Abstract: Methods, devices, and computer-readable media of task execution based on a knowledge graph obtained by entity alignment are provided. In one aspect, a method includes: obtaining a knowledge graph pair including a first knowledge graph and a second knowledge graph, selecting a target entity by filtering entities in the first knowledge graph, determining a centrality and an uncertainty of the target entity based on the target entity, an entity corresponding to a neighboring node, and entities in the second knowledge graph, constructing a sample entity pair based on the centrality and the uncertainty of the target entity, training a to-be-trained entity alignment model using the sample entity pair, performing entity alignment on to-be-aligned knowledge graphs according to the trained entity alignment model to obtain a merged knowledge graph, and executing a target task based on the merged knowledge graph.
