摘要
众多结构主义研究指出当网络呈现小世界特性时非正式知识网络效率最高。基于非正式关系本质上具有结构/关系二相性的认识,通过仿真模型研究了不同关系强度变动概率下小世界网络的知识效率。结果表明,随着关系强度变动概率的增加,均衡状态下网络知识流动效率得到极大提高;特别地,当强度变动概率处于一个小概率区间时,会出现网络知识流动的小世界现象。
Many studies of structuralism find that the knowledge efficiency is high when networks show characteristics of small world. Based on the understanding that the structure - relation duality is the inherence characteristic of informal relation, we study the knowledge efficiency of small world networks under different probabilities of relation strength changing. The results show that, when the probability of relation strength changing increases, the knowledge efficiency of small world networks can be promoted apparently ; especially, when the probability of relation strength changing falls into a proper interval, the small world phenomenon of knowledge flowing appears.
