Abstract

Embodiments of the present invention relate to an approach for reusing information/knowledge. Specifically, embodiments of the present invention provide an approach for retrieving previously stored data to satisfy queries (e.g., jobs/tickets) for solutions to problems while maintaining privacy/security of the data as well as ensuring the quality of the results. In a typical embodiment, a query for a solution to a problem is received and details are extracted therefrom. Using the details, a search is performed on a set of data stored in at least one computer storage device. Based on the search, a set of results will be generated and classified into a set of categories. In any event, the quality of each of the set of results will be assessed based on the usefulness of the set of results.

Claims

1. A method for reusing information, comprising:

receiving, by at least one computing device, a query for a solution to a problem;

extracting, by the at least one computing device, details from the query;

performing, by the at least one computing device, a search on a set of data stored in at least one computer storage device using the details;

generating, by the at least one computing device, a set of results based on the search;

determining at least one domain of the set of results;

classifying the set of results of the at least one domain into a set of domain-specific categories based on keywords, wherein a result of the set of results may belong to more than one domain-specific category;

assessing, by the at least one computing device, a quality of each of the set of results based on;

correspondence with information in a problem statement part of the query,

structural and content level features derived from text of a resolution part of the query, and

user ratings;

generating a model classifying a quality of each sentence in the set of results;

generating a score based on the model;

ranking, by the at least one computing device, the set of results within the domain-specific categories based on the score; and

displaying the set of results on a display device;

wherein the at least one computing device comprises a processor and a memory.

2. The computer-implemented method of claim 1, the details extracted from the query comprising at least one of the following:

a program name, a module name, or a keyword from the query.

3. The method of claim 1, wherein a service solution provider provides a computer infrastructure comprising the at least one computing device that performs the method for one or more consumers.

4. The computer-implemented method of claim 1, further comprising sanitizing the set of results prior to the classifying, the sanitizing comprising removing private details from the set of results.

5. A system for reusing information, comprising:

a memory medium comprising instructions;

a bus coupled to the memory medium; and

a processor coupled to the bus that when executing the instructions causes the system to;

receive a query for a solution to a problem;

extract details from the query;

perform a search on a set of data stored in at least one computer storage device using the details;

generate a set of results based on the search;

determine at least one domain of the set of results;

classify the set of results of the at least one domain into a set of domain-specific categories based on keywords, wherein a result of the set of results may belong to more than one domain-specific category;

assess a quality of each of the set of results based on;

correspondence with information in a problem statement part of the query,

structural and content level features derived from text of a resolution part of the query; and

user ratings;

generate a model classifying a quality of each sentence in the set of results;

generate a score based on the model;

rank the set of results within the domain-specific categories based on the score; and

display the set of results on a display device.

6. The system of claim 5, the details extracted from the query comprising at least one of the following:

a program name, a module name, or a keyword from the query.

7. The system of claim 5, the memory medium further comprising instructions for causing the system to sanitize the set of results prior to the classification.

8. The system of claim 7, the memory medium further comprising instructions for causing the system to remove private details from the set of results.

9. A computer program product for reusing information, the computer program product comprising a computer readable storage media, and program instructions stored on the computer readable storage media, which when executed by a computer, cause the computer to:

receive a query for a solution to a problem;

extract details from the query;

perform a search on a set of data stored in at least one computer storage device using the details;

generate a set of results based on the search;

determine at least one domain of the set of results;

classify the set of results of the at least one domain into a set of domain-specific categories based on keywords, wherein a result of the set of results may belong to more than one domain-specific category;

assess a quality of each of the set of results based on;

correspondence with information in a problem statement part of the query,

structural and content level features derived from text of a resolution part of the query, and

user ratings;

generate a model classifying a quality of each sentence in the set of results;

generate a score based on the model;

rank the set of results within the domain-specific categories based on the score; and

display the set of results on a display device;

wherein the computer comprises a processor and memory.

10. The computer program product of claim 9, the computer readable storage media further comprising instructions to sanitize the set of results prior to the classification.

11. The computer program product of claim 10, the computer readable storage media further comprising instructions to remove private details from the set of results.
