Meanwhile, it can be known that the questions made by the students need to be updated after new test question answering records exist.
For the convenience of understanding, the first school segment of a student is taken as an example for explanation, and the practical application can be extended to other school segments.
Step 1: key factors available for recommending test questions are combed and stored in a corresponding database, and specifically, in the test question recommendation, two core entities are provided: students and test questions.
The introduction of students and test questions are performed separately as follows:
step 1-1: the characteristics of the student (denoted u) are as follows:
grade of year, as
Values are pre-initial upper (15), pre-initial lower (16), primary upper (17), primary lower (18), primary upper second (19), primary lower second (20), primary upper third (21) and primary lower third (22);
class type, is marked as
When the student class type is empty, the value is 1, the class type is cyanine class/school class and when the student class type is off class, the value is 2, the class type is target class and when the student class type is on class, the value is 3;
province, mark as
The value is directly the province where the student is (the missing value is 0);
market, record as
Taking the value as the city where the student is located (the missing value is 0);
degree of knowledge points, record
The method can be divided into classification types, such as four mastery degrees, namely, non-practice (1), weakness (2), general (3) and firmness (4);
difficulty list of over/error test questions, note
，
The value ranges from 0 to 1. Wherein n is the number of the test questions made by the student. It should be noted that, since the untrained knowledge points do not have question data,
the difficulty list only needs to take one element, and the average difficulty of the candidate test questions with the knowledge points can be set specifically;
list of set of knowledge points on which wrong test questions were made/written
，
Is the knowledge point set of the nth topic. Note: since the untrained knowledge points have no question data,
the knowledge point set list only needs to take one element, and the specific value of the element is the current knowledge point.
Step 1-2: the candidate test question (denoted as t) is characterized as follows:
grade of year, as
Values are pre-initial upper (15), pre-initial lower (16), primary upper (17), primary lower (18), primary upper second (19), primary lower second (20), primary upper third (21) and primary lower third (22);
province, mark as
Taking the value as the province where the test question is from (the missing value is temporarily set as-1);
market, record as
Taking the value as the market where the test question comes (the missing value is temporarily set as-1);
year, is recorded as
Taking the value as the year of the source of the test question;
examination classification, note
The value is taken as the type of examination. Wherein, if the question is a real question of the middle entrance examination and the type of the middle entrance examination simulation is 1, other types are 2, and the null value/missing value is 3;
difficulty, note as
The value is between 0 and 1;
set of knowledge points, denoted
And the value is taken as the knowledge point set of the question. For example (internal angles of triangles and, the nature of parallel triangles).
Through the combing of key factors in the personalized recommendation of the test questions, on one hand, the precision of subsequent personalized recommendation can be improved; on the other hand, the interpretability of subsequent recommendation can be ensured, because what key factors play a key role can be tracked back based on the recommendation result, and the user is informed of why the problem is solved, namely, the interpretability of the recommendation is improved.
And grading the mastery conditions of the students according to the answer records of the students. For easy understanding, the knowledge point grasping conditions in the embodiment of the application are divided into 4 levels, namely four levels of firmness, generality, no grasping and no exercise. In practical applications, adjustments and changes can be made based on actual traffic conditions. Wherein if the student does not have any answer record on the knowledge point, the student defaults to the non-exercise state. The knowledge point grasping condition of the student is calculated by various algorithms including a common IRT \ DKT algorithm and the like, and after the specific score of the grasping degree of the student on the knowledge point is calculated, the specific grade of the student can be obtained through a clustering algorithm or thresholds for dividing different stages based on the overall grasping condition distribution of the student on the knowledge point.
Calling candidate test questions with the knowledge points from a database as a candidate test question set according to the knowledge point mastering conditions of the students and the knowledge points required to be linked by the students; and calculating the scores of the candidate test question priorities and the scores of the difficulty matching degrees, and calculating the final score of the comprehensive matching degree. And sequencing the scores of the comprehensive matching degrees from large to small, and acquiring TopN candidate test questions as recommended test questions.
Specifically, the calculation can be performed through the following modules;
the test question priority calculation module is used for calculating the priority of the test questions, wherein the test question priority refers to the recommended priority of a certain candidate test question based on the current basic information of the student compared with the basic information of the candidate test question. A total of 4 conditions, year priority, region priority (including province and city), examination category priority, year priority, are considered. Since the priorities recommended by students in different grades are different, a priority matrix PR is constructed as follows:
wherein,
indicating the priority weight of the ith grade on the jth condition. For example, when
Indicating that the priority weight on the annual priority of the first grade of the primary school is 1 when
The priority weight of the regional priority in the grade of primary school is 1 when
The priority of the test class in the grade I of primary school is 1, when
It means that the priority weight in the annual priority of elementary school is 1.
