Hi, Whats the simplest way to extract complete and the latest Wikipedia Category Hierarchy?
Note that the "category hierarchy" isn't much of a hierarchy; it's a directed graph with cycles and no particular root.
Your best bet is probably to download a database dump from http://dumps.wikimedia.org/enwiki/latest/ and process it.
