基于成对约束标签传播的半监督重叠社区发现

Semi-Supervised Overlapping Community Finding based on Label Propagation with Pairwise Constraints

Elham Alghamdi, Derek Greene

摘要:

在复杂网络中检测社区的算法通常是无监督的,仅依赖于网络的结构。然而,这些方法通常无法发现反映数据中底层社区的有意义的分组,特别是当这些结构高度重叠时。提高这些算法的有用性的一种方法是通过合并附加的背景信息,其可以用作约束的来源以指导社区发现过程。在这项工作中,我们探索了半监督策略的潜力,以改善算法,在网络中找到重叠的社区。具体来说,我们提出了一种新的方法,标签传播的基础上,使用有限数量的成对约束,寻找社区。对合成和真实世界数据集的评估表明,这种方法在每个节点可能属于多个社区的情况下,有可能揭示有意义的社区结构。

英文摘要:

Algorithms for detecting communities in complex networks are generally unsupervised, relying solely on the structure of the network. However, these methods can often fail to uncover meaningful groupings that reflect the underlying communities in the data, particularly when those structures are highly overlapping. One way to improve the usefulness of these algorithms is by incorporating additional background information, which can be used as a source of constraints to direct the community detection process. In this work, we explore the potential of semi-supervised strategies to improve algorithms for finding overlapping communities in networks. Specifically, we propose a new method, based on label propagation, for finding communities using a limited number of pairwise constraints. Evaluations on synthetic and real-world datasets demonstrate the potential of this approach for uncovering meaningful community structures in cases where each node can potentially belong to more than one community.
