Method and device for constructing clouded network alarm root cause relationship tree model

According to the method and the device for constructing the alarm root cause relationship tree model of the clouded network provided by the embodiment of the invention, the corresponding classification weight value of the first alarm tree model mined from the traditional network is determined according to different classification categories through machine learning, and in the network to be modeled, the second alarm data obtained by mining is used as the alarm root cause relationship tree of the clouded network. The same machine learning is adopted to perform modeling by using the classification weight value obtained by the traditional network to obtain the second alarm tree model, so that the establishment of the alarm root cause relationship tree model of the new network is realized on the basis of the traditional network, and meanwhile, the establishment process of the model becomes more flexible and accurate by adopting a machine learning mode. 根据本发明实施例提供的一种构造云化网络告警根因关系树模型方法和装置，通过机器学习将从传统网络中挖掘出来的第一告警树模型按照
