There has been some work before in partitioning Wikipedia articles into 
Instances and Concepts.
However this is a highly disputed topic. I would go with these being 
skos:Concepts :
http://en.wikipedia.org/wiki/Jaguar
http://en.wikipedia.org/wiki/Country
http://en.wikipedia.org/wiki/Leg

and these being instances:
http://en.wikipedia.org/wiki/Barack_obama
http://en.wikipedia.org/wiki/Empire_state_building

with these being problematic:
http://en.wikipedia.org/wiki/Luke_Skywalker
http://en.wikipedia.org/wiki/Roman_Empire

I would not like to discuss this in detail as it might lead to nothing. 
Please present a use case. Just to be able to use skos:*Match is not 
sufficient.  Maybe, we can make "usefullness" the main criteria.  
Besides, this might be also something, that you want to tackle in the 
Wikipedia Category system, directly ;)

So currently, we have owl:sameAs, skos:*Match and umbel:isLike. Any more?

I wouldn't disallow any of these.

Sebastian
