我在本体中定义的数据属性

在本体中，我定义了数据属性树。

See Protege Screenshot: Data Properties

要查询的目标个人

我的目标个体在猫头鹰中的定义如下：

<owl:NamedIndividual rdf:about="http://www.owl.de/ontology/i40component-01#I40Component_e41bdfaa-7163-46ed-8cb3-350fa226bbaf_I40WorkCell1_AASmanifest">
    <rdf:type rdf:resource="http://www.owl.de/ontology/i40component-01#Manifest"/>
    <decription rdf:datatype="http://www.w3.org/2001/XMLSchema#string">An example work cell.</decription>
    <ele rdf:datatype="http://www.w3.org/2001/XMLSchema#string">35.0</ele>
    <lat rdf:datatype="http://www.w3.org/2001/XMLSchema#string">52.518611</lat>
    <lon rdf:datatype="http://www.w3.org/2001/XMLSchema#string">13.376111</lon>
    <name rdf:datatype="http://www.w3.org/2001/XMLSchema#string">I40 Work Cell 1</name>
    <production_date rdf:datatype="http://www.w3.org/2001/XMLSchema#string">2012-12-31T23:57:00</production_date>
    <uuid rdf:datatype="http://www.w3.org/2001/XMLSchema#string">e41bdfaa-7163-46ed-8cb3-350fa226bbaf</uuid>
</owl:NamedIndividual>

在Protege中，它看起来像： See Protege Screenshot: Individual in Protege

目标结果

目标/目的是查询Protege或OWL代码段中显示的所有已定义数据属性。该查询的预期结果应为：

----------------------------------------------------------------------------------------------------------------------------------------------------------

----------------------------------------------------------------------------------------------------------------------------------------------------------

我当前的SPARQL查询和结果

我当前的测试方法如下所示。它构建并执行一个SPARQL查询。

@Test
public void showDataPropertiesOfWholeManifest() {
    SelectBuilder sb = new SelectBuilder() //Building a Query template
            .addPrefix("i40comp", owl.getI40NameSpace() + "#")
            .addPrefix("rdfs", "http://www.w3.org/2000/01/rdf-schema#")
            .addPrefix("xsd", "http://www.w3.org/2001/XMLSchema#")
            .addPrefix("owl", "http://www.w3.org/2002/07/owl#")
            .addPrefix("rdf", "http://www.w3.org/1999/02/22-rdf-syntax-ns#");

    //Define Variables      
    sb.addVar("?I40Component");
    sb.addVar("?dataProperty");
    sb.addVar("?datatypeValue");

    //Find Individuals for Type "Manifest"
    sb.addWhere("?I40Component", "rdf:type", URI.generateSparqlURI(I40VOC.Classes.AssetAdministrationShell.Manifest));

    //Find Individual with UUID "e41bdfaa-7163-46ed-8cb3-350fa226bbaf"
    sb.addWhere("?I40Component", "i40comp:uuid", "e41bdfaa-7163-46ed-8cb3-350fa226bbaf"); //Filter I40Component

    //Get all properties of this individual
    sb.addWhere("?dataProperty", "?", "owl:DatatypeProperty");

    // Results preparation
    sb.addWhere("?I40Component", "?dataProperty", "?datatypeValue");

    //Filters blanks and literals
    try {
        sb.addFilter("!isBlank(?datatypeValue)");
        sb.addFilter("isLiteral(?datatypeValue)");
    } catch (ParseException e) {
        e.printStackTrace();
    }

    //Build query and print result
    Query q = sb.build();
    executeSPARQLqueryAndPrintResult(q);
}

或再次作为查询字符串：

PREFIX  xsd:  <http://www.w3.org/2001/XMLSchema#>
PREFIX  i40comp: <http://www.owl.de/ontology/i40component-01#>
PREFIX  rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX  owl:  <http://www.w3.org/2002/07/owl#>
PREFIX  rdf:  <http://www.w3.org/1999/02/22-rdf-syntax-ns#>

SELECT  ?I40Component ?dataProperty ?datatypeValue
WHERE
  { ?I40Component
              rdf:type       i40comp:Manifest ;
              i40comp:uuid   "e41bdfaa-7163-46ed-8cb3-350fa226bbaf" .
    ?dataProperty
              ?              owl:DatatypeProperty .
    ?I40Component
              ?dataProperty  ?datatypeValue
    FILTER ( ! isBlank(?datatypeValue) )
    FILTER isLiteral(?datatypeValue)
  }

不幸的是结果不是我需要的结果。查看以下结果：

----------------------------------------------------------------------------------------------------------------------------------------------------------
| I40Component                                                                       | dataProperty             | datatypeValue                          |

----------------------------------------------------------------------------------------------------------------------------------------------------------

以某种方式，SPARQL查询转到“上层数据属性”，并选择它们作为结果，并打印实际子属性的值。喜欢：

| i40comp:I40Component_e41bdfaa-7163-46ed-8cb3-350fa226bbaf_I40WorkCell1_AASmanifest | i40comp:wpt_gps_location | "52.518611"                            |

通常应该是哪个：

| i40comp:I40Component_e41bdfaa-7163-46ed-8cb3-350fa226bbaf_I40WorkCell1_AASmanifest | i40comp:lat              | "52.518611"                            |

也许你们中的一个可以解释我为什么会发生这种情况，也可以通过改进查询以达到目标结果来支持我。

Answer 1

解决方案

所需的提示来自AKSW：

查询结果出了什么问题？我的意思是，这显然是由于推理。所以我的猜测-您没有显示模型的类型用过的-您正在使用推理模型。我对吗？你知道吗推理又是推理？我你只想要断言的数据最简单的情况是使用默认模型并将数据加载到此模型中一个– AKSW

问题是耶拿使用了推理模型（推理又称为推理）：

OntModel mONT = ModelFactory.createOntologyModel();

这类模型还提供干扰数据。

要仅获得我所针对的断言数据，最简单的方法是仅使用默认模型而不是本体模型（Model而不是OntModel）：

Model mONT = ModelFactory.createDefaultModel()

通过此更改，我只会得到断言的数据和目标结果：
