Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] In order to quantitatively evaluate the rumor risk, the specific implementation of the present invention proposes a rumor risk assessment method based on the network risk entropy difference. First, the rumor propagation model is established, and then the source of the rumor is determined, and then the propagation process is forwardly simulated from the source of the rumor, and finally The network entropy difference is defined in the propagation process to quantify the risk of rumors in real time. refer to figure 1 , the rumor risk assessment method proposed by the present invention includes the following steps S1 to S6:

[0022] Step S1, establishing a rumor propagation model based on the SIR model for the network platform to be evaluated.

[0023] The network platform described can be, for example, a social network platform with mains...

Abstract

The invention discloses a rumor risk assessment method based on A network risk entropy difference. The method comprises: S1, establishing an SIR model based rumor propagation model for a network platform to be assessed; S2, using the rumor source identification method to identify a rumor source and the propagation time on the basis of a network structure of the rumor propagation model; S3, simulating a forward propagation process of the rumor in the network structure to obtain the probability that each node in the network is in a different state at the current time; S4, calculating the maximumrisk entropy and the minimum risk entropy of the network at the current time according to the probability that each node is in a different state at the current time; S5, calculating the network riskentropy of the current time by using the maximum risk entropy and the minimum risk entropy of the network at the current time; and S6, calculating the network risk entropy difference according to thenetwork risk entropy at the current time and the previous time of the network, and assessing the potential risk caused by the rumors at the current time to the network platform according to the network risk entropy difference. The invention can quantitatively and accurately assess the risk caused by rumors to the network in real time.

Description

technical field [0001] The invention relates to the technical field of the Internet and information dissemination, in particular to a risk assessment method for network public opinion, network rumors or network false information based on network risk entropy difference. Background technique [0002] With the popularization of the Internet, more and more people begin to use the Internet for work, shopping, study and entertainment. According to the 40th "Statistical Report on Internet Development in China" by China Internet Network Information Center (CNNIC) on August 4, 2017, as of June 2017, the number of Internet users in China reached 751 million, accounting for one-fifth of the total number of Internet users in the world. one. The Internet has become a medium and platform for people to obtain information, express opinions, and communicate with each other every day. Such a convenient network platform has opened up a free channel for netizens to express their opinions and...
