Patent

CA 2265060

The present invention is a computer-implemented method for calculating word accuracy. Word grouping accuracy values (260) are calculated (212) by using the character accuracy values (250) calculated by an OCR program present in a computer system. The present invention preferably uses these character accuracy values (250) to create a word grouping accuracy value (260). Various methods are employed to calculate the word accuracy (260), including binarizing the character accuracy values (250). modified averaging of the character accuracy values (250), and creating fuzzy visual displays of word grouping accuracy values (260). The calculated word grouping accuracy values (260) are then adjusted based upon known OCR strengths and weaknesses. and based upon comparisons to stored word lists and the application of language rules. In a system with multiple character recognition techniques. the system can compare the accuracy values (260) of different versions of the word groupings to find the most accurate version. Then, the most accurate version of the word groupings is kept.
