从sparql结果中提取实际值

Question

我正在使用dotnetrdf编写sparql查询来获取保存在我的本体中的执行器的类型，id和解释属性。即时通讯使用以下选择查询。

      "PREFIX AP0: <http://www.semanticweb.org/faiza/ontologies/2014/10/ActuatorProvider#> " +
      "PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>" +
      "PREFIX owl: <http://www.w3.org/2002/07/owl#>" +
      "PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>" +
      "PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>" +
    "SELECT *"+ 
    "WHERE {"+
     "?Name rdf:type AP0:Actuating_Device."+
     "?Name AP0:ActuatorID ?id."+
     "?Name AP0:ActuatorExplain ?Explain."+
     "?Name AP0:AcuatorCode "txtActuatorID.Text"}"

使用此方法显示结果

 public void datadisplay1(IEnumerable<string> variables, SparqlResultSet srs)
        {
            dataGridView1.Columns.Clear();
            int vn = 0;
            foreach (string v in variables)
            {
                dataGridView1.Columns.Add(v, v); ;
                this.dataGridView1.Columns[vn].Width = 300;
                  vn++;
            }


            foreach (SparqlResult r in srs)
            {
                int i = 0;
                object[] items = new object[vn];

                foreach (string s in variables)
                {

                    items[i++] = r.Value(s);

                }
                dataGridView1.Rows.Add(items );
                            }

这是我的猫头鹰文件

我在c＃中使用gridview来显示结果。它以这种形式给我结果

SD01^^http://www.w3.org/2001/XMLSchema#anyURI

如何从结果中删除URI。

Answer 1

您还没有展示完整的示例，因此我们无法告诉您如何显示SPARQL结果，因此很难回答您的具体问题（因为您还没有说明一个！） 。但是我可以尝试提供一些一般性的指示。

您看到的数据是每列中出现的INode实例的完整形式，因此，如果您只想访问部分值，则需要做的第一件事就是获取实际节点。这可以通过以下几种方式完成：

//Assuming your result row is in a variable r

//With Named Indexing
INode value = r["var"];

//With Indexing
INode value = r[0];

//With method
INode value = r.Value("var");

选择最适合您的用例的一个，一旦您拥有该节点，我们就可以检查它是什么类型的节点并采取相应的行动：

String text;
switch (value.NodeType)
{
  case NodeType.Literal:
    // Cast to more specific ILiteralNode in order to extract just the text
    // excluding the data type or language specifier if present
    ILiteralNode lit = (ILiteralNode)value;
    text = lit.Value;    
    break;

  case NodeType.Uri:
    // Case to more specific IUriNode in order to extract final segment of URI
    IUriNode uri = (IUriNode)value;

    // Depending on the URI format this might be in the Fragment, 
    // the last Path Segment or just the URI
    text = !String.IsNullOrEmpty(uri.Uri.Fragment) ? uri.Uri.Fragment : (uri.Uri.Segments.Length > 0 ? uri.Uri.Segments[uri.Uri.Segments.Length - 1] : uri.Uri.ToString());
    break;

  default:
    // For anything else default to ToString()
    text = value.ToString();
}

// Now do what you want with the text

您可能需要将其封装在可重用的类/方法中，具体取决于您需要调用它的位置和方式。

请注意，如果您将其绑定到GUI应用程序中的某种控件，那么通常有一些方法可以自定义数据的呈现方式，同时保留实际数据。

Answer 2

我在查询中使用以下内容得到了答案

SELECT？ind（str（？Name）as？name）（str（？Explain）as？explain）（str（？id）as？actid）

WHERE {.....}.
