双有限异质社交网络仿真建模及实证分析

Double Limited and Heterogeneous Social Network:A Simulation and Empirical Study

提出了一种双有限异质社交网络结构,即网络规模有限性、节点出/入度有限性以及网络节点属性的异质性.仿真结果及实证分析表明,与小世界网络、无标度网络等相比,双有限异质社交网络模型可以更好地模拟实际社交网络,不仅其网络整体结构兼具小世界特性和无标度特性,在微观上还可以真实反映出不同属性类型的节点在网络中的影响力和控制力.

A double limited and heterogeneous social network was proposed to analyze the structure of so- cial network in China, namely the limited size of the network and in-degree and out-degree of the nodes, and the heterogeneous attributes of the nodes. Compared with the small-world and scale-free network, the double limited and heterogeneous social network can better simulates the real social network. It not only has the overall structure characteristics of the small-world and scale-free network, but also reflects the in- fluence and control of the different types of nodes in the social network at the micro level.
