A System to measure symptom specificity accounting symptom prevalence in diseases

摘要

The present invention relates to a disease defined as symptoms, an information entropy generation unit that calculates information entropy on diseases including symptoms of a patient for all diseases stored in a database; A symptom frequency information generator for calculating symptom frequency information for each disease indicating the frequency at which the patient's symptoms are expressed for each disease including the patient's symptoms; And a symptom specificity calculation unit that calculates disease specificity of a specific symptom using the information entropy and symptom expression frequency information for each disease.
