摘　　要：web网上的信息传播是社会复杂网络与信息复杂网络相互作用的结果。分析了web网和网民社会关系的结构特征,定义了信息价值时变函数,将网民基本行为归纳为读、写、评、传四类。基于多Agent建模方法建立web网信息传播仿真模型,用BA算法生成虚拟信息环境,采用WS模型刻画虚拟社会关系;定义了网民Agent的属性和行为规则,以及网民和网站的交互规则。设计了相关算法,实现了仿真模型,仿真结果表明该模型能够较好地模拟常态下的网络信息传播规律。Information diffusion on the worldwide web results from the interactions between social network and information network.The structural characteristic of Worldwide Web and users＇ social network was analyzed,the time-dependent function of information value was defined,and users＇ basic behavior was classified into read,write,review and propagate.An agent-based model of information diffusion on the web was built,the virtual information environment was generated by BA algorithm,and the virtual social network was depicted with WS algorithm.The property of agents,the behavior rules of users,and the interaction rules between user and web site were described.All the related algorithms were designed and the simulation model was implemented.The results show that some information diffusion rules in normal situation can be reproduced.
