People regularly misinterpret medical documents currently by examining
them without the proper medical training. Adding superclasses etc or
deleting elements as they feel necessary is just formalising the
process where normal people interpret advice given by medically
trained people.

Even if hospitals perfect a DSS system based on RDF and/or OWL for
internal use, it is unlikely they would publish the resulting
documents for patients to consume. OWL is a very brittle and sensitive
language, and even minor additions to its "truth" statements could
make the consequences different.

Hopefully patients and doctors never rely on purely logic driven DSS
for their only source of medical information, as much as an ideal
semantic web would have that as a goal. Some common sense is always
necessary to at least filter the bad data out before giving it to a
computer for its rule-driven opinion.

Cheers,

Peter
