Mechanisms are provided that generate a knowledge data structure for a medical condition. The mechanisms parse a natural language positional statement data structure representing a natural language positional statement corresponding to a medical condition, where the natural language positional statement specifies guidance information and patient attributes indicative of patients for which an action may be performed for the medical condition. The mechanisms extract the patient attributes and a grading value associated with the natural language positional statement. The mechanisms generate at least one weight value associated with each of the patient attributes based on the grading value. The mechanisms provide the knowledge data structure, based on the extracted one or more patient attributes and the at least one weight value in association with an identifier of the action and an identifier of the medical condition, to a cognitive system that performs a cognitive operation based on the knowledge data structure.

A method, in a data processing system comprising at least one processor and at least one memory, the at least one memory comprising instructions executed by the at least one processor to cause the at least one processor to generate a knowledge data structure for a medical condition, the method comprising: parsing, by the data processing system, a natural language positional statement data structure representing a natural language positional statement corresponding to a medical condition, and wherein the natural language positional statement specifies guidance information and one or more patient attributes indicative of patients for which an action may be performed for the medical condition; extracting, by the data processing system, the one or more patient attributes, and a grading value associated with the natural language positional statement, from the natural language positional statement data structure; generating, by the data processing system, at least one weight value associated with each of the patient attributes based on at least the grading value associated with the natural language positional statement; and providing, by the data processing system, the knowledge data structure for the medical condition, based on the extracted one or more patient attributes and the at least one weight value in association with an identifier of the action and an identifier of the medical condition, to a cognitive system that performs a cognitive operation based on the knowledge data structure. 2. The method of claim 1, further comprising: cross-correlating, by the data processing system, the extracted patient attributes with other instances of references to the patient attributes in a set of medical knowledge resources, wherein the at least one weight value is calculated based on statistical measures generated by the cross-correlation and the grading value. 3. The method of claim 2, wherein the statistical measures comprise, for each patient attribute, an inverse document frequency (IDF) statistical measure of instances of references to the patient attribute in association with the medical condition in the set of medical knowledge resources. 4. The method of claim 2, wherein the statistical measures identify patient attributes that are of relative greater importance than others in the evaluation of treatments for the medical condition. 5. The method of claim 2, wherein cross-correlating the extracted patient attributes further comprises, for each patient attribute: calculating a statistical measure that represents a relative importance of the patient attribute to treatment of the medical condition based on types of references to the patient attribute in the set of medical knowledge resources. 6. The method of claim 1, wherein the weight value corresponding to each patient attribute is modified based on a correlation of the patient attributes with patient attributes of patients in a patient cohort for the medical condition, wherein a patient cohort is a grouping of patients where each patient in the patient cohort has a same medical condition. 7. The method of claim 2, wherein weight values associated with patient attributes that occur more frequently in electronic medical records of patients in the patient cohort for the medical condition are given higher values than patient attributes that occur less frequently in electronic medical records of patients in the patient cohort. 8. The method of claim 1, wherein the grading value is a grading value corresponding to a grading policy established by an oversight organization that oversees treatment of the medical condition. 9. The method of claim 1, wherein the knowledge data structure comprises at least one insight data structure of a pluggable medical condition base cartridge corresponding to the medical condition. 10. The method of claim 9, further comprising: installing, in a cognitive medical system, the medical condition base cartridge as a resource for performing a cognitive operation, to thereby generate a configured cognitive medical system; processing, by the configured cognitive medical system, one or more electronic medical records of a patient based on the installed medical condition base cartridge to thereby execute the cognitive operation on the one or more electronic medical records; and outputting, by the configured cognitive medical system, an output of a result of the execution of the cognitive operation. 11. A computer program product comprising a computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to: parse a natural language positional statement data structure representing a natural language positional statement corresponding to a medical condition, and wherein the natural language positional statement specifies guidance information and one or more patient attributes indicative of patients for which an action may be performed for the medical condition; extract the one or more patient attributes, and a grading value associated with the natural language positional statement, from the natural language positional statement data structure; generate at least one weight value associated with each of the patient attributes based on at least the grading value associated with the natural language positional statement; and provide the knowledge data structure for the medical condition, based on the extracted one or more patient attributes and the at least one weight value in association with an identifier of the action and an identifier of the medical condition, to a cognitive system that performs a cognitive operation based on the knowledge data structure. 12. The computer program product of claim 11, wherein the computer readable program further causes the computing device to: cross-correlate the extracted patient attributes with other instances of references to the patient attributes in a set of medical knowledge resources, wherein the at least one weight value is calculated based on statistical measures generated by the cross-correlation and the grading value. 13. The computer program product of claim 12, wherein the statistical measures comprise, for each patient attribute, an inverse document frequency (IDF) statistical measure of instances of references to the patient attribute in association with the medical condition in the set of medical knowledge resources. 14. The computer program product of claim 12, wherein the statistical measures identify patient attributes that are of relative greater importance than others in the evaluation of treatments for the medical condition. 15. The computer program product of claim 12, wherein the computer readable program further causes the computing device to cross-correlate the extracted patient attributes at least by, for each patient attribute: calculating a statistical measure that represents a relative importance of the patient attribute to treatment of the medical condition based on types of references to the patient attribute in the set of medical knowledge resources. 16. The computer program product of claim 11, wherein the weight value corresponding to each patient attribute is modified based on a correlation of the patient attributes with patient attributes of patients in a patient cohort for the medical condition, wherein a patient cohort is a grouping of patients where each patient in the patient cohort has a same medical condition. 17. The computer program product of claim 12, wherein weight values associated with patient attributes that occur more frequently in electronic medical records of patients in the patient cohort for the medical condition are given higher values than patient attributes that occur less frequently in electronic medical records of patients in the patient cohort. 18.
