Method for searching similar exercises, computer device and storage medium

Abstract

The invention relates to a method for searching similar exercises, a computer device and a storage medium. The method comprises the following steps: S1, receiving text information of exercises; S2, extracting a knowledge point set corresponding to the exercises; extracting an error-prone point set; S4, finding out all knowledge points of which the association degree is greater than an associationdegree threshold value and the difficulty difference value is less than a difficulty threshold value from the knowledge point spectrogram; S5, according to the learning condition vector, extracting all knowledge points of which the learning conditions are smaller than a learning condition threshold value, and forming a to-be-screened knowledge point set by the knowledge points; S6, judging whetherthe to-be-screened knowledge point set is empty or not, if yes, adjusting a related threshold value, and returning to S4; otherwise, entering S7; and S7, finding out an exercise with the highest similarity with the to-be-screened knowledge point set from a question bank as a similar exercise of the exercise. According to the invention, the learning path can be customized according to the currentlearning condition of the user, and teaching is performed according to materials.

Description

technical field

[0001] The invention relates to the field of searching learning materials, in particular to a method for searching similar exercises, computer equipment and storage media. Background technique

[0002] The existing learning tools for children to sort out wrong questions in the industry, smart phone APPs, wrong question printers or other smart devices that assist learning, only allow users to digitally organize learning materials by taking pictures, or through a traditional The thermal printer prints out the learning materials, which is convenient for studying in the future. It is a simple application of various learning tools in the scene where students sort out wrong questions or organize other learning materials.

[0003] The process of sorting out the wrong questions for students actually needs to sort out the knowledge points involved behind the questions through the wrong questions in this way, the reasons for students' wrong questions, what pitfalls gen...

Examples

Embodiment 1

[0045] Embodiments of the present invention provide a method for finding similar exercises, such as figure 1 shown, including the following steps:

[0046] Step 1. Receive the text information of the exercises.

[0047] Step 1 can be achieved in the following three ways:

[0048] 1. Accept the picture of the exercise and convert the picture into text information.

[0049] A commonly used method, such as an OCR algorithm, may be used to convert the picture into text information, which is not limited here. The OCR algorithm adopted in this embodiment is the algorithm provided by the third-party open platform (such as Baidu AI open platform), by calling the OCR interface provided by the third-party open platform, the text information contained in the picture is extracted, and the picture is realized. The purpose of converting to text information.

[0050] 2. If the user's mobile phone has a built-in OCR function, it is also possible to directly convert the text information af...

Embodiment 2

[0106] The present invention also provides a computer device for searching for similar exercises, including a memory, a processor, and a computer program stored in the memory and operable on the processor. When the processor executes the computer program, the present invention is realized. Steps in the above method embodiment of the first embodiment of the invention.

[0107] Further, as an executable solution, the computer equipment for finding similar exercises may be computing equipment such as desktop computers, notebooks, palmtop computers, and cloud servers.

[0108] Further, as an executable solution, the so-called processor can be a central processing unit (Central Processing Unit, CPU), and can also be other general-purpose processors, digital signal processors (Digital Signal Processor, DSP), application specific integrated circuits (Application Specific Integrated Circuit, ASIC), Field-Programmable Gate Array (Field-Programmable Gate Array, FPGA) or other programmab...
