Expert Systems are a branch of Artificial Intelligence. These systems try to capture knowledge of Experts via set of rules. Most of the rules are stated in natural language. But they need to be interpreted by rule engine therefore they are statements in the form of classic if-then-else.
IF THEN ELSE
This specific expert system will hold substances and patients. Every rule give an advice according to patient's attributes , which is stored in database.
IF (PatientWeight < 50 AND PatientSex = Male AND DaysInTreatment = 0) THEN SUBSTANCE_X = 10 IF (PatientWeight < 50 AND PatientSex = Male AND DaysInTreatment > 0) THEN SUBSTANCE_X = 20 + DaysInTreatment *5
I have never designed such a system. Can you give me some starting pointers to read? Or Any advice?
