example 1
[0097] This example includes steps ①②③ above. In addition, when calculating the disciplinary score in step ②, according to the cumulative body movement distance and face movement distance of examinee 1 and examinee 2, the seat distance between examinee 1 and examinee 2, the distance between examinee 1 and examinee 2, The text similarity of the test questions and the score rate of the test questions of test taker 1 and test taker 2 are used to calculate the disciplinary score v of test taker 1 and test taker 2.
[0098] Specifically, in this example, η 1 The calculation formula is as follows:
[0099]
[0100] Among them, l 1 , l 2 They are the threshold of the sum of the cumulative distance of the face movement and the threshold of the sum of the cumulative body movement of the two tests, respectively, and their values can be determined by finding a better value through experiments;
[0101] n 2 The calculation formula is as follows:
[0102]
[0103] Among them,...
example 2
[0108] This example includes steps ①②③ above. And, when calculating the disciplinary score in step ②, the cumulative distance of body movement and the cumulative distance of facial movement of examinee 1 and examinee 2 are not considered (i.e. η 1 = 1), but only according to the seat distance between the seats of examinee 1 and examinee 2, the similarity of the text of the test questions of examinee 1 and examinee 2, and the score rate of the test questions of examinee 1 and examinee 2 to calculate the examination room of examinee 1 and examinee 2 Disciplinary Score v.
[0109] specific:
[0110] n 2 The calculation formula is as follows:
[0111]
[0112] It should be noted that when the seat distance between examinee 1 and examinee 2 is greater than 5, η 2 = 0, regardless of the result of similarity calculation of subjective questions, it will not be judged as "mutual plagiarism".
[0113] n 3 The calculation formula is as follows:
[0114]
example 3
[0116] This example includes steps ①②③ above. In addition, when calculating the disciplinary score in step ②, according to the cumulative body movement distance and face movement distance of examinee 1 and examinee 2, the seat distance between examinee 1 and examinee 2, the distance between examinee 1 and examinee 2, The text similarity of the test questions and the score rate of the test questions of test taker 1 and test taker 2 are used to calculate the disciplinary score v of test taker 1 and test taker 2.
[0117] Specifically, η 1 The calculation formula is as follows:
[0118]
[0119] Among them, l 1 , l 2 They are respectively the sum threshold of the cumulative distance of facial movement and the threshold of the sum of cumulative distance of body movement in the two examinations, which can be empirical values, and their values can be determined by experiments to find a better value.
[0120] n 2 The calculation formula is as follows:
