The method also includes, applying text analytics to the unstructured text to identify one or more environmental risk factors associated with the geographic locations. The method also includes, computing a predictive risk model having, for each of the one or more environmental risk factors, a respective score indicative of a relevancy of the corresponding environmental risk factor to a health condition for the patient. The method also includes, outputting, in accordance with the one or more computed scores of the predictive risk model, information indicative of the relevancy of each of the environmental risk factors to the health condition of the patient.
