基于相似性的多原型社区发现方法

A similarity-based community detection method with multiple prototype representation

Kuang Zhou, Arnaud Martin, Quan Pan

摘要:

社区对于理解社交网络中的图结构具有重要意义。一些现有的社区发现算法使用单个原型来表示每个组。在实际应用中,这可能无法充分模拟不同类型的社区,因此限制了社交网络上的聚类性能。针对这一问题,提出了一种基于相似性的多原型社区发现方法。在SMP中,每个社区中的顶点具有不同的权重来描述它们的代表性程度。这种机制使每个社区能够由多个节点表示。节点的中心性用于计算原型权重,而相似性用于指导我们划分图。计算机生成的和真实世界的网络上的实验结果清楚地表明,SMP执行良好的检测社区。此外,与现有的社区发现模型相比,该方法借助原型权值,能够提供更丰富的社区内部结构信息。

英文摘要:

Communities are of great importance for understanding graph structures in social networks. Some existing community detection algorithms use a single prototype to represent each group. In real applications, this may not adequately model the different types of communities and hence limits the clustering performance on social networks. To address this problem, a Similarity-based Multi-Prototype (SMP) community detection approach is proposed in this paper. In SMP, vertices in each community carry various weights to describe their degree of representativeness. This mechanism enables each community to be represented by more than one node. The centrality of nodes is used to calculate prototype weights, while similarity is utilized to guide us to partitioning the graph. Experimental results on computer generated and real-world networks clearly show that SMP performs well for detecting communities. Moreover, the method could provide richer information for the inner structure of the detected communities with the help of prototype weights compared with the existing community detection models.
