Abstract

Provided are methods and systems for knowledge discovery utilizing knowledge profiles.

Claims

1. A computer-based method for editing a fingerprint, the method comprising:

presenting, by one or more computer processors, to a user, at least one concept that comprises the fingerprint, the at least one concept represented by a term, wherein the term comprises one or more words having a long form and an associated short form, wherein the long form and the short form provide a representation of a frequency of an occurrence of the term;

determining, by the one or more computer processors, a calculated importance of the at least one concept by applying a correction algorithm selected from at least one of;

log 10(1+T/S),

(1/(S+1))exp,

log 10((T+1)/(S+1)), and

log(S+off),

wherein T is a total number of documents, S is a frequency of the at least one concept in all documents, and S+off>

1, 0.0001 or off is a user defined exponent;

presenting, by one or more computer processors, to the user, a user interface wherein the user can adjust the calculated importance of the at least one concept, wherein the calculated importance is a weight that is adjustable from −

1 to +1 or the calculated importance is an attribute expressing that the at least one concept is forbidden or required;

receiving, by one or more computer processors, an adjusted importance from the user;

and

applying, by one or more computer processors, the adjusted importance to the at least one concept.

2. The method of claim 1, wherein presenting, to the user, the at least one concept that comprises the fingerprint comprises displaying a list of a plurality of concepts to the user on a display device.

3. The method of claim 1, wherein the user interface comprises a first input and a second input, the first input corresponds to forbidding the at least one concept and the second input corresponds to requiring the at least one concept such that the user can select one of the first input or the second input.

4. The method of claim 1, further comprising performing, by the one or more computer processors, a search with the fingerprint such that the at least one concept having the adjusted importance is a query for the search.

5. The method of claim 1, further comprising performing, by the one or more computer processors, a search with a concept from the at least one concept that is required.

6. The method of claim 1, further comprising performing, by the one or more computer processors, a search with a concept from the at least one concept that is forbidden.

7. A system for editing a fingerprint, the system comprising:

a non-transitory, computer readable storage medium configured for storing textual data;

a processor, coupled to the non-transitory, computer-readable storage medium, wherein the non-transitory, computer readable storage medium comprises one or more programming instructions that, when executed, cause the processor to;

present, to a user, at least one concept that comprises the fingerprint, the at least one concept represented by a term, wherein the term comprises one or more words having a long form and an associated short form, wherein the long form and the short form provide a representation of a frequency of an occurrence of the term;

determine a calculated importance of the at least one concept by applying a correction algorithm selected from at least one of;

log 10(1+T/S),

(1/(S+1))exp,

log 10((T+1)/(S+1)), and

log(S+off),

wherein T is a total number of documents, S is a frequency of the at least one concept in all documents, and S+off>

1, 0.0001 or off is a user defined exponent;

present, to the user, a user interface wherein the user can adjust the calculated importance of the at least one concept, wherein the calculated importance is a weight that is adjustable from −

1 to +1 or the calculated importance is an attribute expressing that the concept is forbidden or required;

receive an adjusted importance from the user; and

apply the adjusted importance to the at least one concept.

8. The system of claim 7, wherein the programming instructions that, when executed, cause the processor to present, to the user, the at least one concept that comprises the fingerprint further cause the processor to display a list of a plurality of concepts to the user on a display device.

9. The system of claim 7, wherein the user interface comprises a first input and a second input, the first input corresponds to forbidding the at least one concept and the second input corresponds to requiring the at least one concept such that the user can select one of the first input or the second input.

10. The system of claim 7, wherein the non-transitory, computer-readable storage medium further comprises one or more programming instructions that, when executed, cause the processor to perform a search with the fingerprint such that the at least one concept having the adjusted importance is a query.

11. The system of claim 7, wherein the non-transitory, computer-readable storage medium further comprises one or more programming instructions that, when executed, cause the processor to perform a search with a concept from the at least one concept that is required.

12. The system of claim 7, wherein the non-transitory, computer-readable storage medium further comprises one or more programming instructions that, when executed, cause the processor to perform a search with a concept from the at least one concept that is forbidden.

13. A non-transitory, computer-readable medium having one or more computer-executable instructions embodied thereon for editing a fingerprint, the one or more computer-executable instructions causing a processing device to:

present, to a user, at least one concept that comprises the fingerprint, the at least one concept represented by a term, wherein the term comprises one or more words having a long form and an associated short form, wherein the long form and the short form provide a representation of a frequency of an occurrence of the term;

determine a calculated importance of the at least one concept by applying a correction algorithm selected from at least one of;

log 10(1+T/S),

(1/(S+1))exp,

log 10((T+1)/(S+1)), and

log(S+off),

wherein T is a total number of documents, S is a frequency of the at least one concept in all documents, and S+off>

1, 0.0001 or off is a user defined exponent;

present, to the user, a user interface wherein the user can adjust the calculated importance of the at least one concept, wherein the calculated importance is a weight that is adjustable from −

1 to +1 or the calculated importance is an attribute expressing that the at least one concept is forbidden or required;

receive an adjusted importance from the user; and

apply the adjusted importance to the at least one concept.

14. The computer-readable medium of claim 13, wherein the one or more computer-executable instructions that cause the processing device to present, to the user, the at least one concept that comprises the fingerprint further cause the processing device to display a list of a plurality of concepts to the user on a display device.

15. The computer-readable medium of claim 13, wherein the user interface comprises a first input and a second input, the first input corresponds to forbidding the at least one concept and the second input corresponds to requiring the at least one concept such that the user can select one of the first input or second input.

16. The computer-readable medium of claim 13, wherein the one or more computer-executable instructions that cause the processing device to perform the search further cause the processing device to perform the search with the fingerprint such that the at least one concept having the adjusted importance is a query.

17. The computer-readable medium of claim 13, wherein the one or more computer-executable instructions that cause the processing device to perform the search further cause the processing device to perform the search with a concept from the at least one concept that is required.

18. The computer-readable medium of claim 13, wherein the one or more computer-executable instructions that cause the processing device to perform the search further cause the processing device to perform the search with a concept from the at least one concept that is forbidden.
