Abstract: A method for authoring clinical diagnosis data includes: parsing, on a processing device, clinical data regarding components and diagnoses of diseases, the components including at least one of signs, symptoms, or factors for generating structured clinical data; correlating, on the processing device, the structured clinical data based on at least one of the components; determining, on the processing device, clusters of the components that are related to the diseases; identifying, using principal component analysis on the processing device, one or more predictive components of the clusters of the components related to the diseases for generating a diagnosis predictive model; and generating, on the processing device, a disease model based on the diagnosis predictive model, the disease model being for diagnosing a patient in accordance with the identified one or more predictive components.
