Nathan, pedants,


A rather general remark in reaction to your question.
In order to find ontologies and terms of ontologies (classes,
properties), you can use ontology search engines such as OntoSelect
[1], Watson [2], OntoSearch [3], OntoSearch2 [4] or more general
Semantic Web search engines such as Falcons [5], SWSE [6], Sindice [7]
or Swoogle [8].
One drawback of these systems is that they tend to put forward big
ontologies that are not necessarily popular and which may not be the
best to use for the Linked Data community.
DERI is also working on an ontology-term-search engine, but I'm not
sure the prototype we have is publicly available.

[1] OntoSelect: http://olp.dfki.de/ontoselect
[2] Watson: http://watson.kmi.open.ac.uk/
[3] OntoSearch: http://eprints.aktors.org/369/
[4] OntoSearch2: http://www.ontosearch.org/
[5] Falcons: http://iws.seu.edu.cn/services/falcons/objectsearch/index.jsp
[6] SWSE: http://swse.org/
[7] Sindice: http://sindice.com/
[8] Swoogle: http://swoogle.umbc.edu/

When it comes to finding ontologies, Watson is pretty good. When it
comes to finding concepts, Falcons is, AFAICT, better. For finding
instances, SWSE is good. For finding Semantic Web documents in
general, Sindice may be a good choice.
I'm wondering if this should be referenced on the Pedantic Web website.

AZ.
