摘要

当前演化模型研究中，主要是单一话题在网络中的传播，较少考虑多话题之间的相互影响因素。在SIR 模型的基础上提出了基于干扰相似度的多话题演化模型，该模型中的干扰是通过话题相似度对传播概率的影响来表征的。仿真结果表明，在临界值以内，正负两种趋向的话题相似度分别对话题演化的进程起到加强或阻碍作用，作用程度随着被干扰节点的度而变化，分别表现为正向相似度下的演化一致性和负向相似度下的演化分离性。超过临界值时，加强或阻碍作用均趋于饱和。

Abstract

The current researches of evolution model mainly focus on the spread of the individual topics

rarely considering the influential factors between multiple topics.A new topic evolution model was proposed by considering the interference among topics based on SIR model

which characterized by the influence of the similarity of the topic on the probability of propagation.The experimental results show that within the critical value

the similarity degree of positive and negative trends enhance or hinder the process of topic evolution

and the degree of action varies with the degree of interference nodes

which is expressed as evolutionary consistency under positive similarity and the evolutionary separability under negative similarity.When the critical value is exceeded

the effect of strengthening or hindering tends to saturation.
