Previous studies have used several models to investigate the mechanisms for growing and evolving real social networks. These models have been widely used to simulate large networks in many applications. In this paper, based on the evolutionary mechanisms of homophily and popularity, we propose a new generation model for growing and evolving social networks, namely, the Homophily-Popularity model. In this new model, new links are added, and old links are deleted based on the link probabilities between every node pair. The results of our simulation-based experimental studies provide evidence that the proposed model is capable of modelling a variety of real social networks.
先前的研究使用了几种模型来探究真实社交网络的增长和演化机制。这些模型已被广泛应用于许多领域中模拟大型网络。在本文中,基于相似性和流行度的演化机制,我们提出了一种新的社交网络增长和演化的生成模型,即相似性-流行度模型。在这个新模型中,新的链接是根据每个节点对之间的链接概率添加的,而旧的链接则被删除。我们基于模拟的实验研究结果提供了证据,证明所提出的模型能够对各种真实的社交网络进行建模。
