For the embodiments of the present application, the second user is typically a student. The electronic device may obtain the answer results of the test questions such as the job and the test paper of the second user in advance, and analyze the answer results of the test questions of the second user. Based on the current exercise information, the electronic equipment determines the answer result of the current exercise of the second user from the answer result of the test questions of the second user, and determines the second user information with the wrong exercise history as the second user name list information so as to determine the wrong name list of the exercise.

And if the electronic equipment detects that the operation instruction corresponds to the trigger command, recording the current time point. For example, when the operation instruction triggered by the first user is a "next page" non-trigger command, that is, the first user plays a next slide, the recording time operation is not required.
In step S1022, based on the time point, the video and the exercise information corresponding to the video are obtained.
For the embodiment of the application, the electronic device can record a plurality of time points of the first user at the teaching end, determine the time point corresponding to the operation of "start recording" as the entry time point, determine the time point corresponding to the operation of "end recording" as the exit time point, and determine the video between the entry time point and the exit time point as the explanation video of the problem.
For example, the entry time point is 14 points 23 minutes 54 seconds, the exit time point is 14 points 27 minutes 35 seconds, and the time period video between 14 points 23 minutes 54 seconds and 14 points 27 minutes 35 seconds is determined as the explanation video of the problem.

Carrying out semantic recognition on characters: the electronic device may pre-process, feature extract, and enter the model by pre-processing the text. Preprocessing the characters: performing word segmentation processing on characters, splitting a sentence into a plurality of parts, and performing corresponding matching on the plurality of parts based on a dictionary; and (3) carrying out feature extraction on the characters: feature extraction can be performed based on a TF-IDF (Term Frequency-Inverse text Frequency) model; entering text into the model: the characters can be input into a pre-trained FastText model to extract key information in the characters.
Step S10232, judging whether the video corresponds to the exercise information corresponding to the video based on the semantic recognition result.
For the embodiment of the application, based on the semantic recognition result, the electronic device determines whether the current video corresponds to the problem, that is, whether the video is explained as the problem. If the video corresponds to the exercise, whether the video is a complete explanation video of the exercise is judged.
For example, the subject is 21, and 21 has 21. (1), 21. (2) and 21. (3), and the electronic device compares the semantic recognition result with the subject content based on the semantic recognition result to determine whether the video explains all the contents of 21 subjects.
And step S10233, if the video does not correspond to the exercise information corresponding to the video, preprocessing the video.
