Hi Brad,<div>actually is there a schema of the graph?</div><div>you said &quot;directed&quot;, hence there should some hierarchy in it too.&#39;</div><div>I read there are 50K+ categories, maybe is there any list of &quot;directions&quot; aka &quot;links&quot; of how categories are connected?<br>

&gt; Hi,<br>
&gt; Whats the simplest way to extract complete and the latest Wikipedia Category<br>
&gt; Hierarchy?<br>
<br>
</div>Note that the &quot;category hierarchy&quot; isn&#39;t much of a hierarchy; it&#39;s a<br>
directed graph with cycles and no particular root.<br>
<br>
Your best bet is probably to download a database dump from<br>
<a href="http://dumps.wikimedia.org/enwiki/latest/" target="_blank">http://dumps.wikimedia.org/enwiki/latest/</a> and process it.<br>
