Abstract

A question answering system includes a storage for storing question information together with first time information, a storage for storing answer information with respect to the question information together with solver information and second time information, and an evaluating part for evaluating a solver indicated by the solver information based on the first and second time information.

Claims

1. A question answering system comprising:

first storing means for storing question information together with first time information;

second storing means for storing answer information with respect to the question information together with solver information and second time information; and

evaluating means for evaluating a solver indicated by the solver information based on the first and second time information.

2. A question answering system comprising:

first registering means for registering question information;

transmitting means for transmitting to a questioner an answer provided by a solver with respect to the registered question information;

second registering means for registering an evaluation of the answer made by the questioner; and

evaluating means for evaluating the solver based on the registered evaluation made by the questioner.

3. A question answering system comprising:

storing means for storing questions and corresponding answers;

counting means for counting a number of times a reference is made to each of the stored answers; and

evaluating means for obtaining a sum total of the number of times the reference is made to the stored answers for each of solvers who provided the answers, and evaluating each of the solvers based on the sum total.

4. A question answering system comprising:

registering means for registering answers with respect to questions;

evaluating means for evaluating each of solvers who provided the answers based on a predetermined calculation formula; and

determining means for determining an incentive with respect to each of the solvers depending on evaluation results obtained by said evaluating means.

5. A computer-readable storage medium which stores a program for causing a computer to operate as a question answering system, said program comprising:

first storing means for causing the computer to store question information together with first time information;

second storing means for causing the computer to store answer information with respect to the question information together with solver information and second time information; and

evaluating means for causing the computer to evaluate a solver indicated by the solver information based on the first and second time information.

6. A computer-readable storage medium which stores a program for causing a computer to operate as a question answering system, said program comprising:

first registering means for causing the computer to register question information;

transmitting means for causing the computer to transmit to a questioner an answer provided by a solver with respect to the registered question information;

second registering means for causing the computer to register an evaluation of the answer made by the questioner; and

evaluating means for causing the computer to evaluate the solver based on the registered evaluation made by the questioner.

7. A computer-readable storage medium which stores a program for causing a computer to operate as a question answering system, said program comprising:

storing means for causing the computer to store questions and corresponding answers;

counting means for causing the computer to count a number of times a reference is made to each of the stored answers; and

evaluating means for causing the computer to obtain a sum total of the number of times the reference is made to the stored answers for each of solvers who provided the answers, and evaluate each of the solvers based on the sum total.

8. A computer-readable storage medium which stores a program for causing a computer to operate as a question answering system, said program comprising:

registering means for causing the computer to register answers with respect to questions;

evaluating means for causing the computer to evaluate each of solvers who provided the answers based on a predetermined calculation formula; and

determining means for causing the computer to determine an incentive with respect to each of the solvers depending on evaluation results obtained by said evaluating means.
