Abstract
To make it possible to extract a value with a high accuracy without imposing a heavy burden on a user even in a case where the character string row of a value corresponding to a certain item within a document changes. Based on a value extraction rule of a registered document whose type is the same as that of an input document, a text block corresponding to a value is estimated from among text blocks included in the scanned image of the input document and the character string that is the value is extracted. Then, after a user modifies the text block corresponding to the extracted character string, a rule is derived for estimating a value block so that it is possible to estimate the modified text block as the text block corresponding to the value.
