DKGV: A Dynamic Knowledge Graph Visualization Method Based on Force-Directed Layout

The dynamic knowledge graph is a data structure that adds temporal information to the nodes and edges of a traditional knowledge graph. It describes the changing processes of entities and relationships over time, thereby enriching and updating the expression of knowledge. The dynamic knowledge graph possesses characteristics such as time and labels; it is not only a knowledge graph but also a type of dynamic graph containing heterogeneous information.
