The numbers in “[]” indicate the number of values affected by an edit operation. The 18 characters in the gold standard were all included in the machine-generated matrix. The characters superscripted with “$N” are considered equivalent to a corresponding character in the gold standard, either by their semantic equivalence (i.e.. $1), or by the experts’ decisions (i.e., $2–$6)
