Abstract

Claims (66)

1. A method, comprising:

performing optical character recognition (OCR) on an image of the first document; and

identifying, in the image of the first document, one or more of: textual information specific to a sender of the first document; and data formatting specific to the sender at least one of:

correcting OCR errors in the first document using at least one of textual information from a complementary document and predefined business rules;

normalizing data from the complementary document using at least one of textual information from the first document and the predefined business rules; and

normalizing data from the first document using at least one of textual information from the complementary document and the predefined business rules.

2. The method as recited in claim 1 , further comprising generating a list of hypotheses mapping the first document to a complementary document.

3. The method as recited in claim 2 , wherein the hypotheses are generated using:

textual information from the first document,

textual information from the complementary document, and

predefined business rules.

4. The method as recited in claim 2 , further comprising: determining a validity of the first document based on the hypotheses; and outputting an indication of the determined validity.

5. The method as recited in claim 1 , further comprising:

receiving an image of the first document

extracting at least a partial address of a sender of the first document from the image based on the OCR;

comparing the extracted at least partial address with content in a database; and

extracting additional content from the image of the first document.

6. A computer program product comprising computer readable program code embodied on a non-transitory computer readable medium, the computer code configured to perform the method as recited in claim 1 .

7. A system, comprising:

a processor; and

logic in and/or executable by the processor, the logic configured to perform the method as recited in claim 1 .

8. A method, comprising at least one of:

correcting OCR errors in a first document, and normalizing data from the first document based at least in part on a complementary document, wherein the data are normalized prior to determining a validity of the first document;

normalizing data from the complementary document using at least one of textual information from the first document and predefined business rules; and

outputting an indication of the determined validity.

9. The method as recited in claim 8 , further comprising determining the validity of the first document; and outputting an indication of the determined validity.

10. The method as recited in claim 9 , wherein the validity of the first document is determined by simultaneously considering:

textual information from the first document,

textual information from the complementary document, and

predefined business rules.

11. The method as recited in claim 8 , further comprising: receiving an image of the first document;

extracting at least a partial address of a sender of the first document from the image based on an OCR result;

comparing the extracted at least partial address with content in a database; and

extracting additional content from the image of the first document.

12. A computer program product comprising computer readable program code embodied on a non-transitory computer readable medium, the computer code configured to perform the method as recited in claim 8 .

13. A system, comprising:

a processor; and

logic in and/or executable by the processor, the logic configured to perform the method as recited in claim 8 .

14. A method, comprising:

performing optical character recognition (OCR) on a scanned image of a first document;

extracting an identifier from the first document;

identifying a complementary document associated with the first document using the identifier;

obtaining textual information of the complementary document;

generating a list of hypotheses mapping the first document to the complementary document using:

textual information from the first document,

the textual information from the complementary document, and

predefined business rules;

determining a validity of the first document based on the hypotheses; and

outputting an indication of the determined validity.

15. A computer program product comprising computer readable program code embodied on a non-transitory computer readable medium, the computer code configured to perform the method as recited in claim 14 .

16. A system, comprising:

a processor; and

logic in and/or executable by the processor, the logic configured to perform the method as recited in claim 14 .

17. A method, comprising:

extracting an identifier from an electronic first document;

using the identifier to identify a complementary document associated with the first document;

obtaining textual information of the complementary document;

determining a validity of a first document by simultaneously considering:

textual information from the first document,

the textual information from the complementary document, and

predefined business rules; and

outputting an indication of the determined validity.

18. A computer program product comprising computer readable program code embodied on a non-transitory computer readable medium, the computer code configured to perform the method as recited in claim 17 .

19. A system, comprising:

a processor; and

logic in and/or executable by the processor, the logic configured to perform the method as recited in claim 17 .
