5. A method for proofreading a document comprising: generating a document file positioning text according to the order of reading of Optical Character Recognition (OCR) processed text, based on output information which includes text obtained by an OCR processing of a source manuscript image and information of position of the text in the source manuscript image; detecting movement of a line which includes text in the document file produced by proofreading by a user; and reflecting results of proofreading of the document file in the output information; wherein the process of detecting movement comprises: calculating a weight indicating degree of matching between a line deletion operation of deleting the line which includes text in the document file and a line insertion operation or a line editing operation; determining the line as being moved if the line deletion operation and line insertion operation or line editing operation have the maximum weight; and wherein, if movement of the line is detected, the reflection process includes moving text constituting the line in the output information according to information of designation of the line obtained by calculating the weight.
