No, we never made the assertion that the bridge axiom creation was
entirely automatic.  We stated that with some axioms, the use of OWL with
inferencing algorithms can maintain the logical consistency, and answer
cross ontology queries (which was the original question).  I think Jim &
Bijan did a good job discussing the issues.  We do have tools that allow
some use of algorithms that do indeed suggest bridging axioms and generate
the appropriate OWL, but due to the different nature of these algorithms
(probabilistic among other techniques) as opposed to OWL-DL (deductive
logic), we advise some person-in-the loop work to ensure continuity. 
Again, once checked, cross ontology reasoning and querying works fine.  In
addition, the precision of these algorithms is greatly increased if
constrained within domains (i.e, not trying to compare a bookselling
webservice with a type of cancer, but only against other e-commerce
services)
