The Research For Online Social Network Spreading Dynamic Process And Visualization Method

Online social networks as one of the main social tool in today’s society, its complex information dissemination process and time-varing of the internal structure making it the hotspot in recent years. In view of the existing research on its real internal spreading process is insufficient,from the spreading dynamic model and information visualization combined angle,this paper do the exploratory research by using the theory and practical approach.In order to further investigate the effect of its transmission dynamics of the process of information dissemination, in theory, this thesis applied the communication theory to analyse and redefined the process for the information dissemination on the online social network,present the information dissemination pattern which has cut-off characteristics and dispersion characteristics, adopt an hierarchical progressive approach to structure properties and global properties of network,and do the explained and validation studies.In practical application, this paper draw on traditional dynamic simulation model--SIR model, combined with the online social network communication mode features to built a spreading dynamic model of online social network--SCIRK model, the model considers the node’s own property of communication process in its acceptance of subjective, the internal coupling is proposed based on different roles in controlling the spread of the information spreading process in the presence of a network, from a practical point of view,analyse the role of model for the actual control of information dissemination, and discuss the interactive strategy and immunization strategy between nodes within the model. with the simulation analysis on real network to verify the applicability and effectiveness of the transmission dynamics model.To facilitate further study of the spread of the dynamic process of online social networks, Based on Java Swing, a visualization tool was designed, which is designed to reduce the complexity of the study on online social network spreading dynamic process,and exhibit the process of information spreading process and communication range more clearly and intuitive,and autonomic defined the formula of node importance ranking, analyzes the impact of the spreading results with selection method for key nodes in the spreading dynamic process, hope to provide the reference for subsequent research work.
