With the rapid development of online education, the number of teaching resources on the Internet has also shown a rapid growth trend. However, the current online learning platform has many problems such as duplication of teaching resources and people’s difficulty in distinguishing and selecting them. As a result, it is difficult for learners to choose suitable resources to construct their own learning paths.The paper proposes a knowledge network construction method for learning path recommendation. Firstly, a corresponding domain knowledge network is constructed through social annotation of each learning object’s pre-knowledge and post-knowledge. Secondly, the Floyd-Warshall algorithm is used to calculate the shortest path between any two knowledge points in the domain knowledge network, so as to provide a basis for the learning path recommendation.
