Fuente: Wipo "BigData" The invention, which belongs to the technical field of data management, discloses an education big data management system comprising a video acquisition unit, an abstract extraction unit, a user information acquisition unit and a course matching unit. The video acquisition unit is used for acquiring a teaching video set and generating a teaching video key frame for each teaching video in the teaching video set; the abstract extraction unit is used for generating a teaching abstract for each teaching video key frame; the user information acquisition unit is used for acquiring a course search keyword set of a user; and the course matching unit is used for matching an optimal teaching video for the user according to the teaching abstract corresponding to each teaching video key frame and the course search keyword set of the user. The education big data management system determines the optimal teaching video by calculating the search weight sequence and the abstract weight sequence, and the comparison method is simple and easy to implement; the optimal teaching video is recommended for the user, and effective support is provided for online education big data management.
