Dear all,

I'm trying to derive a tree of categories from DBPedia but as I get so
many top categories I have taken a deeper look into the data and
compared it with the Wikipedia counterpart.

It seems that there are many missing broader links among categories,
at least from what there is in Wikipedia.

For instance, compare:
http://dbpedia.org/resource/Category:1910s_births and
http://en.wikipedia.org/wiki/Category:1910s_births

In DBPedia, there is just a broader link from
http://dbpedia.org/resource/Category:Births_of_the_last_123_years and
no outgoing broader or narrower link.
In Wikipedia, there are 10 subcategories (from 1910 births to 1919
births) and two supercategories (1910s and 20th-century births).

Has someone experimented similar issues? Is there another available
dump of the Wikipedia categories using SKOS?

Any help appreciated,

Best,

Roberto García
