复杂网络上知识流动的小世界现象

Small World Phenomenon of Knowledge Flowing in Complex Networks

针对知识网络相关研究的结构主义倾向,基于非正式关系具有结构/关系二相性的认识,利用多主体建模与仿真方法,针对保持载体网络复杂网络结构特性不变的基础上,对改变网络关系强度宏观分布是否能够进一步提高知识流动效率问题进行了研究。结果表明,改变网络关系强度宏观分布不但能提高网络知识流动效率,而且当关系强度变动概率较小时存在知识流动的小世界现象。对此现象的分析表明,其具有普遍性。

In allusion to the on related research structuralism tendency of networks,and based on the understanding that the structure-relation duality is the inherence characteristic of informal relation,this paper studies the knowledge efficiency of small world networks under different probabilities of relation strength changing.The results show that,when the probability of relation strength change increases,the knowledge efficiency of small world networks can be enhanced apparently;especially,when the probability of relation strength change falls into a proper interval,the small world phenomenon of knowledge flowing appears.Further analysis shows the phenomenon is universal.
