Abstract

Systems, methods, and computer program products to perform an operation comprising receiving a case, generating a set of candidate answers for the case, excluding a first candidate answer from the set of candidate answers upon determining that a first attribute in the case precludes returning the first candidate answer as a valid response to the case, and processing supporting evidence for the remaining candidate answers in the set of candidate answers.

Claims

1. A method, comprising:

receiving a case;

generating a set of candidate answers for the case;

excluding a first candidate answer from the set of candidate answers upon determining that a first attribute in the case precludes returning the first candidate answer as a valid response to the case; and

processing supporting evidence for the remaining candidate answers in the set of candidate answers.

2. The method of claim 1, wherein the set of candidate answers specifies candidate answers for which supporting evidence will be processed, wherein supporting evidence is not processed for the first candidate answer, wherein excluding the first candidate answer is based on a confidence score for the first candidate answer that is below a minimum confidence threshold.

3. The method of claim 1, wherein determining that the first attribute precludes returning the first candidate answer as a valid response to the case is based on at least one rule for processing the case.

4. The method of claim 1, wherein an output of a candidate answer scoring algorithm determines that the first attribute precludes returning the first candidate answer as a valid response to the case.

5. The method of claim 1, further comprising:

outputting, to a user presenting the case, an indication that supporting evidence for the candidate answer is not included as part of a response to the case at least in part due to the first attribute.

6. The method of claim 1, further comprising:

excluding a second candidate answer from the set of candidate answers upon determining that at least one of the first attribute and a second attribute preclude returning the second candidate answer as a valid response to the case.

7. The method of claim 1, further comprising:

storing an indication that the first attribute is relevant to returning a valid response to a class of cases including the received case.

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;

generating a set of candidate answers for the case;

excluding a first candidate answer from the set of candidate answers upon determining that a first attribute in the case precludes returning the first candidate answer as a valid response to the case; and

processing supporting evidence for the remaining candidate answers in the set of candidate answers.

9. The system of claim 8, wherein the set of candidate answers specifies candidate answers for which supporting evidence will be processed, wherein supporting evidence is not processed for the first candidate answer, wherein excluding the first candidate answer is based on a confidence score for the first candidate answer that is below a minimum confidence threshold.

10. The system of claim 8, wherein determining that the first attribute precludes returning the first candidate answer as a valid response to the case is based on at least one rule for processing the case.

11. The system of claim 8, wherein an output of a candidate answer scoring algorithm determines that the first attribute precludes returning the first candidate answer as a valid response to the case.

12. The system of claim 8, the operation further comprising:

outputting, to a user presenting the case, an indication that supporting evidence for the candidate answer is not included as part of a response to the case at least in part due to the first attribute.

13. The system of claim 8, the operation further comprising:

excluding a second candidate answer from the set of candidate answers upon determining that at least one of the first attribute and a second attribute preclude returning the second candidate answer as a valid response to the case.

14. The system of claim 8, the operation further comprising:

storing an indication that the first attribute is relevant to returning a valid response to a class of cases including the received case.

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;

receive a case;

generate a set of candidate answers for the case;

exclude a first candidate answer from the set of candidate answers upon determining that a first attribute in the case precludes returning the first candidate answer as a valid response to the case; and

process supporting evidence for the remaining candidate answers in the set of candidate answers.

16. The computer program product of claim 15, wherein the set of candidate answers specifies candidate answers for which supporting evidence will be processed, wherein supporting evidence is not processed for the first candidate answer, wherein excluding the first candidate answer is based on a confidence score for the first candidate answer that is below a minimum confidence threshold.

17. The computer program product of claim 15, wherein determining that the first attribute precludes returning the first candidate answer as a valid response to the case is based on at least one rule for processing the case.

18. The computer program product of claim 15, wherein an output of a candidate answer scoring algorithm determines that the first attribute precludes returning the first candidate answer as a valid response to the case.

19. The computer program product of claim 15, wherein the computer-readable program code is further executable to:

output, to a user presenting the case, an indication that supporting evidence for the candidate answer is not included as part of a response to the case at least in part due to the first attribute.

20. The computer program product of claim 15, wherein the computer-readable program code is further executable to:

exclude a second candidate answer from the set of candidate answers upon determining that at least one of the first attribute and a second attribute preclude returning the second candidate answer as a valid response to the case.
