【摘要】 针对非正式知识网络上的知识流动小世界现象,利用多主体建模与仿真方法,基于经典WS小世界网络建立知识流动模型,研究了知识流动小世界现象的发生机理。结果表明,知识流动小世界现象的内在机理为网络宏观关系强度分布呈现指数衰减;网络知识流动效率对于网络宏观关系强度分布具有高度敏感性;网络平均关系强度均值的不同会影响网络关系强度分布的演化速度,但不影响其演化模式。更多还原

【Abstract】 Aiming at the phenomenon of small world of knowledge flowing on informal knowledge networks,using the method of MAS,building a knowledge flowing model based on the classic WS small world model,we studies the occurrence mechanism of the phenomenon.The results show that the exponential decay of relation strength is necessary for the phenomenon,the efficiency of knowledge flowing in the networks is seriously sensitive to the distribution of relation strength and the mean value of relation strength on networks will influence the evolutionary speed but not influence the evolutionary pattern.更多还原
