Abstract

In a crowd-sourced question answering system, the user is allowed to provide clarifying information to eliminate some of the most probable solutions or answers. This allows the user to find less common solutions to a query.

Claims

1. A computer-implemented method of retrieving information in response to an input query, performed by a computer with a processor, the method comprising:

receiving the input query;

searching a data store, with the processor, based on the input query, and identifying factors that augment information in the input query to further define a problem defined in the input query and that are associated with the input query;

searching the data store, with the processor, to identify a first set of proposed solutions to the problem defined by the input query;

identifying, with the processor, the first set of proposed solutions as solutions that are relevant to the input query and that are associated with at least some of the factors that are associated with the input query;

displaying, with a user interface component, the first set of proposed solutions along with the factors associated with the first set of proposed solutions, and a user interface element that receives clarifying information that clarifies the problem defined by the input query; and

displaying a second set of proposed solutions, along with factors associated with the second set of proposed solutions, based on the input query and the clarifying information.

2. The computer-implemented method of claim 1 wherein identifying the first set of proposed solutions comprises:

identifying the most likely set of proposed solutions given the input query and the factors associated with the input query.

3. The computer-implemented method of claim 2 wherein displaying the second set of proposed solutions comprises:

identifying the second set of proposed solutions as proposed solutions that are less likely that the first set of proposed solutions given the input query and the factors associated with the input query but that are more likely than the first set of proposed solutions given the input query, the factors associated with the input query and the clarifying information.

4. The computer-implemented method of claim 3 wherein displaying a user interface element that receives clarifying information comprises:

displaying the factors associated with the first set of proposed solutions as selectable items that can be selected or removed from consideration by the processor in identifying proposed solutions.

5. The computer-implemented method of claim 4 wherein displaying the factors as selectable items comprises:

displaying buttons along with each factor that, when actuated, indicate that the factor is either selected or removed.

6. The computer-implemented method of claim 4 wherein displaying the factors as selectable items comprises:

displaying the factors as directly selectable, and, when a factor is selected, automatically replacing the input query with the selected factor and repeating the steps of searching the data store to identify the first set of proposed solutions, identifying the first set of proposed solutions, and displaying the first set of proposed solutions using the selected factor instead of the input query.

7. The computer-implemented method of claim 1 wherein identifying factors that augment information in the input query comprises identifying a matching query, stored in the data store, that matches the input query, along with factors associated in the data store with the matching query.

8. The computer-implemented method of claim 1 wherein displaying a proposed solution comprises:

displaying a selectable approval input corresponding to each displayed proposed solution, the approval input being selectable to indicate user approval of the corresponding proposed solution.

9. The computer-implemented method of claim 8 and further comprising:

receiving user selection of an approval input indicating approval of the corresponding proposed solution; and

revising scores associated with the proposed solution corresponding to the selected approval input to reflect the user approval of the proposed solution.

10. The computer-implemented method of claim 1 and further comprising:

automatically generating associations between factors and proposed solutions based on the clarifying information.

11. The computer-implemented method of claim 1 and further comprising:

automatically generating associations between factors and stored queries based on the clarifying information.

12. The computer-implemented method of claim 1 and further comprising:

automatically generating associations among factors based on the clarifying information.

13. The computer-implemented method of claim 1 wherein each association has a corresponding weight that indicates a strength of the association, and further comprising:

adjusting the weights corresponding to the associations based on the clarifying information.

14. The method of claim 9 and further comprising:

issuing an incentive to an author of the proposed solution corresponding to the selected approval input.

15. A question response system, comprising:

a user interface component that receives an input query that defines a problem;

a data store that stores community-authored queries, solutions and factors, the factors providing additional information related to the queries and solutions;

a factor association component generating associations between the factors and both the queries and the solutions, and among the factors;

a community interface component receiving, and storing in the data store, the community authored queries, solutions and factors;

a search and ranking component that identifies a stored similar query as being similar to the input query, that identifies factors associated with the stored, similar query and that uses the stored, similar query and its associated factors to identify a first set of proposed solutions to the problem defined by the input query, the user interface component displaying the first set of proposed solutions and the associated factors and displaying a selectable element that receives a user input changing the factors to be used by the search and ranking component, the search and ranking component identifying a second set of proposed solutions based on the changed factors; and

a computer processor that is a functional component of the system and that is activated by the user interface component, the factor association component, the community interface component, and the search and ranking component to facilitate generating associations, receiving community authored solutions and factors, and identifying similar queries and factors and proposed solutions.

16. The system of claim 15 wherein the factor association component generates additional associations based on the user input changing the factors.

17. The system of claim 16 wherein the factor association component comprises:

an administrator component that receives manual input of associations; and

a machine learning component that automatically generates associations based on a plurality of different user inputs.

18. The system of claim 15 wherein the user interface component displays a solution selection input that receives a user selection of a proposed solution, and further comprising:

an incentives generator that generates incentives for community members that author proposed solutions that are selected.

19. A computer implemented method, comprising:

receiving an input query;

identifying a first set of proposed solutions, authored by a community of users, that are most likely to address the input query, based on the input query and a set of factors associated with the input query;

displaying the first set of proposed solutions and an indication of the set of factors that were considered in identifying the first set of proposed solutions;

displaying a user interface element that receives a user input changing the set of factors;

identifying a second set of proposed solutions based on the input query and a changed set of factors obtained based on the user input;

displaying the second set of proposed solutions and the changed set of factors considered in identifying the second set of proposed solutions;

receiving user approval of one of the second set of proposed solutions;

modifying associations among proposed solutions and factors based on the user approval; and

generating an incentive for a community member that authored the one proposed solution approved by the user.

20. The method of claim 19 wherein the factors are associated with the proposed solutions by weighted associations, and further comprising:

revising the weighted associations based on inputs from users and from the community.
