Hi Azamat,

one thing I would like to be able to do is enter a search query similar to
the following:

"Kiwi a bird"

using the "a" to indicate "rdf:type" and to substitute for "bird" the
classes known to represent that concept. The search would then be made
with the substituted list of classes specifying the entity type.

e.g. umbel-sc:Bird, yago:BirdsOfNewZealand as shown by
http://lod.openlinksw.com/

Would http://www.semanticWWW.com be able to provide the list of classes
for the nominated concept.

P.S. Great service Hugh

Cheers,

Richard
