Claim 18:
19. A method for selecting a cohort for a clinical study, the method comprising:
receiving, by a processor of a computing device, a universal graph;
accessing, by the processor, an unstructured electronic health record for each patient in a population of patients;
for each patient in the population of patients, transforming, by the processor, based on the universal graph, the associated unstructured electronic health records of the patient into a patient graph, the patient graph representing a set of clinical concepts and corresponding semantic roles for the patient;
receiving, by the processor, a first set of inclusion and exclusion criteria;
transforming, by the processor, based on the universal graph, the first set of inclusion and exclusion criteria into a first target graph, the first target graph representing a first set of target clinical concepts for the clinical study;
receiving, by the processor, a second set of inclusion and exclusion criteria;
transforming, by the processor, based on the universal graph, the first set of inclusion and exclusion criteria and the second set of inclusion and exclusion criteria into a second target graph for the clinical study; and
for each patient in the population of patients, in response to alignment between the patient graph of the patient and the second target graph, appending, by the processor, the patient to a subpopulation of patients.
