Abstract
A method and a device for generating a collection of incorrectly-answered questions are provided. The method includes: acquiring an image of a marked test paper (S); recognizing regions of respective questions in the marked test paper according to a pre-trained first region recognition model (S); recognizing a question whose marking result is incorrect in the marked test paper as an incorrectly-answered question according to a pre-trained incorrectly-answered question recognition model (S); and storing the region of the incorrectly-answered question in an incorrectly-answered question database to generate the collection of incorrectly-answered questions (S). The above solution may solve the problem of low efficiency in generating the collection of incorrectly-answered questions in the prior art.
