Key figure mining method and system based on communication network data analysis

The invention provides a key figure mining method and system based on communication network data analysis. The method comprises the steps that 1, communication records are acquired and preprocessed, a directed weighted communication network is constructed according to the preprocessed communication records, an authorized adjacency matrix is constructed according to the directed weighted communication network, and an authority value and a hub value are calculated; 2, a new authority value and a new hub value are calculated according to the authority value and the weight of two node link edges in the directed weighted communication network; and 3, an abnormal feature parameter alpha is set, a final authority value is calculated according to the new authority value and the new hub value, and maximum-minimum normalization is performed on the final authority value to obtain a key figure. Through the key figure mining method and system, information of the key figure in the communication network can be acquired quic
