I just ran some queries over Swoogle's collection of 850K
RDF documents collected from the web.  See [1] and [2] for
the 100 largest RDF documents and OWL documents,
respectively.  Document size was measured in terms of the
number of triples.  For this query, a document was
considered to be an OWL document if it used a namespace that
contained the string OWL.

The version of Swoogle you get by going to
http://swoogle.umbc.edu/ is swoogle 2.  Its database has
been trapped in amber since last summer, when it was
corrupted, preventing us from adding new data.  We put our
efforts into a reimplementation, Swoogle 3, which will be
released early next week.  The data reported here is from
Swoogle 3's database.
