[0046] In order to further illustrate the present invention, now in conjunction with the attached figure 2 The present invention is described in detail. Specific steps are as follows:
[0047] Step 1: Obtain network topology and build node adjacency matrix
[0048] First, read the link relationship between network nodes from the node link relationship file of the data set. The link relationship is directional, and an adjacency matrix is constructed. The value in the matrix is 1, which means that the node corresponding to the row subscript exists to point to the column subscript corresponding A node of , a value of 0 indicates that the corresponding node does not have a link relationship. Each row of the adjacency matrix represents the out-link neighbor set of the node corresponding to the row subscript, and the column represents the in-link neighbor set of the node corresponding to the column subscript.
[0049] Step 2: Calculate the importance of nodes in the global t...
