Hi Helen --
I noticed your requirement ...
Now we are facing the new problem of
modelling "two or more" facts of a necessary condition for "order chest
X-ray" in the knowledge base. Furthermore, doctors will likely
tell you that no only they need to express "at least two or more", they
also want to express "fact A carries more weight or more indicative to
a diagnosis than fact B". If we were to model these "weighted
condition", we are opening a whole can of new worms, and I don't think
any SW reasoners now can do reasoning on this.
Our reasoner [1] for rules in open vocabulary English is not officially
blessed as a "SW reasoner", but it should easily support what you
need. Shared use is free .
Please take a look at the OWL, RDF and other examples at [2]. (You can run them in a browser at [1]).
If this is of potential interest, please expand a bit on the above use
case and provide some sample (invented) data. I'll be glad to
make a demo that you will be able to view, run and change by pointing a
browser to [1].
Thanks! -- Adrian
