摘要
采用元胞自动机(CA)理论研究因特网舆情传播,设计了一个舆情传播元胞自动机模型结构,包括元胞状态取值、元胞空间和邻域。针对互联网元胞状态转换提出了考虑元胞坚定性的多数规则计算公式和元胞移动遍历算法。在讨论仿真结果时定义了倾向强度、倾向聚集度、元胞峰值和元胞倾向众值等四个参数,分别对不同坚定性和固定/移动元胞状态计算的迭代结果讨论其不同的演变过程、形态和意义,提出特别需要关注具有坚定性特点的元胞移动遍历的舆情传播过程,它们更加接近因特网网络舆情的真实传播过程。仿真结果说明了该方法和模型的有效性和合理性。
A structure of Cellular Automata（CA）for dissemination of network public sentiment was designed,which was composed of selection of cellular state data,lattice space,and neighbor.Then a majority transform rule modified with persistency of cell was proposed by a new equation as well as an algorithm of considering the information influence of cell movement traversing lattice space.A serial simulation was put into experiment to evaluate above model.Four parameters including inclination intensity,inclination focusing degree,cell number peak,and ratio of cell number in different inclination class were designed before discussion.The iteration calculation showed the results had different transit procedure,patterns and meaning respectively followed by a cell with variable persistency and in static or moving condition.Finally it suggested that the cell moving traversing lattice with persistency should be given special concern as it conformed to Internet reality.The simulation results prove that the proposed method is valid and effective.
