This puts me in mind of the Norway school of `empirical semantics'
(Arne Naess, et al). I don't know much about either empirical
semantics or experimental philosophy, but they look pretty similar.
Also I think Jeff Pelletier has done this sort of research, asking
people about their use of words and looking for patterns in their
responses.
