Abstract

The invention provides a teaching video clip transaction system based on knowledge points. The teaching video clip transaction system comprises a data layer, a service logic layer and a service fusionlayer; the data layer comprises a teaching video file, a knowledge graph and an annotation index library; the service logic layer is connected with the data layer and comprises a video labeling module, a map establishing module, an index establishing module and a pricing module; the video annotation module is used for logically segmenting the teaching video file, realizing teaching video annotation based on three levels of knowledge points and generating knowledge point video clips; the map establishing module is used for establishing a knowledge map based on the knowledge point fragments; the index establishment module is used for establishing a retrieval relationship between the knowledge graph and the labeled index library; the pricing module is used for constructing a pricing model and automatically pricing the knowledge point video clip; and the service fusion layer comprises a terminal interface and is used for providing an access service for the terminal equipment. According tothe scheme, transaction cost can be reduced, circulation of teaching videos is facilitated, and learning is facilitated.

Description

technical field [0001] The invention relates to the technical field of teaching video segment trading, in particular to a teaching video segment trading system based on knowledge points. Background technique [0002] Teaching video is to make the knowledge, skills and other content that teachers want to impart to students into video form to assist modern multimedia teaching. That is to help teachers to more vividly and visually display the content that cannot be actually operated in the classroom, and at the same time truly record the teaching content, so that learners can learn repeatedly anytime and anywhere. It is an indispensable and important auxiliary tool in modern teaching. [0003] Existing teaching video trading is mainly based on the entire teaching video transaction. If learners need teaching video clips containing knowledge points, they must trade the entire teaching video. The transaction cost is high, which is not conducive to the circulation of teaching video...
