Systems, methods, and computer program products to perform an operation comprising receiving a case from a user, determining a level of sophistication of the user, determining a level of sophistication associated with each of a plurality of items of supporting evidence in a corpus of information, selecting a subset of the plurality of items of supporting evidence based on the determined levels of sophistication, and returning the selected subset to the user as part of a response to the case.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method, comprising: receiving a case from a user; determining a level of sophistication of the user; determining a level of sophistication associated with each of a plurality of items of supporting evidence in a corpus of information used to process the case; selecting a subset of the plurality of items of supporting evidence based on the determined levels of sophistication; and returning the selected subset to the user as part of a response to the case. 2. The method of claim 1, further comprising: assigning a level of sophistication to each item of supporting evidence in the corpus based on at least one of: (i) a concept, subject, or topic of one or more passages in the document and (ii) unstructured text passages in the document. 3. The method of claim 1, wherein the level of sophistication of the user is based on at least one of: (i) a profile of the user, (ii) a default level of sophistication, and (iii) a level of sophistication of an input provided by the user. 4. The method of claim 1, wherein the subset includes items of supporting evidence having a determined level of sophistication matching the level of sophistication of the user. 5. The method of claim 1, wherein the level of sophistication of the user is further based on a role of the user. 6. The method of claim 1, wherein a first item of supporting evidence is not selected as part of the subset, the method further comprising: modifying at least one term in the first item of supporting evidence based on the level of sophistication of the user; and returning the modified first item of supporting evidence to the user as part of the response to the case. 7. The method of claim 1, further comprising: receiving a request from the user to view items of supporting evidence having a second level of sophistication, different than the level of sophistication of the user; and responsive to the request, returning at least one item of supporting evidence having the second level of sophistication to the user. 8. A system, comprising: one or more computer processors; and a memory containing a program, which when executed by the one or more computer processors, performs an operation comprising: receiving a case from a user; determining a level of sophistication of the user; determining a level of sophistication associated with each of a plurality of items of supporting evidence in a corpus of information used to process the case; selecting a subset of the plurality of items of supporting evidence based on the determined levels of sophistication; and returning the selected subset to the user as part of a response to the case. 9. The system of claim 8, the operation further comprising: assigning a level of sophistication to each item of supporting evidence in the corpus based on at least one of: (i) a concept, subject, or topic of one or more passages in the document and (ii) unstructured text passages in the document. 10. The system of claim 8, wherein the level of sophistication of the user is based on at least one of: (i) a profile of the user, (ii) a default level of sophistication, and (iii) a level of sophistication of an input provided by the user. 11. The system of claim 8, wherein the subset includes items of supporting evidence having a determined level of sophistication matching the level of sophistication of the user. 12. The system of claim 8, wherein the level of sophistication of the user is further based on a role of the user. 13. The system of claim 8, wherein a first item of supporting evidence is not selected as part of the subset, the operation further comprising: modifying at least one term in the first item of supporting evidence based on the level of sophistication of the user; and returning the modified first item of supporting evidence to the user as part of the response to the case. 14. The system of claim 8, the operation further comprising: receiving a request from the user to view items of supporting evidence having a second level of sophistication, different than the level of sophistication of the user; and responsive to the request, returning at least one item of supporting evidence having the second level of sophistication to the user. 15. A computer program product, comprising: a computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code executable by one or more computer processors to: receiving a case from a user; determining a level of sophistication of the user; determining a level of sophistication associated with each of a plurality of items of supporting evidence in a corpus of information used to process the case; selecting a subset of the plurality of items of supporting evidence based on the determined levels of sophistication; and returning the selected subset to the user as part of a response to the case. 16. The computer program product of claim 15, wherein the computer-readable program code is further executable to: assign a level of sophistication to each item of supporting evidence in the corpus based on at least one of: (i) a concept, subject, or topic of one or more passages in the document and (ii) unstructured text passages in the document. 17. The computer program product of claim 15, wherein the level of sophistication of the user is based on at least one of: (i) a profile of the user, (ii) a default level of sophistication, and (iii) a level of sophistication of an input provided by the user. 18. The computer program product of claim 15, wherein the subset includes a first item of supporting evidence, wherein the level of sophistication of the first item of supporting evidence matches the level of sophistication of the user, wherein the subset does not include a second item of supporting evidence, wherein the level of sophistication of the second item of supporting evidence does not match the level of sophistication of the user. 19. The computer program product of claim 15, wherein the level of sophistication of the user is further based on a role of the user. 20. The computer program product of claim 15, wherein a first item of supporting evidence is not selected as part of the subset, wherein the computer-readable program code is further executable to: modify at least one term in the first item of supporting evidence based on the level of sophistication of the user; and return the modified first item of supporting evidence to the user as part of the response to the case.
