why does it have to be skilled?  there's an awful lot that people can 
do with good tools that will help make mappings without them even 
knowing it -- for example, if I say my pet is both a cyc:dog and a 
petshop:canine during some fill in the forms session (marking up 
pictures of my dog), som spider can come along later and bring that 
information along for other tools and or people to use.  I had some 
descriptions of a couple of scenarios of this a couple years back in 
the paper http://www.cs.umd.edu/~hendler/AgentWeb.html, and we've 
started exploring a number of tools in this space in my research lab
