1. An information processing system, comprising:
at least one memory that stores instructions; and
at least one processor that execute the instructions to:
obtain a scanned image obtained by scanning an original document;
execute character recognition processing on text blocks which are extracted from the scanned image, the text blocks indicating regions of character attributes;
estimate a text block including a character string associated with a predetermined data attribute out of the text blocks;
control a display device to display the scanned image and the character string included in the estimated text block; and
update, if the displayed character string is modified by a user, reference information based on the modified character string and display history information which indicates that a text block including the modified character string has displayed on the display device while the displayed character string is modified by the user, wherein the updated reference information is used such that the text block including the modified character string is to be estimated as a text block including a character string associated with the predetermined data attribute.
