Embodiment Construction
[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.
[0021] The object of the present invention is to provide a method, system, terminal and server for predicting answer scores. By collecting the user's answer data, and obtaining the number of correctly answered questions and the total number of questions under each difficulty coefficient of each knowledge type from the answer data, the correct answer rate is calculated. Through the preset ability value mapping table, the ...

The embodiment of the invention discloses a prediction method, a system, a terminal and a server of a test score and belongs to the technical field of question-answering ability evaluation. The method comprises the following steps of collecting answer data of a user; acquiring the number of right answers and the total number of questions under each difficulty coefficient; calculating a correct answer rate of each difficulty coefficient; mapping every correct answer rate into an ability value theta according to a preset ability value mapping table; calculating a scoring probability P difficulty of each difficulty coefficient; calculating a scoring probability P testing point of each knowledge type based on the weight of each difficulty coefficient; calculating a total scoring probability P total based on the weight of each knowledge type; predicting a test score based on the total scoring probability P total and the gross score of the test. The predicted test score is gained considering difference of the correct answer rate of different knowledge types, the different weights of different difficulty coefficients, and the different weights of different knowledge types. Test scores of users are predicted more accurately.
Description
technical field [0001] The invention relates to the technical field of question answering ability evaluation, in particular to a method, system, terminal and server for predicting answer scores. Background technique [0002] Examination is a process that everyone has experienced in modern life. Candidates often conduct mock tests on their abilities before the exam, and an online mock test system has become a very important development direction. The question bank of the online simulation test system will accumulate a large amount of user-made question data. How to predict the user's test score as accurately as possible based on the user-made test data is a very interesting and practical problem. The scoring system of the online simulation test in the prior art calculates the user's correct rate based on the user's answer data, and multiplies the user's correct rate by the total score of the test to obtain the test score. [0003] In the process of realizing the present inve...
