Claim 5:
6. A decision-support system for medical diagnosis to a user of a medical system, comprising:
a display;
a computer processor comprising an input/output receiving input data from a user interface, a computer processor and a question-answering system;
a database provided for storing 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,
a computer 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, said computer processor being configured for:
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 of symptoms on the display;
displaying a selector of said user interface on the display for selecting the presence or absence of at least one of at least one of the symptoms;
receiving, from said selector on the user interface, information on the presence or absence for at least one of the symptoms displayed in said ordered list of symptoms; and

repeating the above steps of feature vector and score computation and of ordered list generation, to display a re-ordered list of symptoms and 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.
