Embodiment

[0063] Apply this method to the false information control of a social network, such as figure 2 As shown, there are a total of 26 user nodes in the network, and λ = 10, ε = 50%, that is, at least 10 detectors must be generated through clonal proliferation and mutation, and finally the coverage of false information will be reduced to below 50%. The affinity discrimination between the information forwarded by these user nodes and the target antigen information ω 0 The relationship is shown in Table 1 below:

[0066] Such as figure 1 As shown, explain: figure 1 The process description in is a summary of the following content, and the text may not be exactly the same, but the content is consistent. This method is the social network false information control method based on the cloning selection algorithm of the present invention, comprising the following steps:

Abstract

The invention discloses a social network false information control method based on a clonal selection algorithm. The method comprises the following steps that antigen and detectors are initialized; the detector selects nodes and calculates affinity; clonal selection is conducted; the detector is subjected to clonal proliferation; the detector is subjected to variation proliferation; the affinity of the detector subjected to variation proliferation is calculated again, and another detector is selected again; user nodes are selected again, and information similarity is calculated; assuming that Numt=Numc+Numv, when Numt>Lambada, the next step is carried out; the information coverage rate is calculated, and then the social network false information control process is completed. By means of the clonal selection information control method, varied network information can be effectively controlled; compared with a traditional social network false information control method, the efficiency and the accuracy of the method are both improved remarkably.

Description

technical field [0001] The invention relates to a method for controlling false information in a social network, in particular to a method for controlling false information in a social network based on a clone selection algorithm. Background technique [0002] Today, the development of social networks is in the ascendant. More than half of Internet users communicate and share information through social networks. However, while social networks bring us convenient information, their adverse effects cannot be ignored. In recent years, the proliferation of false information in social networks has become more and more serious, and governments at all levels, information supervision departments, and scientific researchers have also begun to pay more attention to it. Major online public opinion will not only affect people's normal life, but also bring a series of challenges to social stability and national security. It contains a lot of bad information such as violence, pornography,...
