Abstract

Multiple pieces of diagnostic information, which are necessary for disease diagnoses, and at least one piece of disease information, which represents a disease to be diagnosed in accordance with the diagnostic information, are stored. Link information is stored for each piece of disease information. The link information links the multiple pieces of the diagnostic information together in accordance with relationships among the pieces of the diagnostic information to be utilized at the time of a diagnosis of each disease and/or links the diagnostic information and the disease information together in accordance with relationships between the diagnostic information and the disease information. A probability of occurrence of a disease in accordance with the link information is stored previously. The probability of occurrence of each disease associated with inputted diagnostic information is acquired in accordance with the link information.
