Method and system for modifying scanning document

The invention discloses a method and system for modifying a scanning document, which solves the problem of relatively low accuracy of a method for modifying a scanning document in the prior art. The method provided by the invention comprises the following steps: receiving the identification document of an initial document after optical character recognition (OCR); modifying the identification document, and recording the modification; receiving an emendation document obtained when an emendation user emendates the modified identification document; obtaining the emendation accuracy rate of the emendation user according to the emendation result of the modified content in the emendation document; and judging whether the emendation accuracy rate is larger than the preset value or not, and if the emendation accuracy rate is larger than the preset value, outputting the emendation document. The technical scheme provided by the invention is beneficial to the enhancement of the accuracy for modifying the scanning document.
