As correction ratio is determined by the product of a number of ratios, each evaluating the various stages of malapropism correction (identifying suspects, raising alarms, and applying the correction), we believe it is a better indicator of overall performance than correction performance, which is a not-so-elegant product of an F-score and accuracy.
no matter which of the two is chosen as the bottom-line performance statistic, the results show that the newly proposed distributional concept-distance measures are clearly superior to word-distance measures.
