Abstract

A method for providing context aware queries in a network may include receiving a question directed to a question answering service from an originating node, routing the question to one or more candidate nodes selected based at least in part on context information associated with the question, receiving an answer to the question from at least one of the candidate nodes, and providing the answer to the originating node based at least in part on result parameters associated with the originating node. An apparatus and computer program product corresponding to the method are also provided.

Claims

1. A method comprising:

receiving a question directed to a question answering service from an originating node;

routing the question to one or more candidate nodes selected based at least in part on context information associated with the question;

receiving an answer to the question from at least one of the candidate nodes; and

providing the answer to the originating node based at least in part on result parameters associated with the originating node.

2. The method of claim 1, wherein routing the question comprises routing the question without an indication of an identity of the originating node.

3. The method of claim 1, wherein providing the answer comprises providing the answer without an indication of an identity of the at least one of the candidate nodes providing the answer.

4. The method of claim 1, wherein providing the answer comprises providing the answer based at least in part on result parameters defining a set of nodes to which the question is routable and a response time by which the answer is to be provided.

5. The method of claim 1, further comprising storing the answer as a historical answer and determining whether to provide the historical answer in response to a future question.

6. The method of claim 1, further comprising providing flexible billing for providing the answer based at least in part on the result parameters.

7. The method of claim 1, further comprising enabling the originating node to select the result parameters based at least in part on a subscription level of the originating node with respect to the question answering service or on a per-question basis.

8. The method of claim 1, wherein routing the question comprises routing the question in response to determining the context information based at least in part on question domain or location of interest.

9. The method of claim 1, wherein routing the question comprises routing the question to candidates selected subsequent to candidate ranking based at least in part on a likelihood that each respective candidate is able to provide an accurate response to the question.

10. The method of claim 1, further comprising enabling direct communication between the originating node and a candidate node providing the answer in response to an indication of mutual assent from the originating node and the candidate node.

11. The method of claim 1, further comprising providing an indication to the originating node with respect to willingness of a candidate node providing the answer to accept follow-on questions.

12. A computer program product comprising at least one computer-readable storage medium having computer-executable program code instructions stored therein, the computer-executable program code instruction comprising:

program code instructions for receiving a question directed to a question answering service from an originating node;

program code instructions for routing the question to one or more candidate nodes selected based at least in part on context information associated with the question;

program code instructions for receiving an answer to the question from at least one of the candidate nodes; and

program code instructions for providing the answer to the originating node based at least in part on result parameters associated with the originating node.

13. The computer program product of claim 12, wherein the program code instructions for routing the question include instructions for routing the question without an indication of an identity of the originating node.

14. The computer program product of claim 12, wherein the program code instructions for providing the answer include instructions for providing the answer without an indication of an identity of the at least one of the candidate nodes providing the answer.

15. The computer program product of claim 12, wherein the program code instructions for providing the answer include instructions for providing the answer based at least in part on result parameters defining a set of nodes to which the question is routable and a response time by which the answer is to be provided.

16. The computer program product of claim 12, further comprising program code instructions for storing the answer as a historical answer and determining whether to provide the historical answer in response to a future question.

17. The computer program product of claim 12, further comprising program code instructions for providing flexible billing for providing the answer based at least in part on the result parameters.

18. The computer program product of claim 12, further comprising program code instructions for enabling the originating node to select the result parameters based at least in part on a subscription level of the originating node with respect to the question answering service or on a per-question basis.

19. The computer program product of claim 12, wherein the program code instructions for routing the question include instructions for routing the question in response to determining the context information based at least in part on question domain or location of interest.

20. The computer program product of claim 12, wherein the program code instructions for routing the question include instructions for routing the question to candidates selected subsequent to candidate ranking based at least in part on a likelihood that each respective candidate is able to provide an accurate response to the question.

21. The computer program product of claim 12, further comprising program code instructions for enabling direct communication between the originating node and a candidate node providing the answer in response to an indication of mutual assent from the originating node and the candidate node.

22. The computer program product of claim 12, further comprising program code instructions for providing an indication to the originating node with respect to willingness of a candidate node providing the answer to accept follow-on questions.

23. An apparatus comprising a processor configured to:

receive a question directed to a question answering service from an originating node;

route the question to one or more candidate nodes selected based at least in part on context information associated with the question;

receive an answer to the question from at least one of the candidate nodes; and

provide the answer to the originating node based at least in part on result parameters associated with the originating node.

24. The apparatus of claim 23, wherein the processor is configured to route the question by routing the question without an indication of an identity of the originating node.

25. The apparatus of claim 23, wherein the processor is configured to provide the answer by providing the answer without an indication of an identity of the at least one of the candidate nodes providing the answer.

26. The apparatus of claim 23, wherein the processor is configured to provide the answer by providing the answer based at least in part on result parameters defining a set of nodes to which the question is routable and a response time by which the answer is to be provided.

27. The apparatus of claim 23, wherein the processor is further configured to store the answer as a historical answer and determine whether to provide the historical answer in response to a future question.

28. The apparatus of claim 23, wherein the processor is further configured to provide flexible billing for providing the answer based at least in part on the result parameters.

29. The apparatus of claim 23, wherein the processor is further configured to enable the originating node to select the result parameters based at least in part on a subscription level of the originating node with respect to the question answering service or on a per-question basis.

30. The apparatus of claim 23, wherein the processor is further configured to route the question by routing the question in response to determining the context information based at least in part on question domain or location of interest.

31. The apparatus of claim 23, wherein the processor is configured to route the question by routing the question to candidates selected subsequent to candidate ranking based at least in part on a likelihood that each respective candidate is able to provide an accurate response to the question.
