Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings.

[0044] refer to figure 1 , to further describe in detail the specific steps for realizing the present invention.

[0045] Step 1, build a cross-platform network topology:

[0046] In the first step, in the two known social platforms with different functions, each user in each social platform is regarded as a node in the directed graph, and the relationship between users is regarded as the relationship between nodes in the directed graph. edges, combine all the nodes corresponding to each social platform and the edges between nodes into a directed graph, and obtain the directed graph G of a single platform 1 and G 2 .

[0047] In the second step, the single platform directed graph G 1 and G 2 Two nodes of the same user form a cross-platform node pair, and an edge is established between the two nodes of each cross-platform node pair, and all cross-platform node pai...

Abstract

The invention discloses an information dissemination method based on a cross-social network. The method is based on a constructed cross-platform network topology. Classifying the single platform directed graph by utilizing the position centrality of the nodes and the network constraint value, classifying each node in the cross-platform directed graph by utilizing the time similarity of the cross-platform node pair, obtaining the propagation probability of each node according to the classification of the nodes, and establishing an information propagation process of the cross-social network. According to the method, the information spreading process is expanded to a plurality of social networks, and the user nodes are classified according to the heterogeneity of the users, so that the cross-network information spreading process is established, the actual information spreading characteristics are better met, and a basis is provided for public opinion monitoring and control, product propaganda, personalized recommendation and other applications.

Description

technical field [0001] The invention belongs to the technical field of communication, and further relates to an information dissemination method based on a cross-social network in the technical field of network information dissemination. The invention can be used for simulating the information dissemination process in the social network and predicting the information dissemination range under the environment of the cross social network. Background technique [0002] Due to the diversity of online platforms, network users may be active on two or more social platforms at the same time, and users' information acquisition and dissemination can also cross network boundaries. Therefore, the Internet is a complex network formed by the cross-coupling of many networks with different properties and characteristics. A single network layer is only a subset of it. This coupling exists between multiple online social networks. Therefore, it is of practical significance to study the inform...
