Problems solved by technology

[0005] The existing title entry system is not highly automated. When assembling questions and answers, there is a lack of automatic detection to filter out obviously wrong assembly errors; when storing questions, the questions cannot be accurately assigned to appropriate chapters; , it is easy to identify errors
The workload of manual review is relatively large, and the accuracy of manual review is not high

Embodiment 1

[0066] see Figure 1-Figure 6 , this application provides a system for recording questions based on digital educational resources, including

[0067] Upload data, the user takes pictures of the questions, and uploads the test questions that need to be entered on the pictures to the system;

[0068] When uploading data, the user can choose to upload a single question or a full page. If the option of uploading a single question is selected, the steps of automatic question segmentation and question and answer assembly steps will be skipped.

[0069] Image preprocessing, dewatermarking and light compensation processing of uploaded images to improve the clarity of the image;

[0070] Questions are automatically segmented, and each question and answer area is automatically identified and divided;

[0071] When the topic is automatically segmented, it is divided into the following steps:

[0072] S1. Detect image: perform overall detection on the input image, and determine the are...

Embodiment 2

[0107] The difference with embodiment 1 is:

[0108] In the topic storage stage, when classifying grades and subjects, it is necessary to extract the knowledge points of the topic. When there are multiple knowledge points in the same topic, compare them through the database, and directly divide the topic into the chapter where the last learned knowledge point is located. .

[0109] Specifically, the working principle of the recording system based on digital educational resources:

[0110] When uploading data, the user can choose to upload a single question or a full page. If the option of uploading a single question is selected, the steps of automatic question segmentation and question and answer assembly will be skipped, saving the uploading process;

[0111] In the OCR text recognition stage, the topic is recognized three times; when the recognition results are the same for multiple times, the accuracy of the entry topic can be guaranteed, and the workload of manual reading...

Abstract

The invention discloses a question recording system based on digital education resources, and the system comprises the steps: uploading data: enabling a user to take a picture of a question, and uploading a to-be-recorded test question on a picture to the system; preprocessing the image, and performing watermark removal and light compensation processing on the uploaded image; automatically segmenting the questions, and automatically identifying and segmenting areas to which each question and answer belong; carrying out OCR character recognition: recognizing characters, symbols, numbers and English characters in the image uploaded by the user; assembling the questions and the answers, wherein the questions and the answers are assembled in a one-to-one correspondence mode; carrying out duplicate checking, and removing existing repeated questions in the question bank; marking question attributes, and marking grades, subjects, chapters and knowledge point information to which test questions belong; enabling experts to check and delete questions which do not meet the standard; and inputting the data into a test question bank. When the system is used for uploading data, a user can selectto upload a single question and a whole page, and if a single question uploading option is selected, the steps of automatically segmenting the question and assembling the question and an answer are skipped, so that the uploading process is saved.

Description

technical field [0001] This application relates to the field of educational technology, in particular, to a system for recording titles based on digital educational resources. Background technique [0002] With the development of the field of educational technology, a large number of intelligent hardware devices and digital educational resources have entered the campus, and we empower teaching products through AI and other technical means. [0003] The examination needs to be reformed, and the propositions need to be modernized. Now we all hope to have a practical and easy-to-use question recording system to assist us in online education and online paper output. We can classify, store and manage the test questions for examination and assessment, and at the same time, according to certain settings, automatically Generate online test papers. At the same time, answering questions has always been a rigid need of the K12 student group. No matter homework or evaluation, it is an...
