Problems solved by technology

[0003] In recent years, with the development of image recognition technology, a new form of test-question-based online education has emerged, that is, to upload test questions in the form of photos to search for answers. Due to the inherent shortage of the test question bank, it is impossible to include all the questions in ad

Abstract

The invention discloses a mining method, a production method and a system for high-quality data. The mining method of the high-quality data comprises the following steps: based on periodic characteristics and/or based on the same cluster or approximate cluster of a current hotspot, estimating to obtain related data information of high-quality test questions. According to the mining system, the mining method is combined with the crowdsourcing platform. By estimating related data information of high-quality test questions, the high-quality test questions are produced in advance, and the accuratecalling rate of photographed test questions is increased; and the A/B-level commissioning mode is more suitable for production of high-quality test questions, crowdsourcing user resources can be better concentrated, and the return on investment of production is better guaranteed.

Description

technical field [0001] The invention belongs to the field of network education technology, especially the field of machine learning auxiliary technology, and more specifically relates to a high-quality data mining method, production method and system. Background technique [0002] With the development of the Internet and artificial intelligence, online education is becoming more and more popular, and the use of artificial intelligence and machine learning in online education is also becoming more and more common. Especially in the online education of test questions, since a large number of test questions may be involved, the original one-question-one-answer model is difficult to adapt to the development of the situation. Therefore, machine learning technology has been vigorously developed, and various types of questions can be solved as much as possible. A classification solution, simplifying the development of the question bank and the difficulty of answering. [0003] In ...
