摘要: 正面信息在社交网络中传播的同时,还存在着大量消极负面信息在网络中扩散传播。针对抑制负面信息传播扩散的研究还相对较少的现状,提出了面向社交网络的负面影响最小化算法,当社交网络中出现消极负面信息且部分初始节点已被感染时,节点传播信息的行为取决于它与邻居节点的协调博弈,算法借助影响力最小化目标函数来寻找K个最优阻塞节点,最终通过阻塞K个未感染节点来最小化最终受感染节点的规模。实验结果表明:所提算法相较于3种基准算法能够更好地抑制负面影响扩散。

Abstract: While positive information is spreading in social networks, there is still a large amount of negative information spreading in the network. Aiming at the fact that there is few researches on suppressing the spread of negative information, a negative influence minimization algorithm for social networks is proposed. When negative information appears in social networks and some initial nodes are infected, the behavior of nodes propagating information depends on its coordination game with neighbor nodes. The objective function with minimal influence is used to find the K optimal blocking nodes, and finally the size of the final infected node is minimized by blocking K uninfected nodes. The experimental results show that the proposed algorithm can better suppress the negative influence diffusion than the three benchmark algorithms.

Key words: social networks, influence minimization, blocking nodes, negative influence
