Abstract

A system generates a text document from a received document image. Searchable metadata elements may be assigned to all or part of the text document by a user or by a template used to generate the text document. The text document and the associated metadata elements may be stored to facilitate subsequent searching and retrieval of the text document based on contents of the text document and/or its associated metadata elements.

Claims

1. A method, comprising;

receiving a document image;

converting the document image into a text document;

obtaining searchable information relating to the text document;

associating at least one searchable metadata element with the text document based on the searchable information; and

storing the text document and the at least one searchable metadata element for subsequent retrieval based on the at least one searchable metadata element.

2. The method of claim 1, wherein receiving the document image comprises capturing the document image with an optical scanner device.

3. The method of claim 1, wherein receiving the document image comprises receiving an electronic version of the document image from a storage medium.

4. The method of claim 3, wherein the storage medium is accessible via a computer network.

5. The method of claim 1, wherein converting the document image into the text document comprises:

performing optical character recognition on the document image to recognize the text of the document; and

generating the text document to include the recognized text of the document.

6. The method of claim 1, further comprising:

retrieving a template including instructions for converting portions of the document image into the text document; and

converting the document image into the text document based on the template.

7. The method of claim 6, wherein retrieving the template comprises retrieving the template from a template database accessible via a computer network.

8. The method of claim 1, further comprising:

retrieving a template including instructions for assigning the at least one searchable metadata element to at least one portion of the text document corresponding to at least one portion of the document image; and

associating the at least one searchable metadata element to the at least one portion of the text document based on the template.

9. The method of claim 1, wherein storing the text document and the at least one searchable metadata element for subsequent retrieval comprises:

storing the text document and the at least one searchable metadata element on a server accessible via a computer network.

10. The method of claim 9, further comprising:

storing the document image together with the text document and the at least one searchable metadata element.

11. The method of claim 1, further comprising:

receiving instructions to modify the text document;

modifying the text document in response to the received instructions to generate a modified text document; and

storing the modified text document and the at least one searchable metadata element for subsequent retrieval based on the at least one searchable metadata element.

12. The method of claim 11, wherein the instructions include instructions to remove at least a portion of the text document.

13. The method of claim 12, wherein the instructions include instructions to correct at least a portion of the text document.

14. The method of claim 1, comprising:

determining a confidence level indicative of an accuracy of the text document relative to the document image; and

recapturing the document image when it is determined that the confidence level is below a predetermined threshold.

15. A system, comprising:

means for receiving a document image;

means for converting the document image into a text document;

means for obtaining searchable information relating to the text document;

means for associating at least one searchable metadata element with the text document based on the searchable information; and

means for storing the text document and the at least one searchable metadata element for subsequent retrieval based on the at least one searchable metadata element.

16. A system, comprising:

a document capture system configured to capture an image of a document; and

a processor system configured to;

identify text contained within the image;

generate a text document based on the identified text;

obtain searchable information relating to the text document;

associate at least one searchable metadata element with the text document based on the searchable information; and

transmit the text document and the at least one searchable metadata element to a database for subsequent retrieval based on the at least one searchable metadata element.

17. The system of claim 16, wherein the document capture system comprises an optical scanner.

18. The system of claim 16, wherein the processor system is further configured to:

assign at least one initial metadata element to the text document based on a template.

19. The system of claim 18, wherein the at least one initial metadata element is associated with an entirety of the text document.

20. The system of claim 18, wherein the at least one initial metadata element is associated with a portion of the text document identified in the template.

21. A method, comprising:

receiving an image document;

identifying text contained within the image document;

generating a text document based on the identified text;

obtaining searchable information relating to the text document;

associating at least one searchable metadata element with the text document based on the searchable information; and

storing the text document and the at least one searchable metadata element in a database for subsequent retrieval based on the at least one searchable metadata element.

22. A computer-readable medium containing computer-executable instructions, comprising:

one or more instructions for receiving a document image;

one or more instructions for converting the document image into a text document;

one or more instructions for obtaining searchable information relating to the text document;

one or more instructions for associating at least one searchable metadata element with the text document based on the searchable information; and

one or more instructions for storing the text document and the at least one searchable metadata element for subsequent retrieval based on the at least one searchable metadata element.

23. A method, comprising:

receiving a document image from a scanning device;

performing optical character recognition on the document image to generate a text document based on the document image;

receiving modifications to the text document;

generating a modified text document based on the received modifications;

identifying searchable information relating to the modified text document;

associating at least one searchable metadata element with at least one portion of the modified text document based on the searchable information; and

storing the modified text document and the at least one searchable metadata element for subsequent retrieval based on the at least one searchable metadata element.
