Abstract

A system and a method for providing characteristic data associated with a scanned document is provided. The characteristic data of the document may include a title, a creation date, a scan date, an author, a subject matter, a total page count, a starting page number, an ending page number, a color type, a document type, a language, and/or a document direction. The method includes analyzing a bitmapped image file of a document, determining at least one characteristic data of the document based on the analysis of the bitmapped image file, and linking the characteristic data to the bitmapped image file, wherein the characteristic data is useable by a document management system to identify the document in a search. Analyzing the bitmapped image of the document may include a natural language analysis technique, an optical character recognition analysis technique, an image layout analysis technique, and/or a color analysis technique.

Claims

1. A method for providing characteristic data associated with a document, the method comprising:

analyzing a bitmapped image file of a document;

determining at least one characteristic data of the document based on the analysis of the bitmapped image file; and

linking the characteristic data to the bitmapped image file,

wherein the characteristic data is useable by a document management system to identify the document in a search of the document management system.

2. The method of claim 1, further comprising scanning the document to create the bitmapped image file.

3. The method of claim 2, wherein the bitmapped image file is analyzed automatically after scanning the document.

4. The method of claim 1, further comprising merging the characteristic data and the bitmapped image file into a single document.

5. The method of claim 4, wherein merging the characteristic data and the bitmapped image file comprises adding the characteristic data to a header of the bitmapped image file.

6. The method of claim 1, further comprising:

storing the characteristic data in a characteristic data file; and

associating the characteristic data file with the bitmapped image file.

7. The method of claim 1, wherein analyzing the bitmapped image of the document comprises performing an image layout analysis.

8. The method of claim 7, wherein the image layout analysis determines an orientation of each page of the document and a position and a type for each object of each page of the document based on the bitmapped image file.

9. The method of claim 8, wherein the image layout analysis identifies the characteristic data based on the determined orientation and the determined object type and object position.

10. The method of claim 1, wherein analyzing the bitmapped image of the document comprises performing an optical character recognition analysis.

11. The method of claim 10, wherein the optical character recognition analysis translates text information in the bitmapped image file into machine readable text.

12. The method of claim 11, wherein the optical character recognition analysis identifies the characteristic data based on the machine readable text.

13. The method of claim 1, wherein analyzing the bitmapped image of the document comprises performing a natural language analysis.

14. The method of claim 13, wherein the natural language analysis detects a language and a keyword from the bitmapped image of the document.

15. The method of claim 14, wherein the natural language analysis identifies the characteristic data based on the detected language and keyword.

16. The method of claim 13, wherein the natural language analysis detects a language from the bitmapped image of the document, and further wherein, analyzing the bitmapped image of the document further comprises performing an image layout analysis.

17. The method of claim 16, wherein analyzing the bitmapped image of the document further comprises performing an optical character recognition analysis.

18. The method of claim 1, wherein analyzing the bitmapped image of the document comprises performing a color analysis to determine if the document is a color document.

19. The method of claim 1, wherein the characteristic data of the document is selected from the group consisting of a title, a creation date, a scan date, an author, a subject matter, a total page number, a starting page number, an ending page number, a color type, a document type, a language, and a document direction.

20. The method of claim 1, wherein analyzing the bitmapped image of the document comprises performing at least one of a natural language analysis, an optical character recognition analysis, an image layout analysis, or a color analysis.

21. The method of claim 1, further comprising:

receiving a search query at the document management system, the search query including a query item;

comparing the query item to the characteristic data; and

providing the bitmapped image file as a result of the search query based on the comparison of the query item to the characteristic data.

22. One or more computer-readable media having computer-readable instructions stored thereon that, upon execution by a processor, cause the processor to provide characteristic data associated with a document, the instructions configured to:

analyze a bitmapped image file of a document;

determine at least one characteristic data of the document based on the analysis of the bitmapped image file; and

link the characteristic data to the bitmapped image file,

wherein the characteristic data is useable by a document management system to identify the document in a search of the document management system.

23. A device for providing characteristic data associated with a document, the device comprising:

a characteristic data analyzer application, the characteristic data analyzer application comprising computer-readable instructions configured

to analyze a bitmapped image file of a document;

to determine at least one characteristic data of the document based on the analysis of the bitmapped image file; and

to link the characteristic data to the bitmapped image file,

wherein the characteristic data is useable by a document management system to identify the document in a search of the document management system;

a memory, wherein the memory stores the characteristic data analyzer application; and

a processor coupled to the memory, the processor configured to execute the characteristic data analyzer application.
