[0032] A construction method of a personalized learning feature model based on knowledge graphs. During the construction of knowledge graphs, two types of entities are mainly targeted: knowledge points and learning resources. The relationship between knowledge points mainly focuses on the sequence of learning; the relationship between learning resources and knowledge points mainly focuses on their "belonging" relationship; the relationship between learning resources mainly focuses on their hierarchical relationship. For the convenience of discussion, we call the space composed of knowledge points and their relationships knowledge network space; the space composed of learning resources and their relationships is called learning resource space.
[0033] A directed acyclic graph is used to represent the knowledge network space, such as figure 1 shown. Each node in the graph represents a knowledge point. There is a predecessor-sequence relationship between knowledge points, whic...
