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].
