摘要： 为研究聚合群体中关系强度对观点采纳的作用机制,基于关系强度理论,设计一种识别关系强度的方法。采用单源感染的易感者-染病者-免疫者传播模型,以λ=βα为节点间的传染概率,分析聚合群体中关系强度对观点采纳的作用机制。实验结果表明,观点权威性的加强与好友推荐策略有利于提高观点采纳广度和速度,对提升聚合群体中的广告投放效果与加速信息扩散以及抑制谣言传播都具有一定实用价值。

Abstract: In order to study how relationship strength affects the adoption of viewpoint in aggregation groups,this paper designs a new method which is based on the relationship strength theory.It uses the single source of infection with Susceptible-Infected-Recovered (SIR) model,assuming the infection rate is λ=βα,to analyse how relationship strength affects the adoption of viewpoint.Experimental results show that strengthening the authority of viewpoint and friend rewmmendation strategies are conducive to enhancing the probability and velocity of the adoption of viewpoint.It has a certain practical value to enhance advertising effectiveness on aggregation groups,accelerate information diffusion and inhibit the spreading of rumors.

Key words: aggregation groups, relationship strength, Susceptible-Infected-Recovered(SIR) model, effect spreading, relationship network
