A computer method of spelling correction comprises the steps of: a) storing a dictionary of valid words, b) for each input string to be checked comparing the input string to words in the stored dictionary to identify input strings not in the dictionary, c) for each input string not found in the preceding step, generating test words by a restricted set of edit operations which correct the most common errors comprising insertion, deletion, transposition and/or substitution, d) comparing the edited input string generated in the preceding step with words stored in the dictionary and e) generating a candidate word or candidate list of the words.
