I have looked briefly at the DBpedia ontology and it appears to leave a
great deal to be desired in terms of what an ontology is best suited for: to
carefully and precisely define the meanings of terms so that they can be
automatically reasoned with by a computer, to accomplish useful tasks. I
will be willing to spend some time to reorganize the ontology to make it
more logically coherent, if (1) there are any others who are interested in
making the ontology more sound and (2) if there is a process by which that
can be done without a very long drawn-out debate.
I think that the general notion of formalizing the content of the WikiPedia
a a great idea, but to be useful it has to be done carefully. It is very
easy, even for those with experience, to put logically inconsistent
assertions into an ontology, and even easier to put in elements that are so
underspecified that they are ambiguous to the point of being essentially
useless for automated reasoning. The OWL reasoner can catch some things,
but it is very limited, and unless a first-order reasoner is used one needs
to be exceedingly careful about how one defines the relations.
I am totally new to this list, and would appreciate pointers to previous
posts discussing such issues related to the ontology. A quick scan of
recent posts did not turn up anything relevant to this matter.
Perhaps those who have been particularly active in building the ontology
would be willing to discuss the matter by telephone? This could help
educate me and bring me up to date quickly on what has been done here.
Meanwhile, Merry Christmas and Happy Hanukkah and Happy New Year to the
members of this group.
