ABSTRACT:
A method of correcting a text in a data processing system is described. The method includes the step of locating a first incorrect character in the text. A character list of alternative characters for the first incorrect character is then shown to the user who replaces the first incorrect character with a correct character from the character list. The change of the first incorrect character is then propagated through a remainder of the text in accordance with a matching score and a language probability score of the remainder of the text with respect to the correct character to correct any subsequent incorrect character in the text.
