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. Based on the cross-platform network topology constructed, the directed graph of a single platform is classified by using the position centrality of the node and the network constraint value, and the cross-platform node is used to classify the directed graph. Classify each node in the cross-platform directed graph according to the time similarity of the node, obtain the propagation probability of each node according to the classification of the node, and establish the information propagation process across social networks. The present invention extends the information dissemination process to multiple social networks, and classifies user nodes according to user heterogeneity, thereby establishing a cross-network information dissemination process, making it more in line with the actual information diffusion characteristics, and providing public opinion monitoring and control , product promotion, personalized recommendation and other applications provide the basis.

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...
