Character recognition system, character recognition method, and recording medium

A character recognition method comprising:

• by a computer,
• recognizing a character included in an input image by using each of a plurality of character recognition models different from each other;
• determining any of a plurality of recognition results as a most likely recognition result by using a determination model based on the recognition result by each of the plurality of character recognition models and image feature information indicating a feature of the input image;
• revising the most likely recognition result based on a revision operation by a user;
• and
• retraining the determination model by referring to training data including information indicating a revision content for the most likely recognition result, the plurality of recognition results, and the image feature information.

A non-transitory recording medium that records a program causing a computer to function as a character recognition system, the program causing the computer to execute:

• recognizing a character included in an input image by using each of a plurality of character recognition models different from each other;
• determining any of a plurality of recognition results as a most likely recognition result by using a determination model based on the recognition result by each of the plurality of character recognition models and image feature information indicating a feature of the input image;
• revising the most likely recognition result based on a revision operation by a user;
• and
• retraining the determination model by referring to training data including information indicating a revision content for the most likely recognition result, the plurality of recognition results, and the image feature information.
