Hi Andrea
The triples are in following format in the file [3]
<http://dbpedia.org/resource/Category:World_War_II>_<http://www.w3.org/2004/02/skos/core#broader>_<http://dbpedia.org/resource/Category:Conflicts_in_1940>
I'm not sure how can I use these triples to identify leaf categories,
can you please explain bit more about it?
Thanks
