The Cyc Foundation now has a nice Concept Browser
http://www.cycfoundation.org/concepts
which lets you search for concepts in their huge KB.

Many concepts have links to Wikipedia articles.

You can also download the W3C standard
OWL language description of concept Name
http://www.cycfoundation.org/concepts/Name

my Knowledge Explorer (mKE) includes a command
cycexport Name
which downloads the OWL file, and translates it into
my Knowledge Representation language (mKR),
which is the user interface language for mKE.
