IBM's Watson Does Diagnoses

Another piece about uses for the IBM Watson Computer.  Once again, patient diagnosis was an early application for artificial intelligence.  In particular pulmonary diagnosis was used as an early example.  Such systems can be seen as advisers to physician.   It makes sense, there is gathered personal data and a large library of patterns that resulted in specific diagnoses.  It is straightforward to find specific matches and attribute to each a level of credibility.   Could work where there are large quantities of complex data to be matched.
