Abstract

A method, apparatus, and system are disclosed for computer assisted document modification. One embodiment is a method for software execution. The method automatically extracts articles, in a first phase, from documents to generate different zones of the articles. Different zones of the extracted articles are displayed. In a second phase, plural different zones are manually modified with a document correction tool.

Claims

1. ) A method for software execution, comprising:

automatically extracting articles in a first phase from documents to generate different zones of article regions in the articles;

displaying the different zones of the extracted articles; and

manually modifying, with a document correction tool, a plurality of the different zones in a second phase to reduce a number of errors that occurred in the first phase.

2. ) The method of claim 1 further comprising:

receiving input from a user;

based on the input, adding and removing zones that identify text and image regions to reduce the number of errors that occurred in the first phase.

3. ) The method of claim 1 further comprising:

displaying a page of an extracted article;

manually changing, with the document correction tool, a label of the page to one of advertisement or article to reduce the number of errors that occurred in the first phase.

4. ) The method of claim 1 further comprising, manually changing, with the document correction tool, a designation of zone semantics of at least one of the different zones to reduce the number of errors that occurred in the first phase.

5. ) The method of claim 4, wherein the designation of zone semantics is selected from the group consisting of author, title, body of text, page number, and footnote.

6. ) The method of claim 1 further comprising, displaying zones with different colors to visually distinguish plural zones from each other.

7. ) The method of claim 1 further comprising, modifying, in the second phase, zone segmentation, page semantics, zone semantics, in-page zone linking, and cross-page zone linking.

8. ) The method of claim 1 further comprising:

processing the documents through plural successive phases in the second phase;

ceasing to modify a document in the second phase if one of the plural successive phases fails to cure an error.

9. ) A method for software execution, comprising:

generating a plurality of separate document regions of articles in scanned documents that are input to an automated document processing phase;

displaying the separate document regions so different document regions are visually distinct; and

modifying, in response to input from a user, linkings between at least two of the document regions.

10. ) The method of claim 9 further comprising, changing a label of at least one text region to correct one of the errors, the label specifying relevance between the at least one text region and a page of an article in which the at least one text region occurs.

11. ) The method of claim 9 further comprising, correcting, in response to input from the user, a flow of the separate text regions to correct one of the errors, the flow providing a reading order of text regions in one of the articles.

12. ) The method of claim 9 further comprising, displaying arrows between the document regions to signify that the document regions belong to a same article.

13. ) The method of claim 9 further comprising:

simultaneously displaying side-by-side two pages of one of the articles;

correcting, in response to input from the user, plural linkings between document regions in the one of the articles to correct one of the errors.

14. ) The method of claim 9 further comprising, changing, in response to input from the user, reading order between plural document regions in separate pages of at least one article to properly reconstruct the at least one article.

15. ) The method of claim 9 further comprising, reassigning one text region from a first article to a second article in order to correct one of the errors and accurately reconstruct the second article.

16. ) The method of claim 9 further comprising:

correcting the linkings between plural document regions in plural different phases of a document correction tool;

outputting documents as being acceptable after passing the documents through the plural different phases n times, where n is an integer greater than one.

17. ) A computer system, comprising:

means for extracting, in a first phase, articles from documents to generate different zones of article regions in the articles;

means for manually modifying, with assistance of a software tool, how zones are divided to correct errors generated in the first phase;

means for manually modifying, with assistance of the software tool, how pages from articles are labeled to correct errors generated in the first phase;

means for manually modifying, with assistance of the software tool, how zones are labeled to correct errors generated in the first phase; and

means for manually modifying, with assistance of the software tool, how zones are linked together to correct errors generated in the first phase.

18. ) The computer system of claim 17 further comprising, means for correcting, with assistance of the software tool, how pages from articles are linked together to correct errors generated in the first phase.

19. ) Computer code executable on a computer system, the computer code comprising:

code to extract articles from scanned documents to generate different zones in the articles during an automated document processing phase;

code to receive the different zones in the articles in order to correct errors generated during the automated document processing phase;

code to correct, in response to user input, how zones are divided;

code to correct, in response to user input, how pages from articles are labeled;

code to correct, in response to user input, how zones are labeled; and

code to correct, in response to user input, how zones are linked together.

20. ) The computer code of claim 19 further comprising, code to correct how pages from articles are linked together.

21. ) A computer readable medium, comprising:

instructions for extracting articles in a first phase from documents to generate different zones in the articles;

instructions for displaying the different zones of the extracted articles; and

instructions for manually modifying, with a document correction tool, a plurality of the different zones in a second phase to reduce a number of errors that occurred in the first phase.

22. ) The computer readable medium of claim 21 further comprising:

instructions for receiving input from a user;

instructions for adding and removing zones that identify text and image regions to reduce the number of errors that occurred in the first phase.

23. ) The computer readable medium of claim 21 further comprising:

instructions for manually changing, with the document correction tool, a designation of zone semantics of at least one of the different zones to reduce the number of errors that occurred in the first phase.

24. ) The computer readable medium of claim 21 further comprising:

instructions for modifying, in the second phase, zone segmentation, page semantics, zone semantics, in-page zone linking, and cross-page zone linking.

25. ) The computer readable medium of claim 21 further comprising:

instructions for correcting, in response to input from a user, a flow of separate text regions to correct one of the errors, the flow providing a reading order of the text regions in one of the articles.

26. ) The computer readable medium of claim 21 further comprising:

instructions for displaying arrows between zones to signify that the zones belong to a same article.
