It depends on whether the system actually is a tree. When I made the app
above, the category system of the german Wikipedia was not a tree, but
it was easy enough to fix, and so only 10% of the articles end up being
in Kategorie:Sport or a subcategory. Kategorie:Wissenschaft (science) is
more of a problem, about 75% of articles can be found under that. To me,
the bigger problem is coming up with a list of these "broad categories",
if you want something more granular than people, places, events, things,
concepts, other, or whatever. If you had that, you could at least run a
couple of experiments (things to consider would be, for instance, how
deeply nested an article under "sports" is, categories of linking and
linked articles, how many articles are in or under some category). As an
example, Angela Merkel is in `German chemists`, but most of the linked
articles are in political categories, so a rule "person + politics =>
politician" if "politician" is a broad category in the system, that'd
be fairly easy to implement.
