Description

Technical Field

[0001] The present invention relates to the field of smart education technology, and in particular to a method, storage medium, and device for recording new teaching aids based on old teaching aids. Background Art

[0002] Under the current trend of educational informatization, traditional paper resources often need to be converted into electronic resources for use, such as converting teaching aids, test paper resources, and lesson plan resources into electronic files for teachers to use.

[0003] As educational resources continue to improve, supplementary materials, such as test questions, will keep pace with the times. Supplementary materials will be constantly updated, with some versions experiencing significant differences while others experience smaller ones. Currently, new supplementary materials are typically recorded electronically in their entirety. If the new supplementary material differs little from the old, the recording cycle will be long and resource reuse will be low. Therefore, it is crucial to effectively utilize old supplementary materials and update them based on the old. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention aims to provide a method, storage medium and device for recording new teaching aids based on old teaching aids.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A new teaching aid recording method based on the old teaching aid, the specific process is:

[0007] S1. Collect page images of each page of the new teaching supplementary material, and divide the test questions on each page image of the new teaching supplementary material into independent test question blocks, and obtain the serial number of each test question block on the corresponding page;

[0008] S2. Obtaining page information of old supplementary teaching materials and test question resource information corresponding to each page from a database; the page information includes a page image and / or page text data and a page number; the test question resource information includes text data and / or an image of each test question block contained in the page, a sequence number of each test question block, and coordinate data of each test question block;

[0009] S3, comparing the page images or page text data of each page of the old teaching supplementary material with the page images or page text data of each page of the new teaching supplementary material in sequence for similarity; when the similarity between a certain page of the old teaching supplementary material and a certain page of the new teaching supplementary material is higher than the similarity between the two pages of the old teaching supplementary material and the new teaching supplementary material, and is higher than a preset first similarity threshold, the two pages of the old teaching supplementary material and the new teaching supplementary material are corresponding pages;

[0010] S4. After determining the pages corresponding to the new and old supplementary teaching materials, compare the similarity of the text or image of the question blocks of each serial number on the two pages. If the similarity between the two question blocks is greater than a preset second similarity threshold, they are determined to be the same question; otherwise, they are determined to be different questions.

[0011] If the question blocks with the same serial number in the pages of the new and old supplementary teaching materials are the same question, the page marked with the old supplementary teaching materials can be fully reused;

[0012] If there are question blocks with the same serial number on the corresponding pages of the new and old supplementary teaching materials, but they are different questions, then the question block of the new supplementary teaching materials will be compared with other question blocks on the corresponding pages of the old supplementary teaching materials. If the comparison finds that there is a question block on the corresponding page of the old supplementary teaching materials that is the same question as the question block in the new supplementary teaching materials, then the question block in the old supplementary teaching materials will be marked as partially reusable;

[0013] If the question blocks with the same serial number on the pages corresponding to the new and old supplementary teaching materials are different questions, and the question blocks are different from the other question blocks on the pages corresponding to the old supplementary teaching materials, the pages corresponding to the old supplementary teaching materials will be marked as non-reusable.

[0014] S5. For a page of the old supplementary teaching material that can be fully reused, the page number of the page information of the old supplementary teaching material is modified to the page number of the page corresponding to the new supplementary teaching material, and the modified page information and test question resource information of the page of the old supplementary teaching material is directly used as the page information and test question resource information of the page corresponding to the new supplementary teaching material;

[0015] If there are partially reusable question blocks in the page of the old supplementary teaching materials, the serial number and coordinate data of the question block in the question resource information of the page of the old supplementary teaching materials are modified to the serial number and coordinate data of the corresponding question block in the page corresponding to the new supplementary teaching materials, and the page information and question resource information of the modified page of the old supplementary teaching materials are used as the page information and question resource information of the page corresponding to the new supplementary teaching materials;

[0016] If a page of the old supplementary teaching materials cannot be reused, the page information and test resource information of the corresponding page in the new supplementary teaching materials need to be re-entered and stored in the database;

[0017] S5. Finally, the page information of each page of the new supplementary teaching materials and the test question resource information are stored in the database to replace the page information of each page of the old supplementary teaching materials and the test question resource information.

[0018] The present invention also provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and the computer program implements the above method when executed by a processor.

[0019] The present invention also provides a computer device, comprising a processor and a memory, wherein the memory is used to store a computer program; and when the processor is used to execute the computer program, the above method is implemented.

[0020] The beneficial effects of the present invention are as follows: by comparing and verifying the differences between new and old supplementary materials, the method can confirm whether the old supplementary material data can be reused, effectively solving problems such as the long recording cycle of new supplementary materials and low resource reuse rate. It can also effectively avoid the problem of database data redundancy caused by the large number of repeated test questions in the database. DETAILED DESCRIPTION
