As expected, the proposed approach is efficient for diacritics, apostrophes and 1 letter modifications (DIACR, APOST, MOD1C).
it is worth noticing that in our approach, as the lexicon used in the correction step is not exhaustive, we observe 80 added errors due to the fact that some words, which were correct in the raw text, but not present in the lexicon, have been erroneously modified into an in-vocabulary form.
