The next step is to create an instance of QueryExecution, a class that represents a single execution of a query.

下一步是创建QueryExecution的实例，这个类表示查询的一个执行。

youdao

To obtain a QueryExecution, call QueryExecutionFactory.create (query, model), passing in the query to execute and the model to run it against.

要获得QueryExecution，请调用QueryExecutionFactory . create (query, model)，并传入要执行的query以及查询要处理的model。

youdao

There are several different execute methods on QueryExecution, each performing a different type of query (see the sidebar entitled "Other types of SPARQL queries" for more information).

QueryExecution上有几种不同的执行方法，每个方法执行一种不同类型的查询(请参阅标题为“其他类型的SPARQL查询”的侧栏，以获得更多信息)。
