Embodiment Construction

[0053] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0054] see figure 1 , the specific steps of the present invention to construct a cross-media dynamic knowledge map are:

[0055] Step 1. Acquisition of knowledge in the subject area; use Python tools to crawl the required course-related information in multiple channels, including text, images, videos, exercises, PPT, etc.

[0056] Step 2, data cleaning and preprocessing; manually clean the crawled data to ensure the accuracy of the data.

[0057] Step 3: Labeling of datasets; for text data, the BIO method is used for manual labeling.

[0058] The BIO labeling method refers to labeling each element in the data set as "B-X", "I-X" or "O". Among them, "B-X" indicates that the segment where this element is located belongs to type X and this element is at the beginning of this segment, "I-X" indicates that the segment where this element is located belongs to ty...

Abstract

The invention discloses a teaching method and system based on cross-media dynamic knowledge graph. The method comprises the following steps of constructing the cross-media dynamic knowledge graph; storing entity related information in the knowledge graph, and returning attribute values corresponding to entities through subject knowledge questions and answers; obtaining feedback information of students and knowledge points, calculating the knowledge point recommendation degree and the learning resource recommendation value score, and therefore, constructing a knowledge point recommendation listand a learning resource recommendation list and returning the lists to learners; constructing a course knowledge card; recommending friends, and recommending other users with similar learning progress and learning conditions to the current user. The teaching system comprises a data layer, a data analysis layer, an application layer and a user layer. The teaching method can be realized through a computer-readable storage medium. The problem that in the prior art, a teaching scheme cannot be formulated in a targeted mode according to learning characteristics is solved, the individualized teaching can be achieved, and the teaching level is effectively improved.

Description

technical field [0001] The invention belongs to the field of artificial intelligence and education informatization, and specifically relates to a teaching method and system based on a cross-media dynamic knowledge graph. On the basis of a cross-media dynamic knowledge graph, artificial intelligence technology is used to realize subject knowledge question answering and intelligent learning resource recommendation , course knowledge card, friend recommendation and other functions, so as to improve the teaching level. Background technique [0002] With the rapid development of technologies such as artificial intelligence and deep learning, education informatization has entered the 2.0 era characterized by artificial intelligence technology. The smart education model supported by artificial intelligence and other information technologies has become a trend in the development of educational informatization, and has also become a hot research direction in academia. As an importan...