It should be noted that the grade in this embodiment is divided into half a year, so that when the grade is divided into half a year
In time, the top three is shown.
Take three grades in junior middle school (calculating to predict the first grade) as a specific example, namely
To
These 8 rows. Suppose from
To
The five year segments are identical in priority and
there are differences in this year segment (i.e., first three lower). Next, specific priority weight values are given.
Calculating the test question priority score of the alternative test question t relative to the student u based on the priority matrix and the judgment condition

A comprehensive score calculating module for scoring based on the test question priority
Matching score with test question difficulty

，
Is a decay function, n is arranged inversely in time;
as the weight of the priority of the test question,
shows the test question priority of the t-th candidate test question relative to the student u,
the weight of the degree of difficulty matching is,
representing the difficulty matching degree of the t-th candidate test question relative to the n-th difficulty reference test question of the student u,
the filtering weight of the candidate test question of the tth track relative to the student u represents whether the candidate test question t needs to be filtered or not for the student u;
the initial period may be set to 0.5.
In order to simplify the Newton attenuation function of the version, the test question sequence is attenuated, and the closer the test question time is, the weaker the attenuation is, so that the recommendation precision is further improved. It should be noted that the order of the test questions made by the student is reversed, i.e. a larger n indicates that the question is farther from the current time. The introduction of the filtering weight not only improves the recommendation precision, but also meets the teaching and teaching research requirements (namely, the super-class test questions cannot be recommended), and further improves the use experience of the user.
In the optional embodiment, the test question priority score and the test question difficulty matching degree score are obtained through comprehensive calculation based on the relevant information (such as the grade, the class type, the knowledge point mastering condition, the question making record and the like) of the student and the relevant information (such as the difficulty, the knowledge point range, the age limit, the area and the like) of the test question, and then the comprehensive score of the candidate question is obtained based on the two scores, so that the comprehensive personalized test question sequencing and recommendation based on the student information are realized. In the step, through the construction of a plurality of tensors, key factors of students and test questions are fully integrated, and the recommendation precision can be remarkably improved. Meanwhile, the key factors can be used as interpretable factors for test question recommendation, such as a certain question is pushed for a certain student, because the difficulty of the question is matched with the ability of the student; for example, a certain question is pushed for a certain student because the question is in accordance with the region and grade of the student, and has high quality. Particularly, compared with the existing recommendation system based on complex models such as neural networks and reinforcement learning, the personalized recommendation scheme designed by the proposal does not need large-scale data training, has low model complexity, and can remarkably improve the topic recommendation efficiency of personalized recommendation. In addition, the scheme has good expandability, and only the tensor needs to be increased or modified.
And finally, the response data of the students can be returned, the related information of the students is updated, the knowledge point mastering condition of the students is judged again, and the recommendation result is updated and perfected. The scheme can be conveniently landed and applied, and has the advantages of low implementation cost, good effect and the like.
In summary, in the technical scheme of the embodiment of the application, key factors of personalized test question recommendation are extracted, including relevant factors of students (such as grade, class type, knowledge point mastering condition, question making record and the like) and relevant factors of test questions (such as difficulty, knowledge point range, year limit, area and the like), and compared with the previous recommendation scheme. When the key factors are combed, conventional information such as difficulty is considered, and factors related to teaching and teaching research such as regions and the like are considered. Because the requirements and difficulties for making questions are different in different regions, the factors are considered in the recommendation scheme, and the factors can be well combined with actual teaching. The combing of the key factors not only improves the recommendation precision, but also well improves the recommendation interpretability. In the actual topic deduction process, the key factors can be tracked reversely to play a dominant role in the recommendation, so that the factors can be output, and the interpretability of the recommendation is improved. According to the technical scheme of the embodiment of the application, based on the recommendation algorithm with the fusion of a plurality of quantities, on one hand, a plurality of key factors can be accurately fused into the final recommendation scoring result, and the recommendation accuracy is obviously improved; on the other hand, the recommendation algorithm can adjust corresponding scoring parameters according to actual service conditions, can be adapted to scenes of different subject sections, and has good interpretability on recommendation results; in addition, compared with the existing test question recommendation scheme, the recommendation scheme greatly reduces the complexity and the calculation amount of the model on the premise of ensuring the precision, improves the recommendation efficiency, and can be better used on the ground and in a large scale.
