I think terms like "hard AI" and "soft AI" are potentially offensive
and imply a set of values (i.e. some set of problems being of more
value than others). Instead, I highly recommend that you use the
distinctions proposed by Jon Doyle in the AI Magazine (Spring 88),
in which he distinguishes between the following (note - the short
definitions are MINE, not Doyle's)

 o	COMPUTATIONAL COMPLEXITY ANALYSIS - i.e. the search for
	explanations based on comutational complexity

 o	ARTICULATING INTELLIGENCE - i.e. codifying command and expert
	knowledge.

 o	RATIONAL PSYCHOLOGY - i.e. the cognitive science that deals
	with trying to understand human thinking

 o	PSYCHOLOGICAL ENGINEERING - i.e. the development of new
	techniques for implementing human-like behaviors and
	capacities 

Note - using this demarcation it is easier to pin-point the different
areas in which a person is working.
