/XML序列化。相反，嘗試保存爲海龜。它更具人類可讀性，並且您將更好地瞭解圖中實際的三元組。例如，你在烏龜的本體是這樣的（我沒有複製整個東西）：

@prefix :  <http://127.0.0.1/ontology/ApothecaryOntology.owl#> . 
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . 
@prefix owl: <http://www.w3.org/2002/07/owl#> . 
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> . 

:Person a  owl:Class . 

:Patient a    owl:Class ; 
     rdfs:subClassOf :Person . 

:HospitalPhysician a owl:Class ; 
     rdfs:subClassOf :Physician . 

:TelephoneNumber a  owl:Class ; 
     rdfs:subClassOf :Number ; 
     owl:disjointWith :HealthInsuranceNumber . 

:Physician_hasID a owl:FunctionalProperty , owl:InverseFunctionalProperty , owl:ObjectProperty ; 
     rdfs:domain :Physician ; 
     rdfs:range :PhysicianID . 

:Disease_hasSymptom a owl:FunctionalProperty , owl:ObjectProperty ; 
     rdfs:domain :Disease ; 
     rdfs:range :Symptom . 

這幾乎與相應的SPARQL語法相同。

Answer 2

檢查本體和查詢都精確匹配的光圈。您正在搜索rdf:ID等於http://127.0.0.1/ontology/ApothecaryOntology.owl#HealthInsuranceNumber，但您的基本IRI沒有#字符，並且rdf:ID值也不是。這可能意味着文件中的值看起來像http://127.0.0.1/ontology/ApothecaryOntology.owlHealthInsuranceNumber而不是您所期望的。
