Optical character recognition support system

A computer-implemented method for increasing a recognition rate of an optical character recognition (OCR) system, comprising:

• receiving at least one garbled word of an OCR output;
• removing noise after morphologically analyzing the at least one garbled word;
• and
• replacing garbled characters of the at least one garbled word with correct characters based on a frequent edit operation;
• determining a distance between the at least one garbled word and each of a plurality of candidate correct words;
• and
• selecting one of the plurality of candidate correct words as correct word using a score based on the distance.

A system for increasing a recognition rate of an optical character recognition (OCR) system, comprising:

• a memory device for storing program code;
• and
• at least one processor device operatively coupled to the memory device and configured to execute program code stored on the memory device to:
• receive at least one image;
• extract all vertical lines from the at least one image;
• add vertical lines at character areas;
• extract all horizontal lines from the at least one image;
• create an unlined image removing all the vertical lines and horizontal lines from the at least one image;
• determine a border of a vertical direction of the unlined image based on the total of pixels of rows in each column;
• and
• add vertical auxiliary lines in blank space between characters of the unlined image.
