Problems solved by technology

For example, teachers use online question generators to generate questions for students, and can get feedback from them to motivate students, but the disadvantage of this method is that it increases the burden on teachers, and because the content of the test may be different, it is difficult to discover the potential abilities of students and cognitive level

Embodiment 1

[0054] In this embodiment, it is necessary to obtain the historical question-making information of the students, and perform re-aggregation according to the students and the questions. The knowledge points in the question and the relationship between the knowledge points are obtained by manual labeling, and a knowledge graph is established to calculate the difficulty of each question and the student's own ability (that is, the state representation of the student's questioning) according to the students' history of doing the questions. In this embodiment, for example, students' homework is divided according to time and batches assigned by the teacher to obtain a total of 40 homework assignments, and then the difficulty of each question is estimated by the accuracy rate. For each student, their knowledge cognitive ability is measured according to the average score of all the knowledge point-based assignments they have completed, so students' knowledge recognition is dynamic and i...

Embodiment 2

[0088] see Figure 11 Shown is a schematic structural diagram of an electronic device, which includes a processor 610, a memory 620, an input device 630, and an output device 640; the number of processors 610 in a computer device may be one or more; the processor in an electronic device 610, memory 620, input device 630, and output device 640 may be connected via a bus or in other ways.

[0089] The processor 610 executes various functional applications and data processing of the electronic device by running the software programs, instructions and modules stored in the memory 620, that is, implements the topic recommendation method in various embodiments of the present invention.

[0090] The memory 620 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system and an application program required by at least one function; the data storage area may store data created according to the use of the terminal, and...

Embodiment 3

[0093] Through the above description about the implementation mode, those skilled in the art can clearly understand that the present invention can be realized by means of software and necessary general-purpose hardware, and of course it can also be realized by hardware, but in many cases the former is a better implementation mode . Based on this understanding, the essence of the technical solution of the present invention or the part that contributes to the prior art can be embodied in the form of a software product, and the computer software product can be stored in a computer-readable storage medium, such as a floppy disk of a computer , read-only memory (Read-Only Memory, ROM), random access memory (Random Access Memory, RAM), flash memory (FLASH), hard disk or optical disc, etc., including several instructions to make an electronic device (which can be a mobile phone, personal Computer, server, or network equipment, etc.) to execute the topic recommendation method of vario...

Abstract

The invention relates to a topic recommendation method, electronic equipment, and a computer-readable storage medium, and belongs to the technical field of data mining. The method includes: acquiring students' historical problem-making information; re-aggregating the topics in the historical problem-making information according to knowledge points, and Construct a knowledge map for each knowledge point; calculate the vector representation of each knowledge point according to the knowledge map, and calculate the relationship between the students' knowledge point cognition and the difficulty of the topic; based on the relationship between the student's knowledge point cognition and the difficulty of the topic, Construct the representation of students’ state of doing questions through the similarity function; use the neural network with attention mechanism to perform data fusion of the vector representation of knowledge points and the representation of students’ state of doing questions; update the representation of students’ state of doing questions; in the Markov decision-making process , to recommend questions based on the updated representation of the student's question-making state. The ability to personalize assignment topic recommendations based on a student's ability can improve learning efficiency, assess academic performance, and reduce the burden on teachers.

Description

technical field [0001] The invention relates to the technical field of data mining, in particular to a topic recommendation method, electronic equipment and a computer-readable storage medium. Background technique [0002] The development of the Internet has made online learning possible. The physical classroom is beginning to lose its monopoly as a learning place. The way students fantasized about studying at home can now be realized through online learning. Many researchers and educators are interested in online learning, hoping to improve and improve students' learning outcomes through online learning, and at the same time deal with the problem of reducing physical educational resources. Among them, in terms of online assignments, such as online quizzes, after-school exercises, virtual laboratories, and online literature searches, etc., play an important role in online learning. For example, teachers use online question generators to generate questions for students, and ...
