Embodiment Construction
[0048] The present invention will be further described below in conjunction with the accompanying drawings.
[0049] refer to figure 1 , realize the concrete steps of the present invention as follows:
[0050] Step 1, build an adjacency matrix.
[0051] Input the heterogeneous social network data to be detected. The heterogeneous social network used in the embodiment of the present invention is such as figure 2 as shown, figure 2 is a user-item heterogeneous network.
[0052] Count the number of node types and the number of each type of nodes in the heterogeneous social network data respectively. There are two types of nodes in this network, that is, the number of node categories k=2, where the first type of nodes represent users, and the second type of nodes represent commodities, namely figure 2 The square in represents the first type of node, there are 10 in total, namely n 1 =10, the circle represents the second type of nodes, there are 10 in total, namely n 2 =...
