Claim 8:
9. A computer program product, stored on a non-volatile computer-readable data-storage medium, implemented in a decision-support system for autonomous medical diagnosis to a user of a medical system, said system comprising a display and a processor having a computer readable medium, said computer processor comprising an input/output receiving input data from a user interface, and a question-answering system; said computer program product comprising computer-executable instructions comprising:
providing a list of diseases and for each disease a list of symptoms associated with their prevalence in said disease, each symptom being mapped to an ontology database comprising codes, each code describing a symptom and having descendants corresponding to a more precise description of said symptom and ascendants corresponding to a less precise description of said symptom;
providing a state space (S) representing the user's current state of knowledge of said patient's condition with regard to each of said symptoms;
computing a feature vector (Π) representing an interest to check a particular symptom given the current state space (S);
computing, from said computed feature vector (Π), a score of interest to check a particular symptom;
generating an ordered list of symptoms to be checked by said user, based on decreasing score values;
displaying the ordered list on the display;
entering, by said user interface, information on the presence or absence for each symptom displayed in said ordered list of symptoms;
repeating the above steps of feature vector and score computation and of ordered list generation, to display a re-ordered list of symptoms based on the score values on said display;
displaying, based on and together with the re-ordered list the symptoms, a list of probable diagnosis with a probability diagnosis with each possible diagnosis on the display; and
changing, on the display, the list of probable diagnosis when the re-ordered list is changed.
