Research Of Dissemination Control Mechanism In Social Network

With the popularity and development of social network, the scale of social network isgetting more and huger, and it is extending farther and farther. The way people communicatewith each other has shift from the real social circle to the Internet gradually. Because of busywork and study, many people prefer contacting with each other through social networking site.Social network has its own characteristics such as familiarly user contact and fast informationsharing which provide Internet users with the convenience of communication but also providea lot of sex, opinion, rumors and other negative information with a convenient route oftransmission. The information in social network spread fast, and it transfers from one user toadjacent users by fan-shaped, so that the affected areas were growing doubled. Although thepeople of domestic and foreign have also done a lot of related work about dissemination ofinformation in the network and control, and achieved certain results, but because of shot timeof occurrence of social network, the spread of social networks in control has not been givensufficient attention. In the above background, this paper has done research on the socialnetwork of the dissemination of information.Before the study of information control in social networks, these papers analyzed thecharacteristics of information dissemination and build the dissemination model of information.The current information dissemination model in social network is mainly through the process,in which the virus SIR model is adapted for the SIR information dissemination model ofsocial network. In the process of building social network information dissemination model,there were along the line of thought, analyzing the SIR information dissemination model ofsocial network, and building the SEIR information dissemination model.In the aspect of control algorithms, there are a large number of communities in a socialnetwork, which has a feature that information spread fast within close connection in thecommunity and it is weak connection among communities, so the spread is slow relatively.According to the characteristics of this information above, this paper developed acommunity-based control algorithm. According to the division of community in the socialnetwork, algorithm controls the spread of information among the communities So thatinformation can only be spread within the community and can not spread to the entirenetwork. Therefore, information dissemination is effective controlled.
