Modified Levenshtein distance algorithm for coding










Image Number 8 for United States Patent #7664343.

Methods and systems of mapping of an optical character recognition (OCR) text string to a code included in a coding dictionary by supplementing the Levenshtein Distance Algorithm (LDA) with additional information in the form of adjustments based on particular character substitutions, insertions and deletions together with weighting based on multiple alternatives for the OCR text string. In one embodiment, an OCR text string mapping method (100) includes receiving (110) an OCR text string, comparing (120) it with selected text strings from a coding dictionary, computing (130) modified Levenshtein distances associated with the comparisons by determining (140) substitution penalties, determining (150) insertion penalties, determining (160) deletion penalties and combining (170) the penalties, selecting (180) the best matching text string from the coding dictionary based on the modified Levenshtein distances, determining (190) whether a maximum threshold distance is met, and assigning (200) a code associated with the best matching text string to the OCR text string when met, and assigning (210) a null or no code when not met.
