Of course, they are there, but I haven't found any of those four
all that exciting.
Something I do find more useful in the immediate term is to bring in
specialized heavyweight taxonomies & databases. For instance, ITIS,
Mesh, PubChem, ATCCS, etc. For instance, if you look at an entry
like this in wikipedia,
http://en.wikipedia.org/wiki/Ranitidine
you see that drugs (for instance) are really well connected to
high-quality identifiers and categories. It's not a difficult project
to bring those out and mesh them a little better with the DBpedia
ontology. Conversely, it doesn't make a sense to put a lot of effort
into classifying drugs or living species in much more detail because the
job is already done.
(Unless you're ~really~ into the details: I've done some work with
ITIS because it's logically consistent, but there isn't 100% agreement
between taxonomists about everything. I looked at about 20 cases where
Wikipedia and ITIS disagreed about some detail came to the conclusion
that Wikipedia had a more modern viewpoint about 80% of the time)
Another interesting directions is to clearly identify "genetic
categories" (Mallard Duck, Honda Civic) as related things and keep a
clear distinction between "members of a generic category" and the
"generic category" itself. For instance, it's true in some sense that
any Person is a Eukaryote, but that's not a true relationship between a
Person and Eukaryote in the Dbpedia ontology... However,
http://en.wikipedia.org/wiki/Human
ought to be a Eukaryote.
I'd really like to see the ultralightweight approach of the DBpedia
ontology extended to things that are less concrete, things like
"concepts", "inventions", "products", etc. There are quite a few
really great types in Freebase such as "toplevel domain" that are
concrete and easy to model that aren't currently available in DBPedia.
