For some discussion of this point, see  http://www.ihmc.us/users/phayes/IKL/GUIDE/GUIDE.html#LogicForInt . In fact, a contextual logic does not work for ontologies in general. If the truth of an assertion depends on the context in which it is asserted, and if this context is not available when it is read, then it is USELESS. Or maybe worse than useless.
