Abstract

The invention discloses an online course recommendation method, which comprises the following steps: establishing entity relation models of courses respectively about students, schools and teachers by taking the courses, the students, the schools and the teachers as nodes in advance; according to the established entity relationship model, obtaining course association node information associated with a target student of the course to be recommended; calculating a multi-hop information propagation vector of the target student and each course association node, and taking the multi-hop information propagation vector as a representation vector of the target student and the course association node; according to the representation vector of the target student and the representation vector of each course association node, completing course recommendation for the target student. The invention can comprehensively consider the curriculums recommended to the students by utilizing the entity relationships between the curriculums and the students, between the curriculums and the schools and between the curriculums and the teachers, can comprehensively utilize the relationships among multiple entities, improves the accuracy of curriculum recommendation, and meanwhile, after each round of recommendation, the system updates the recommendation model by utilizing the feedback of the students, so that the real-time performance of recommendation is ensured.
