我是语义网络主题的新手,我创建了一个本体,我需要开发一个网站,该网站可以读取本体并从 OWL 文件中提取信息并将其显示在网站上我对我需要哪个库进行了一些研究使用,所以我发现最好的库中的 RDFdotnet 我需要用它来读取 owl 文件,我还找到了一个代码,但我需要有人解释或帮助我使用这个代码来读取我的 owl 文件。我想使用下拉列表和按钮请任何建议???
这是代码
//Define your Graph here - it may be better to use a QueryableGraph if you plan
//on making lots of Queries against this Graph as that is marginally more performant
IGraph g = new Graph();
//Load some data into your Graph using the LoadFromFile() extension method
g.LoadFromFile("myfile.rdf");
//Use the extension method ExecuteQuery() to make the query against the Graph
try
{
Object results = g.ExecuteQuery("SELECT * WHERE { ?s a ?type }");
if (results is SparqlResultSet)
{
//SELECT/ASK queries give a SparqlResultSet
SparqlResultSet rset = (SparqlResultSet)results;
foreach (SparqlResult r in rset)
{
//Do whatever you want with each Result
}
}
else if (results is IGraph)
{
//CONSTRUCT/DESCRIBE queries give a IGraph
IGraph resGraph = (IGraph)results;
foreach (Triple t in resGraph.Triples)
{
//Do whatever you want with each Triple
}
}
else
{
//If you don't get a SparqlResutlSet or IGraph something went wrong
//but didn't throw an exception so you should handle it here
Console.WriteLine("ERROR");
}
}
catch (RdfQueryException queryEx)
{
//There was an error executing the query so handle it here
Console.WriteLine(queryEx.Message);
}
