This invention discloses an event prediction method and apparatus based on subgraph segmentation and entity relationship model. It transforms an academic knowledge graph into a sequence of temporal historical subgraphs. Segmentation operations determine the segmentation points of the temporal historical subgraph sequence and the number of segments corresponding to different times. The number of continuous segments is also determined. A DQN network is used to perform secondary path search through target operations to obtain the final search path. The entity in the last node is the object to be predicted. This invention achieves this by segmenting the temporal historical subgraph sequence to give the input data a focus, enabling better selection of answer nodes. Secondly, the use of a DQN network better considers the intrinsic connections between entities and relationships. Finally, the global nature of convolutional neural networks captures the global features of the search path, significantly improving prediction accuracy.
