Embodiment 1

[0049] A method of controlling the dissemination of information in online social networks, such as figure 1 shown, including:

[0050] Step S101, constructing an information dissemination network, the information dissemination network including nodes, information circulation direction and information dissemination probability;

[0051] The information dissemination network is constructed based on the user relationship chain of the online social network and the user's historical information dissemination behavior, including nodes, information circulation direction and information dissemination probability;

[0052] Such as figure 2 As shown, the information dissemination control scheme in the prior art mainly calculates the user's topological characteristics according to the social network where the user is located, and uses this as the measurement standard to select the top-ranked users as immune control users, without considering the difference between nodes , and there is n...

Embodiment 2

[0081] A device for controlling the dissemination of information in online social networks, such as Figure 5 shown, including:

[0082] The overall structure of the device is as Figure 5 As shown, it includes three parts: data acquisition application, data cleaning and data application. The core of the device is the data application part, which can be subdivided into information dissemination network construction module 203, offline learning module 204, online prediction module 205 and online experiment module 206.

[0083] An information dissemination network construction module 203, configured to construct an information dissemination network, the information dissemination network including nodes, information flow direction and information dissemination probability;

[0084] The offline learning module 204 includes an offline feature calculation submodule and an offline model learning submodule.

[0085] The offline feature calculation sub-module mainly uses user relati...

Embodiment 3

[0100] A method of controlling the dissemination of information in online social networks, such as Figure 6 shown, including:

[0101] Step S301, constructing an information dissemination network, the information dissemination network including nodes, information circulation direction and information dissemination probability;

[0102] The information dissemination network is constructed based on the user relationship chain of the online social network and the user's historical information dissemination behavior, including nodes, information circulation direction and information dissemination probability;

[0103] Such as figure 2 As shown, the information dissemination control scheme in the prior art mainly calculates the user's topological characteristics according to the social network where the user is located, and uses this as the measurement standard to select the top-ranked users as immune control users, without considering the difference between nodes , and there i...

Abstract

The present invention proposes a method, device and terminal for controlling online social network information dissemination, including: constructing an information dissemination network, calculating offline features of nodes, extracting training samples from offline features, and training pre-built nodes through machine learning to disseminate influence Force prediction model, calculate the online features of nodes, provide offline features and online features as input to the node propagation influence prediction model, the node propagation influence prediction model makes predictions and output the node propagation influence prediction value; combined with the node propagation of the current node Influence prediction value and information of other nodes within the specified time window size determine whether to control the current node. The invention can adapt to a dynamically changing information dissemination network, and solves the problem of inaccurate node selection for information dissemination control in an online social network.

Description

technical field [0001] The present invention relates to network technology, in particular to a method, device and terminal for controlling the dissemination of online social network information. Background technique [0002] Information dissemination control in online social networks is aimed at controlling the dissemination of illegal and false information such as rumors, pornography, gambling, and drugs in social networks, and providing users with a good network environment. Information such as information dissemination behavior, to evaluate the importance of users in information dissemination. Therefore, before the outbreak of illegal and false information, the large-scale dissemination of information can be avoided by conducting information immune control on users with high influence. [0003] Most of the information dissemination control schemes in the prior art are based on the social network where the user is located, using a static network topology feature as the ev...
