Filtering results of SPARQL queries
<p>I want to retrieve all 20th century italian novelists' name.
I've written this:</p>

<p><code>SELECT ?label
WHERE{
?novelist a yago:ItalianNovelists.
?novelist rdfs:label ?label.
FILTER (langMatches(lang(?label), "EN"))
}
ORDER BY ?label</code></p>

<p>How can i filter the results?</p>
