Medical diagnosis can be modelled in terms of the classical notions of abduction, deduction and induction. Abduction is making a preliminary guess that allows to establish a set of plausible diagnostic hypotheses, followed by deduction for exploring their consequences and by induction for testing them with available patient data. Such a description of diagnostic reasoning at a knowledge level helps the construction of an expert systems by fashioning the adopted expert system building tool to reflect the structure of the problem rather than force the problem to the tool. To this aim reasoning strategies need to be represented abstractly, separately from medical facts and relations, so making the design more transparent and explainable. This paper describes how an already developed system, ANEMIA, able to provide a rather good diagnostic performance, has been re-implemented taking into account the above mentioned design criteria.

Abstract
Medical diagnosis can be modelled in terms of the classical notions of abduction, deduction and induction. Abduction is making a preliminary guess that allows to establish a set of plausible diagnostic hypotheses, followed by deduction for exploring their consequences and by induction for testing them with available patient data. Such a description of diagnostic reasoning at a knowledge level helps the construction of an expert systems by fashioning the adopted expert system building tool to reflect the structure of the problem rather than force the problem to the tool. To this aim reasoning strategies need to be represented abstractly, separately from medical facts and relations, so making the design more transparent and explainable. This paper describes how an already developed system, ANEMIA, able to provide a rather good diagnostic performance, has been re-implemented taking into account the above mentioned design criteria.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
