基于重叠用户的多社交网络社区发现

Community Detection Across Multiple Social Networks based on Overlapping Users

Ziqing Zhu, Tao Zhou, Chenghao Jia, Weijia Liu, Jiuxin Cao

摘要:

随着互联网技术的飞速发展,在线社交网络(OSNs)得到了快速发展,并日益流行。同时,跨多个社交网络的研究也越来越受到研究者的关注,而社区发现是跨OSN的网络安全问题的重要研究内容,主要用于分析用户行为和发现异常社区。提出了一种基于用户重叠的多社交网络社区发现方法。首先定义了重叠用户的概念,然后设计了一种基于社会相关性的重叠用户存根社区发现算法CMN NMF。在此基础上,通过添加具有较强相似性的用户,扩展不同社交网络中的存根社区,最终挖掘出不同的社区。在真实数据集上的实验结果表明了该方法的有效性。

英文摘要:

With the rapid development of Internet technology, online social networks (OSNs) have got fast development and become increasingly popular. Meanwhile, the research works across multiple social networks attract more and more attention from researchers, and community detection is an important one across OSNs for online security problems, such as the user behavior analysis and abnormal community discovery. In this paper, a community detection method is proposed across multiple social networks based on overlapping users. First, the concept of overlapping users is defined, then an algorithm CMN NMF is designed to discover the stub communities from overlapping users based on the social relevance. After that, we extend each stub community in different social networks by adding the users with strong similarity, and in the end different communities are excavated out across networks. Experimental results show the advantage on effectiveness of our method over other methods under real data sets.
