METHOD FOR AUTOMATICALLY CALCULATING RECOGNITION RATE OR MISRECOGNITION RATE OF CHARACTER RECOGNITION DEVICE

摘要

PURPOSE: To automatically calculate the recognition rate or misrecognition rate without troubling a user. ;CONSTITUTION: A document that the character recognition device recognizes and outputs is corrected by a user on an editing screen 105. In key input operation at this time, the number of corrected characters is counted. In another way, the number of characters decreased in editing operation among the characters recognized and outputted from the character recognition device may be used as the number of corrected characters. The misrecognition rate is calculated by dividing the number of corrected characters by the total number of characters recognized by the character recognition device. The recognition rate is calculated by subtracting the number of corrected characters from the total number of characters recognized by the character recognition device and dividing the result by the total number of characters recognized by the character recognition device. To find the recognition rate more strictly, the number of new characters which are manually inputted is added to the number of corrected characters and the total number of characters recognized by the character recognition device and said calculation is made.;COPYRIGHT: (C)1995,JPO
