METHOD FOR CONSTRUCTING CLOUD NETWORK ALARM ROOT CAUSE RELATIONAL TREE MODEL, DEVICE, AND STORAGE MEDIUM

A method for constructing a cloud network alarm root cause relational tree model, a device, and a storage medium. The method comprises: mining, according to a frequent itemset, first alarm data of a traditional network to obtain a first alarm tree model, and performing, by using a traditional expert knowledge database as a label, feature extraction on the first alarm tree model to obtain a first feature parameter; customizing, according to a pre-determined classification rule, classification types, and determining, by means of machine learning, a classification weight value corresponding to each of the classification types in the first alarm tree model; and mining, according to the frequent itemset, second alarm data of a network awaiting model-building, and performing, by using machine learning and the classification weight value, model-building on the second alarm data to obtain a second alarm tree model, the second alarm data being root-cause relation data.
