SPARQL提示在網上很難找到。使用下面的示例，您可以填充您的本體。這讓我感到有些孤單，我正在回答自己的問題。

取而代之的是使用pubmed sparql端點，我使用了項目gutenberg端點。首先，我使用Protegé創建了本體。這非常簡單直接。 Followinh是一個查詢卡夫卡和吐溫關於DBPedia和Project Gutenberg的作品'元數據的示例。

這兩個查詢將要填充你創建本體。然後你可以查詢你新創建的本體。

您是否想使用SPARQL一次執行兩個本體查詢？如果那就很容易做到。取兩個本體（.OWL文件）並使用SPARQL（jena-fuseki服務器）查詢它，並獲取兩個OWL文件的PREFIX。

您能否詳細說明這個問題？你想要在端點上的OWL文件或SPARQL查詢的例子嗎？

使用SPARQL服務，你可以這樣做以下：

CONSTRUCT { 
    <dbpedia-value1> a <your-class1> . 
    <dbpedia-value1> ?p1 ?o1 . 
    <pubmed-value2> a <your-class2> . #or perhaps also <your-class1> 
    <pubmed-value2> ?p2 ?o2 . 
} 
WHERE { 
    SERVICE <http://dbpedia.org/sparql> { 
     <dbpedia-value1> a <dbp-class1> . 
     <dbpedia-value1> ?p1 ?o1 . 
    } 
    SERVICE <http://pubmed.bio2rdf.org/sparql> { 
     <pubmed-value2> a <pubmed-class1> . 
     <pubmed-value2> ?p2 ?o2 . 
    } 
}

這將在每個端點的一類獲得一組實例，並將它們映射到你的本體。對端點的查詢可以是任意複雜的（SPARQL IN在這裏可能很有用），但是一般技術是查詢數據並使用CONSTRUCT將這些值映射到本體中的三元組，然後保存構造的三元組。 （或直接將數據插入到圖表中。）

您也可以使用此模式來映射源和本體之間的屬性。在這種情況下，指定特定屬性的WHERE子句

<pubmed-value2> <pubmed-prop1> ?prop1value .

在...然後變換他們在構造查詢：

<pubmed-value2> <your-prop1> ?prop1value .
