Problems solved by technology

[0002] Due to the cumbersome and inefficient way for teachers to manually judge the answers to test questions, the technology of automatically judging the answers to test questions has emerged. For example, for objective questions, a cursor reader or scanner can be used to automatically judge and give scores , but for subjective questions that contain mathematical expressions in the answer, it is difficult to realize the automatic judgment of the test questions through simple identification and comparison because the answers have relatively complex operation symbols and logic

Embodiment 1

[0036] Such as figure 1 As shown, the embodiment of the present invention provides a method for judging the answer to the test question, including:

[0037] Step 101, obtain a standard answer, the standard answer is the first mathematical expression, and convert the first mathematical expression into a string form;

[0038] In this step, the mathematical expression refers to an expression that is easy for users to understand, for example, the first mathematical expression is The expression in the form of a string is an expression that is easy for the computer to understand, such as an expression in Latex format. After converting the first mathematical expression into a string form, it is 3y^2z\left(3+\frac{7x+5 }{1+y^2}\right), the first mathematical expression is used as a reference to judge whether the answer is correct, it can be entered by the teacher, or it can come from the question bank.

[0039] Step 102, obtaining an answer, the answer is a second mathematical expre...

Embodiment 2

[0049] Such as figure 2 As shown, on the basis of Embodiment 1, the embodiment of the present invention provides a method for judging the answer to the test question, which can be based on the interaction process between the server and the terminal, and the interaction process between the server and the terminal is used to realize the teacher In the scenario where homework is assigned, students complete the homework, and the server automatically corrects the homework, the following takes the server as the execution subject as an example to specifically introduce this embodiment:

[0050] Before the above step 101, obtaining the standard answer, it also includes: step 1010, receiving the first terminal data sent by the first terminal, the first terminal data including the above standard answer and the question information corresponding to the above standard answer;

[0051]Before this step, the teacher first logs in to the server through the first terminal to assign homework. ...

Embodiment 3

[0060] Such as image 3 As shown, the present embodiment provides a device for judging the answer to a test question, which includes: a standard answer acquisition unit 1, used to obtain a standard answer, the standard answer is a first mathematical expression, and the first mathematical expression is converted into a character string form; answer answer acquisition unit 2, used to obtain answer answer, answer answer is the second mathematical expression, the second mathematical expression is converted into character string form; operation unit 3, used for the first mathematical expression of character string form The formula and the second mathematical expression are subtracted or divided, and the result of the operation is obtained; the judging unit 4 is used to perform the subtraction operation on the first mathematical expression and the second mathematical expression in the form of a character string, If the result of the operation is 0, then it is judged that the answer ...

Abstract

The invention discloses a method and device for judging answers of test questions as well as a server, relates to the technical field of computers, and aims at carrying out automatic judgement on the answers to subjective questions in a mathematical expression form. The method for judging answers to test questions comprises the following steps: obtaining a standard answer which is a first mathematical expression, and converting the first mathematical expression into a character string form; obtaining a responding answer which is a second mathematical expression, and converting the second mathematical expression into a character string form; carrying out subtraction operation or division operation on the first mathematical expression and the second mathematical expression; when subtraction operation is carried out on the first mathematical expression and the second mathematical expression, judging that the responding answer is correct if the operation result is 0, and judging that the responding answer is incorrect if the operation result is not 0; when division operation is carried out on the first mathematical expression and the second mathematical expression, judging that the responding answer is correct if the operation result is 1, and judging that the responding answer is incorrect if the operation result is not 1.
