The invention provides a data mining method and system applied to an environmental sanitation intelligent management platform, and the method comprises the steps: recognizing a video semantic feature sequence of each environmental sanitation monitoring video stream for training corresponding to an unbalanced abnormal event tag through an initial environmental sanitation abnormal event detection network, thereby determining the tag weight information of the unbalanced abnormal event tag; taking label weight information of the unbalanced abnormal event label as a network weight parameter of the unbalanced abnormal event label in the initial environmental sanitation abnormal event detection network, and then performing iteration updating to obtain a first target environmental sanitation abnormal event detection network; according to the method, the environmental sanitation monitoring video stream for training corresponding to the unbalanced abnormal event tag can be more strongly excited to the abnormal event ta
