Title: Method and device for automatic error detection and correction for computerized text files

Abstract: A method and device for automatic error detection and correction for computerized text files uses a two-step segmentation method. A sentence of the computerized text file is first segmented at the first segmentation step into an original format and then converted into a correct sentence in the second segmentation step. In the first segmentation step the original sentence is segmented into a series of characters and the characters are analyzed so that the original phonetic or pictographic codes of the characters are revealed. The sentence in the original format is then converted into a series of phonetic representative codes and/or pictographic representative codes. Words consisting the sentence are then selected from a lexicon to reconstruct the sentence. The reconstructed sentence is then segmented again so that the errors in the original sentence are detected and corrections thereof are suggested.
