Abstract

A technology of the present invention is capable of objectively judging an ability of a proofreader who proofreads a digitized document by use OCR programs. A method of managing an ability of a proofreader who proofreads an electronic document generated from a recognition target document by executing a character auto recognition program, comprises a step of estimating a character count of potential mis-recognized characters contained in the electronic document, a step of detecting a mis-recognized character discover count as a mis-recognized character count with which the proofreader discovers the mis-recognized characters in the electronic document, a step of detecting a processing time spent for proofreading the electronic document, and a step of calculating a score relative to a proofreader ability based on a ratio of the potential mis-recognized character count to the mis-recognized character discover count per unit time.

Claims

1. A method of managing an ability of a proofreader who proofreads an electronic document generated from a recognition target document by executing character auto recognition programs, comprising:

estimating a character count of potential mis-recognized characters contained in the electronic document;

detecting a mis-recognized character discover count with which the proofreader discovers the mis-recognized characters in the electronic document;

detecting a processing time spent for proofreading the electronic document; and

calculating a score relative to a proofreader ability based on a ratio of the mis-recognized character discover count per unit time to the potential mis-recognized character count.

2. The method of managing an ability of a proofreader according to claim 1, further comprising:

executing a non-coincident character count between the electronic documents generated by executing plural types of character auto recognition programs with respect to the same recognition target document, and

executing a character count where preciseness of the character auto recognition for each character by the character auto recognition programs is shown by a degree of coincidence and is less than or equal to a predetermined value.

3. The method of managing an ability of a proofreader according to claim 1, further comprising:

calculating a degree of difficulty of a proofreading target electronic document on the basis of a ratio of the potential mis-recognized character count to a total character count of the electronic document;

calculating a proofreader ability level by averaging the scores with respect to the plurality of proofreading target electronic documents per predetermined range of the degree of difficulty; and

selecting an optimal proofreader corresponding to the degree of difficulty of the proofreading target electronic document.

4. The method of managing an ability of a proofreader according to claim 1, further comprising:

calculating a change in the score relative to the proofreader ability with respect to the operation time for consecutively proofreading the plurality of proofreading target electronic documents; and

setting the operation time based on the change in the score relative to the proofreader ability.

5. The method of managing an ability of a proofreader according to claim 4, further comprising:

evaluating the proofreader ability for every predetermined operation time; and

setting again the operation time on the basis of the change in the proofreader ability.

6. A system to manage an ability of a proofreader who proofreads an electronic document generated from a recognition target document by executing character auto recognition programs, comprising:

an information input/output unit detecting a mis-recognized character discover count with which the proofreader discovers the mis-recognized characters in the electronic document, and a processing time spent for proofreading the electronic document;

an information recording unit;

an information display unit; and

a control unit for counting a character count of potential mis-recognized characters contained in the electronic document, and calculating a score relative to a proofreader ability based on a ratio of the mis-recognized character discover count per unit time to the potential mis-recognized character count.

7. The system to manage an ability of a proofreader according to claim 6, further comprising a timer,

wherein the information input/output unit detects a start of the proofreading operation and an end of the proofreading operation, and

the timer counts a period of time from the start of the proofreading operation to the end of the proofreading operation.

8. The system to manage an ability of a proofreader according to claim 6, wherein the control unit, estimates the potential mis-recognized character count by executing a non-coincident character count between the electronic documents generated by executing plural types of character auto recognition programs with respect to the same recognition target document, or by executing a character count where preciseness of the character auto recognition for each character by a character auto recognition program is shown by a degree of coincidence and is less than or equal to a predetermined value.

9. The system to manage an ability of a proofreader according to claim 6, wherein the control unit

calculates a degree of difficulty of a proofreading target electronic document on the basis of a ratio of the potential mis-recognized character count to a total character count of the electronic document;

calculates a proofreader ability level by averaging the scores with respect to the plurality of proofreading target electronic documents per predetermined range of the degree of difficulty; and

selects an optimal proofreader corresponding to the degree of difficulty of the proofreading target electronic document.

10. The system to manage an ability of a proofreader according to claim 6, wherein the control unit

calculates a change in the score relative to the proofreader ability with respect to the operation time for consecutively proofreading the plurality of proofreading target electronic documents;

and

sets the operation time based on the change in the proofreader ability.

11. The system to manage an ability of a proofreader according to claim 10, wherein the control unit

evaluates the proofreader ability for every predetermined operation time;

and

sets again the operation time on the basis of the change in the proofreader ability.

12. A computer-readable program on a recording medium, executed by a computer, to manage an ability of a proofreader who proofreads an electronic document generated from a recognition target document by executing character auto recognition programs, comprising:

estimating a character count of potential mis-recognized characters contained in the electronic document;

detecting a mis-recognized character discover count as a mis-recognized character count with which the proofreader discovers the mis-recognized characters in the electronic document;

detecting a processing time spent for proofreading the electronic document; and

calculating a score relative to a proofreader ability based on a ratio of the mis-recognized character discover count per unit time to the potential mis-recognized character count.
