Online course portrait construction method based on feature engineering

Abstract

The invention discloses an online course portrait construction method based on feature engineering, and relates to the field of online education platforms, intelligent education and teaching auxiliary tools. According to the method, a logic architecture and a technical process of a knowledge graph are introduced, a method combining multi-dimensional quantification and fuzzy evaluation is adopted, and the method comprises the following steps that S100, curriculum portrait related features are extracted, and the related features comprise curriculum difficulty; S200, course portrait data fusion is carried out; S300, curriculum portrait feature weight determination is carried out; and S400, course portrait data storage and drawing is carried out. According to the method, mass and uneven courses existing in the current online education platform are evaluated in a multi-dimensional and all-around manner, the course portraits are formed, the courses matched with the portraits of learners can be screened out, and the learning process of the learners is more personalized.

Description

technical field [0001] The invention relates to a method for constructing online course portraits based on feature engineering, and relates to the fields of online education platforms, smart education, and teaching aids. Background technique [0002] With the rapid development of information technology, people's production, living and working methods are changing, and the world we live in is becoming increasingly connected, connected and intelligent. The educational objectives and teaching models under the background of the traditional industrial age are no longer suitable for the needs of today's information and big data era. Various institutions and researchers have proposed many new innovations for the realization of smart education, such as the application and practice of online classrooms and flipped classrooms, changing the previous teaching mode, so that learners can get more time for independent learning And the corresponding learning resources to make the learning ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to propose a method for constructing online course portraits based on feature engineering. By introducing the logical structure and technical process of the knowledge map, and using the method of combining the combination weighting method and the linear weighting method, comprehensive and multi-angle The evaluation of course quality solves the problem of uneven quality of courses on the existing online education platform, and learners can choose courses that match their abilities and interests in a more targeted manner.
