Generating training documents

1. A method of generating training documents for training a classifying device comprising, with a processor:

determining a number of sub-samples in a number of original documents; and

creating a number of pseudo-documents from the sub-samples, the pseudo-documents comprising a portion of the number of sub-samples,

in which each of the pseudo-documents are created by deleting a number of the sub-samples through a jackknife statistical method.

2. The method of claim 1 , in which each of the pseudo-documents comprise less than all of the sub-samples.

3. The method of claim 1 , in which each of the pseudo-documents comprise all of the sub-samples.

4. The method of claim 1 , in which the sub-samples comprise a number of words, phrases, lines of text, or a combination thereof.

5. The method of claim 1 , further comprising training a classifying device to classify textual documents based on the pseudo-documents.

6. The method of claim 5 , further comprising classifying a number of test documents based on the training.

7. The method of claim 1 , further comprising training a classifying device to classify textual documents based on the original documents, the pseudo-documents, or a combination thereof.

8. The method of claim 1 , in which creating a number of pseudo-documents comprises creating at least 10 pseudo-documents per original document.

9. A device for training a classifying device, comprising:

a processor; and

a memory communicatively coupled to the processor, the memory storing:

a sampling module to, when executed by the processor, determine a number of sub-samples in a number of original documents;

a pseudo-document creation module to, when executed by the processor, create a number of pseudo-documents from the sub-samples, the pseudo-documents comprising a portion of the number of sub-samples, wherein each of the pseudo-documents are created by deleting a number of the sub-samples through a jackknife statistical method; and

a training module to, when executed by the processor, train a classifying device to classify textual documents based on the pseudo-documents.

10. The device of claim 9 , further comprising a classification module to, when executed by the processor, classify a number of test documents.

11. The device of claim 10 , in which the classification module classifies the test documents based on the training provided by the training module.

12. The device of claim 9 , in which the processor further stores the original documents and the pseudo-documents in the memory.

13. A computer program product for classifying documents, the computer program product comprising:

a non-transitory computer readable medium storing computer usable program code embodied therewith, the computer usable program code comprising:

computer usable program code to, when executed by a processor, determine a number of sub-samples in a number of original documents; and

computer usable program code to, when executed by a processor, create a number of pseudo-documents from the sub-samples, the pseudo-documents comprising a portion of the number of sub-samples,

in which each of the pseudo-documents are created by deleting a number of the sub-samples through a jackknife statistical method.

14. The computer program product of claim 13 , in which the computer program product is operated by a third party as a service.

15. The computer program product of claim 13 , further comprising computer usable program code to, when executed by a processor, train a classifying device to classify textual documents based on the pseudo-documents.

16. The computer program product of claim 13 , further comprising computer usable program code to, when executed by a processor, classify a number of test documents.
