Abstract

An exemplary embodiment of the invention is directed to a method for knowledge extraction, transfer and use of stored data, wherein data files in a computer system are checked. The method includes: providing a knowledge base for a data file type, the data file being of the data file type; applying the knowledge base to the data file; and; providing output data indicative of a result of the applying the knowledge base to the data file. This output data may then be printed or otherwise displayed. The computer system may also automatically correct the data file based on this output data.

Claims

1. A method of checking an input data file in a computer system, the method comprising:

providing a knowledge base for a data file type, said knowledge base including similar correct data files of said data file type and said input data file being of said data file type;

applying said knowledge base to the input data file; and

providing output data indicative of a result of said applying said knowledge base to the input data file.

2. The method of claim 1 wherein said knowledge base further includes local knowledge and global knowledge.

3. The method of claim 2 wherein said providing said knowledge base comprises:

providing said local knowledge of said knowledge base from a user; and

providing said global knowledge of said knowledge base from the computer system.

4. The method of claim 1 wherein said knowledge base further includes a plurality of rules.

5. The method of claim 4 wherein said providing said knowledge base comprises:

extracting said rules from said similar correct data files on a directory structure.

6. The method of claim 4 wherein said providing a knowledge base comprises:

learning said rules from users.

7. The method of claim 1 wherein the data file comprises a document data file or a drawing data file.

8. The method of claim 1 further comprising:

correcting the input data file based on said output data.

9. The method of claim 1 wherein said output data comprises error data, list data of non-error items, list data of error items, or statistical data.

10. The method of claim 1 further comprising:

generating a readable form of said output data.

11. The method of claim 10 wherein said generating said a readable form of said output data comprises printing or displaying said output data.

12. A storage medium encoded with machine-readable program code for checking an input data file in a computer system, said program code including instructions for causing the computer system to implement a method comprising:

providing a knowledge base for a data file type, said knowledge base including similar correct data files of said data file type and said input data file being of said data file type;

applying said knowledge base to the input data file; and

providing output data indicative of a result of said applying said knowledge base to the input data file.

13. The storage medium of claim 12 wherein said knowledge base further includes local knowledge and global knowledge.

14. The storage medium of claim 13 wherein said providing a knowledge base comprises:

providing said local knowledge of said knowledge base from a user; and

providing said global knowledge of said knowledge base from the computer system.

15. The storage medium of claim 12 wherein said knowledge base further includes a plurality of rules.

16. The storage medium of claim 15 wherein said providing a knowledge base comprises:

extracting said rules from said similar correct data files based on a directory structure.

17. The storage medium of claim 15 wherein said providing a knowledge base comprises:

learning said rules from users.

18. The storage medium of claim 12 wherein the input data file comprises a document data file or a drawing data file.

19. The storage medium of claim 12 wherein said method further comprises:

correcting the input data file based on said output data.

20. The storage medium of claim 12 wherein said output data comprises error data, list of non-error items, list data of error items, or statistical data.
