Hi Masahide, If one ask me why? I would answer that it is become many of the wikipedia categories are classes and in such a case why not defining them as a Class, and not a category (that could be considered a class for some sense of that class)? Wikipedia category is a

Hi Richard, No. The Wikipedia category system is simply not appropriate as a class hierarchy. That's not a bug; it serves its purpose well, and the Wikipedia community likes it that way. It is essentially a tagging system, where tags themselves can be tagged. See [1] for an in-depth

Hi Richard I'm looking at: http://www.umbel.org/documentation.html I can't find umbel_class_hierarchy_v071.n3 there, and I also don't know if umbel_dbpedia_types_v071.nt is the same as the umbel_dbpedia_types.n3 available for download there (note the different formats). I think that
