For the convenience of understanding of those skilled in the art, before the technical solutions of the present invention are introduced, the following terms are first explained:
examination points are: the examination outline has a plurality of examination points, and the examination points are knowledge points to be examined in the examination. Corresponding examination points are listed in an examination outline corresponding to a specific examination type, and test questions are customized for the examination points listed in the examination outline in the examination process so as to conduct investigation.

In the embodiment of the present invention, in order to achieve the purpose of recommending test questions to a student in a targeted manner according to the learning ability of the student and the outline of the examination, it is necessary to recommend test questions to the student in a targeted manner according to the examination frequency of the examination points and the examination point ability value of the student, so that the student can accurately practice the examination points which are not mastered by the student.
According to an embodiment of the present invention, a method for intelligently recommending test questions is provided, as shown in fig. 1, the method includes:
s102, determining the frequency of a plurality of examination points;
after the test type of the examination to be taken by the student is determined, the test outline corresponding to the test type is obtained, test point distribution is determined from the test outline, then the importance degree of the test points is determined according to the test outline, then the scores of the test points in the previous examinations are obtained, and the test frequency of the test points is determined according to the importance degree of the test points and the scores of the test points in the previous examinations. In a specific application scenario, a plurality of examination points exist in the examination outline. In this embodiment, a plurality of examination points of the examination are obtained through an examination outline corresponding to the examination type.
In an actual application scenario, the examination strength of each examination point in the examination is different, that is, the score of each examination point in the examination is different. Therefore, the index of frequency of examination is needed to indicate the examination strength of the examination point in the examination.
Optionally, in this embodiment, determining the reference frequencies of the multiple test points includes, but is not limited to: determining the fraction of each examination point in a plurality of examinations; and determining the reference frequency of each test point according to the fraction of each test point.
Specifically, the examination type with year as the unit in the examination season is explained, the fraction occupied by the examination point in the examination of nearly three years is obtained, and the examination frequency of the examination point is determined according to the fraction occupied by the examination point. And the examination type taking the quarter as a unit in the examination season is used for explaining, and the fraction occupied by the examination point in four examinations in one year is obtained to determine the examination frequency of the examination point. It should be noted that the sum of the reference frequencies of all the points under test is 1.
Optionally, in this embodiment, determining the reference frequency of each test point according to the fraction occupied by each test point includes, but is not limited to: determining the sum of the fractions of each examination point in multiple examinations according to the fraction of each examination point; determining a total score for a plurality of tests; and determining the reference frequency of each test point according to the sum of the scores and the total score.
Specifically, for example, the test types in year units in the test seasons are described, the scores of the examination points a in the test of the last three years are obtained as 1 point, 2 points and 1 point, and the total score of the test types is 10 points, and the frequency of the examination points a is calculated as (1+2+ 1)/(10 +10+10) — 2/15, so that the frequency of the examination points a can be found to be 2/15.
Still, the examination types based on years in the examination season are explained, and the specific examination points, the scores of the examination points and the distribution of the examination frequency in the last three years are shown in the following table 1:
| examination point | For 16 years | 17 years old | 18 years old | Frequency test |
| A | 1 | 2 | 1 | 2/15 |
| B | 2 | 2 | 2 | 1/5 |
| C | 3 | 5 | 4 | 2/5 |
| D | 2 | 0 | 1 | 1/10 |
| E | 2 | 1 | 2 | 1/6 |
Therefore, the examination frequency of the examination point of the last three years can be obtained.
S104, determining an examination point capability value corresponding to each examination point;
optionally, in this embodiment, determining the test point capability value corresponding to each test point includes, but is not limited to: determining the number of the test questions included in each examination point; acquiring test information of each test question; determining a test question right value corresponding to the test information; and determining the examination point capability value based on the examination question right limit value and the number of the examination questions.
