Abstract
Processing of an image obtained by scanning an original document and on which character recognition processing is executed on text blocks which are extracted from the scanned image. The text blocks indicate regions of character attributes which may have different data attributes. An estimate is made of the likelihood that a text block is associated with a predetermined data attribute, and a display is made of the scanned image and the character string included in the estimated text block. If the displayed character string is modified by a user, reference information is updated based on the modified character string and history information pertaining to the modification is displayed. The updated reference information is used to improve the estimate of the likelihood that the text block is associated with the predetermined data attribute.
