Abnormal graph mining method and device, storage medium and electronic equipment

The invention discloses an abnormal graph mining method and device, a storage medium and electronic equipment. In the abnormal graph mining method provided by the specification, a sample service graph is acquired, abnormal nodes in the sample service graph are determined as black nodes, and nodes without abnormity are determined as white nodes; determining a black sample sub-graph taking a black node as a central node and a white sample sub-graph taking a white node as a central node in the sample service graph; for each graph mode, determining the black support degree of the graph mode according to the number of black sample sub-graphs isomorphic with the graph mode; according to the node features in the graph mode and the node features in the white sample sub-graphs, matching the graph mode with the white sample sub-graphs to obtain the number of the white sample sub-graphs matched with the graph mode, and determining the white support degree of the graph mode according to the number of the white sample sub