In an actual application scenario, each test type corresponds to a different test outline, and test points to be examined in the test are listed in the test outline. Each examination point has a corresponding investigation form, such as a selection question, a short-answer question, a material question and the like, so that each examination point has a corresponding test question library, and the number of the test questions corresponding to the examination point is determined through the test question library corresponding to the examination point. It should be noted that, in a general case, a plurality of examination points may be examined simultaneously in a single examination question, for example, four examination points may be examined in a single-item selection question option, so that the single-item selection question may exist in the four examination question library. And determining the number of the test questions corresponding to the examination points according to the examination point-associated test question library.
After the test question library corresponding to the examination point is determined, the test information of each test question in the test question library is obtained, that is, the test record (that is, answer record) of each test question is obtained, and the accuracy, the test times and the like of the student on the test question at the examination point can be determined through the test record of the test questions. Wherein the test includes daily practice exercises, examinations, and the like.
Optionally, in this embodiment, the test information includes: test results of at least one test; accordingly, the test question authority value corresponding to the test information is determined based on the test information, including but not limited to: determining the number of tests based on the test information; and determining the test question right value based on the test result and the test times. The test information includes the test times of the test questions and the corresponding test results.
Further optionally, in this embodiment, determining the number of tests based on the test information includes: determining the number of test results; and determining the number of tests as the number of test results. For example, if the test results of one test question are "wrong-pair", the number of tests for the test question is 4.
Optionally, in this embodiment, determining the test question right limit value based on the test result and the test frequency includes: determining a test result of the current test; determining the test question authority value of the current test based on the test result of the current test, the test question authority value of the last test and the test times; wherein, the examination question right limit value is determined in an iterative mode through the examination question right limit value of the examination question in the last test.
For example, if the test information of one test question includes 4 tests, and the test results are "wrong-pair", the test question right value of the test question after the next test is obtained according to the test question right value of the last test, i.e., the "wrong-pair" of the third test, the test result "pair" and the test frequency "4" of the current test, and so on, in an iterative manner.
When the test question is not tested, the initial test question weight limit value of the test question is 0.
Further optionally, in this embodiment, determining the test question right limit value of the current test based on the test result of the current test, the test question right limit value of the last test, and the number of tests includes the following two ways:
1) if the test result of the current test is correct, determining the test question authority value of the current test in a first iteration mode;
wherein the first iteration mode is as follows:
wherein C is the test question authority value of the current test, ClRight value of examination question for last test, TnAnd the number of times of the test is the number of times of the test.
2) And if the test result of the current test is wrong, determining the test question right value of the current test in a second iteration mode.
Wherein the second iteration mode is as follows:
wherein C is the test question authority value of the current test, ClRight value of examination question for last test, TnAnd the number of times of the test is the number of times of the test.
The examination question right limit value and the number of the examination questions can be obtained through the steps, and the examination point capability value is determined according to the examination question right limit value and the number of the examination questions.
Optionally, in this embodiment, the examination point capability value is determined based on the examination question right limit value and the number of the examination questions, including but not limited to: determining the sum of the examination question right values; and determining the examination point capability value based on the sum of the examination question weight limit values and the number of the examination questions.
The examination point capability value is the ratio of the sum of examination question weight values of all examination questions under the examination point to the number of the examination questions. Specifically, the examination point capability value can be obtained by the following formula:
wherein, C is the right limit value of the test questions, and n is the number of the test questions under the examination point.
S106, screening out at least one recommended examination point from the plurality of examination points according to the examination frequency and the examination point capacity value;
after the examination frequency and the examination point capability value are obtained through the above steps, the examination point needing the trainee to conduct the targeted exercise is determined according to the examination point and the examination point capability value, optionally, in this embodiment, the step of screening out at least one recommended examination point from the plurality of examination points according to the examination frequency and the examination point capability value includes, but is not limited to: determining an examination point sequence based on the examination frequency and the examination point capability value, wherein the examination point sequence comprises a plurality of examination points; and screening at least one recommended test point from the test point sequence.
