1. A computer-implemented method for text analysis, comprising: analyzing verification performed by a user on a recognized text obtained by character recognition of a document image, wherein the verification comprises changing an incorrect character identified by the user for a correct character identified by the user; identifying analogous changes of a first incorrect character for a first correct character; and initiating a training of a recognition pattern based on the identified analogous changes, wherein the recognition pattern is a pattern used in character recognition of the document image to generate the recognized text.
