Hi,  (01)
As part of an ontology-based reference data demonstrator I'm working on, I
decided to go look what was out there for free, or at least under creative
commons. I downloaded the OpenCyc OWL file and loaded it into my OWL editor
(all 124MB of it!).  (02)
I seem to be finding lots of orphan classes there - i.e. ones that are
sitting right at the top of the sub-super hierarchy. When I go look in the
OWL file itself, these classes seem to be in the file twice - once with
their sub-super relationship and once without.  (03)
As the file is so big, I can't be sure of what the problem is - it may well
be my OWL Editor struggling with such a large file.  (04)
Has anyone else encountered this problem, and if so do you know if there is
a corrected version available ? The only way I can find for contacting
OpenCyc is through their SourceForge forum, but it doesn't appear to be that
active.  (05)
Cheers
