Embodiment 1

[0071] Such as figure 1 As shown, a method for constructing curriculum map based on network embedding includes the following steps:

[0072] S1. The concept extraction module crawls the course description and chapter name from the online learning website, and obtains the domain concept set through word segmentation filtering; performs phrase filtering on the domain concept set to obtain the concept words of the target course;

[0073] S2. The network embedding module, according to the concept words obtained by the concept extraction module, defines the text set and prerequisite concepts of the concept words, learns the concept representation through the network embedding method, and defines the structure vector v s and a text vector v t , the structure vector v s and a text vector v t Put it in the neural network for learning, and get a set of concept vectors;

[0074] S3. The course relationship derivation module outputs the course leader relationship according to the abo...

Embodiment 2

[0077] The method for constructing a course map based on network embedding provided in this embodiment is the same as that provided above, and each step is only further limited.

[0078] A method for constructing curriculum map based on network embedding, comprising the following steps:

[0079] S1. The concept extraction module crawls the course description and chapter name from the online learning website, and obtains the domain concept set through word segmentation filtering; performs phrase filtering on the domain concept set to obtain the concept words of the target course;

[0080] S2. The network embedding module, according to the concept words obtained by the concept extraction module, defines the text set and prerequisite concepts of the concept words, learns the concept representation through the network embedding method, and defines the structure vector v s and a text vector v t , the structure vector v s and a text vector v t Put it in the neural network for lea...

Abstract

The present invention provides a course map construction method based on network embedding, which is suitable for online education scenarios with a large number of courses. It is different from the inefficiency of traditional manual course path formulation, and can automatically and quickly generate a large number of course leader relationship maps. Learners of online education provide a reference for learning path planning. The innovation and advancement of the present invention are mainly reflected in two aspects: first, the network embedding method is used to vectorize concepts, and compared with other embedding methods, it can more accurately express the semantics of concepts and the relationship between concepts At the same time, it also avoids calculation difficulties caused by excessively high dimensions; second, uses concepts to represent courses, and then derives the leading relationship between courses through the leading relationship between concepts, and the method of directly deriving the relationship between courses In comparison, the derived curriculum relationship has high accuracy, high scalability, and can cover multiple fields.

Description

technical field [0001] The present invention relates to the fields of concept prerequisite relationship derivation, online education and knowledge map, and more specifically, relates to a method for constructing course map based on network embedding. Background technique [0002] With the rapid development of Internet technology, more and more traditional industries have begun to transform into Internet-based models. Among these industries, the education industry has also begun to develop vigorously with the convenience of the Internet. Famous educational platforms, including domestic MOOC, Netease Cloud Classroom, Chinese University MOOC, etc., as well as overseas Coursera, TED, iTunes U, MITOaenCourseware, etc. These websites cover knowledge in various subject areas. Through these online learning platforms, learners can learn courses from world-renowned universities or get guidance from outstanding practitioners in the industry at home or even at home. High-performance co...
