Test question difficulty labeling method and device based on test paper structure and storage medium

Abstract

The invention discloses a test question difficulty labeling method and device based on a test paper structure and a storage medium. The test question difficulty labeling method comprises the steps of acquiring a test paper set with the same test paper attribute information in a test paper library; performing test paper structure analysis and test question information analysis on the test papers in the test paper set; constructing a test question difficulty transfer structure diagram of all test questions in the test paper set according to a test question difficulty relationship corresponding to each type of test paper structure preset by the system; and performing test question difficulty labeling on each test question based on the test question difficulty transfer graph. The test question difficulty transfer structure diagram of all test questions in the test paper set is constructed, and the system automatically performs difficulty value assignment on each test question according to the test question difficulty transfer structure diagram, so that automatic and batch labeling of the test question difficulty values is realized, and compared with a manual question-by-question labeling mode, the method is simpler and quicker, the test question difficulty value is obtained through the relative relation, and the marking basis of the test question difficulty value is more reasonable, accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of online education, in particular to a method, device and storage medium for marking the difficulty of test questions based on the structure of test papers. Background technique [0002] In order to provide online services such as photo search, intelligent practice, and homework correction, online education platforms generally need to be based on a powerful test question database. For the test questions in the test question database, in order to provide users with a more comprehensive user experience, the subject, grade, area and difficulty value of the test question are often marked with test question attribute labels, among which the subject, grade, region and other test question attribute labels can be obtained from the test paper of the test question It is automatically obtained from the resources, and the difficulty value labels of the test questions generally need to be marked one by one by the teache...

AI Technical Summary

Problems solved by technology

[0004] On the one hand, for a test question database with a capacity of 100 million or more, the number and frequency of test question updates are relatively large, which requires a lot of manpower and financial resources to mark the difficulty value of the test questions one by one. The cost of manpower, time and money larger

[0005] On the other hand, due to the subjective factors of the difficulty value of the test questions, multiple teachers have different evaluation standards for the same test question, resulting in deviations in the labeling of the difficulty value of the same test question

This characteristic makes it difficult to evaluate whether the difficulty value of a test question is reasonable

[0006] To sum up, it can be seen that the difficulty value labeling method of the existing test questions not only needs a lot of manpower, time and money costs, but also cannot determine whether the difficulty value of the test questions is reasonable due to the lack of labeling and review of the subjective evaluation of the difficulty value of the test questions
