It's hard to answer your question, because it mushes together several
distinct questions.  Let me try to separate them --

Q1: How does one avoid the ambiguity between different senses of the
word "bank" in the innards of ontologies?  The answer would be
namespaces.  (By the way, the banks you sit on are only banks in
Italian; in English they are "benches," which comes from the Italian,
but conveniently changed spelling, thus eliminating the confusion.  To
compensate, the earthen walls of rivers are called "banks," so if we
have a web service selling tours of river margins, the confusion is

Q2: How does one deal with the ambiguity of words in HCI for web
services?  Good question, also asked by Charlie Abela.

Q3: Must we do without Owl mechanisms such as inheritance when we use
Owl-S?  The answer is No!  Owl-S is an _application_ of Owl, and
doesn't replace a hair on its pointy little head.

Q4: Is there a problem with multiple inheritance if an agent is both
a service _and_ an "economical entity"?  I don't know, but I don't see
why there would be a problem.

Does any of these alternative questions come close to what you
