PURPOSE: To insert a correct answer category to a candidate category set of pattern recognition results by applying complementing rules consisting of relations of the correct answer category to the candidate category set automatically extracted from information, which an operator corrects, to following pattern recognition results to automatically correct the category of erroneously recognized patterns.
CONSTITUTION: Recognition results of a character recognizing device are inputted to an automatic complementing part 1, and this part 1 refers to a complementing rule table 2 to automatically complement an erroneously recognized character. This complementing part 1 is not operated for recognition results in the early stage but sends character recognition results to a manual correction control part 3 as they are, and a first candidate character of recognition results of each character is displayed on an operation part 6. The operator sees the displayed character and corrects the erroneously recognized character by a keyboard of the operation part 6; and when the correct answer exists in the candidate character set, following candidates are successively displayed to select the correct answer. When the correct answer does not exist in the candidate character set, the correct answer character is inputted by KANA(Japanese syllabary)-KANJI(Chinese character) conversion input, and manual correction results are displayed.
