Abstract: Focusing on issues of incomplete user information and inaccurate recommendations in current vocational education course recommendation methods, this paper first constructs a knowledge graph (KG) for vocational education. On this basis, a novel negative sampling approach is employed to enhance the KG representation model TransH (EOTransH), and different weights are given to negative samples assigned different scores contribute to full model training. Then, a bipartite graph of courses and users is constructed, and KG embedding is built through the joint user entity neighbourhood information. Furthermore, higher-order connectivity information between users and courses is mined through attention-based propagation. Finally, an attention network is built in the output prediction layer to explore user preference features. Experimental outcome on the MOOCCourse and MOOCCube datasets indicate that the proposed approach improves F1 by at least 2.05%, 4.09%, effectively solving the problem of inaccurate recommendations.
