Abstract

A computer-implemented method for creating question-answer pairs is provided. The computer-implemented method includes leveraging domain specific resources including, at least one or more of lexicons, glossaries, or knowledge bases for constructing templates for creating the question-answer pairs. The computer implemented method further includes leveraging user experiences of a plurality of users for constructing templates. The computer implemented method further includes eliminating erroneous question-answer pairs based on templates specifications of a heuristic process of the constructed templates.

First claim

What is claimed is:

1. A computer-implemented method, the computer-implemented method comprising:
retrieving question-answer pairs from a database;
constructing question-answer pair templates, wherein the constructing is based on leveraging domain specific resources and user experiences of a plurality of users; and
eliminating erroneous question-answer pairs from the retrieved question-answer pairs based on specifications of a heuristic process of the constructed templates, wherein the heuristic process is based on a term definition text operation that analyzes question-forming strings and answer-forming strings based on a plurality of glossaries and sentence formulations of the constructed templates.

2. The computer-implemented method of claim 1 , wherein the templates identify facts of natural language text.

3. The computer-implemented method of claim 1 , wherein the templates include a question forming text with paraphrases.

4. The computer-implemented method of claim 1 , wherein a corpus of text is utilized to generate the question-answer pairs.

5. A computer system comprising:
one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage devices, and program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:
program instructions to retrieve question-answer pairs from a database;
program instructions to construct question-answer pair templates, wherein the constructing is based on leveraging domain specific resources and user experiences of a plurality of users; and
program instructions to eliminate erroneous question-answer pairs from the retrieved question-answer pairs based on specifications of a heuristic process of the constructed templates, wherein the heuristic process is based on a term definition text operation that analyzes question-forming strings and answer-forming strings based on a plurality of glossaries and sentence formulations of the constructed templates.

6. The computer system of claim 5 , wherein the templates identify facts of natural language text.

7. The computer system of claim 5 , wherein the template is a question forming text with paraphrases.

8. The computer system of claim 5 , wherein a corpus of text is utilized to generate the question-answer pairs.

9. A computer program product comprising:
one or more computer-readable tangible storage devices and program instructions stored on at least one of the one or more storage devices, the program instructions comprising:
program instructions to retrieve question-answer pairs from a database;
program instructions to construct question-answer pair templates, wherein the constructing is based on leveraging domain specific resources and user experiences of a plurality of users; and
program instructions to eliminate erroneous question-answer pairs from the retrieved question-answer pairs based on specifications of a heuristic process of the constructed templates, wherein the heuristic process is based on a term definition text operation that analyzes question-forming strings and answer-forming strings based on a plurality of glossaries and sentence formulations of the constructed templates.

10. The computer program product of claim 9 , wherein the templates identify facts of natural language text.

11. The computer program product of claim 9 , wherein a corpus of text is utilized to generate the question-answer pairs.