Specifically, for example, all the examination points are divided into 1-level examination points, 2-level examination points and 3-level examination points according to the examination frequency of the examination points, wherein the 1-level examination points are key examination points, the 2-level examination points are secondary examination points, and the 3-level examination points are common examination points. And then, sequencing the examination points according to the numerical value of the ability value of the examination points of the student to obtain an examination point sequence, wherein the examination points with the same ability value of the examination points in the examination point sequence are sequenced according to the examination frequency of the examination points. For example, for 5 examination points with examination point capability value of-1, including 1 level 1 examination point, 2 level 2 examination points, and 2 level 3 examination points, in this case, for 5 examination points in the examination point sequence whose examination point capability values are all-1, the sequence is 1 level 1 examination point, next 2 parallel level 2 examination points, then 2 parallel level 3 examination points, that is, 1 level 1 examination point >2 level 2 examination points (parallel) >2 level 3 examination points (parallel). Accordingly, it can be seen that the sequence of test points is ordered with the test point capability value as a priority factor.
In another example, the test points may be sorted based on their test frequencies to obtain a test point sequence, and for the test points with the same test frequency in the test point sequence, the test points are sorted by the test point capability value. Accordingly, it can be seen that the sequences of points of interest are ordered with frequency reference as a priority factor. The specific sorting manner is similar to the above-mentioned manner, and is not described herein again.
In another example, the examination points are sorted by taking the product of the examination point capability value and the examination frequency of the examination points to obtain the examination point sequence. For example, the examination point capability values of the examination points A, B, C in the outline of the examination are 1, -1 and 0, respectively, and the examination frequencies of the examination points A, B, C are 0.1, 0.5 and 0.4, respectively, so that the ranking of the examination points A, B, C is A, C, B.
After the test point sequences are obtained, at least one test point sequence is obtained from the test point sequences according to a preset selection rule, for example, a recommended test point is obtained by taking the test point capability value of the student on the test point as a priority factor, or the recommended test point is selected by taking the test frequency of the student on the test point as a priority factor.
S108, screening out at least one recommended test question from the plurality of test questions corresponding to the at least one recommended examination point.
At least one recommended examination point in the examination sequence is obtained through the step 106, then a plurality of test questions corresponding to the recommended examination point are obtained, and at least one recommended test question in the recommended examination points is obtained through the size of the test question authority limit value.
Optionally, in this embodiment, the screening of the at least one recommended test question from the plurality of test questions corresponding to the at least one recommended examination point includes, but is not limited to: determining a plurality of test questions corresponding to each recommended examination point; determining the examination question authority value of each examination question; determining a test question sequence corresponding to each recommended examination point based on the test question authority value of each test question, wherein the test question sequence comprises a plurality of test questions; and screening at least one recommended test question from the test question sequence.
In an actual application scene, after the recommended test questions are determined, the test question authority values corresponding to the multiple test questions corresponding to each recommended examination point are determined. Then, a test question sequence corresponding to the examination point is determined according to the test question right limit value of the test questions, and then at least one recommended test question is screened from the test question sequence.
In another implementation scenario, at least one recommended examination point is obtained from the examination point sequence, and if there are multiple recommended examination points, the examination questions corresponding to the multiple recommended examination points are obtained, and the examination question sequence is determined according to the examination question right limit value of the examination questions. In the implementation scene, only one test question sequence exists, and the test question sequence comprises test questions corresponding to all recommended examination points, but does not correspond to one recommended examination point independently.
Both of the above two ways are feasible, and the specific implementation manner can be set according to practical use experience, and is not limited in any way.
According to the embodiment of the invention, the examination frequency of a plurality of examination points is determined, the examination point capability value corresponding to each examination point is determined, at least one recommended examination point is screened out from the plurality of examination points according to the examination frequency and the examination point capability value, and at least one recommended examination question is screened out from a plurality of examination questions corresponding to the at least one recommended examination point. The purpose of recommending test questions to the student pertinently according to the learning ability of the student and the test outline is achieved, the technical effect that the student accurately exercises the test questions to improve the learning efficiency is achieved, and the technical problem that the learning efficiency of the student is low due to the fact that the student pertinently recommends the test questions to the student based on the learning ability of the student and the test outline in the related technology is poor is solved.
