复杂网络中基于边界节点的社区发现

Community detection using boundary nodes in complex networks

Mursel Tasgin, Haluk O. Bingol

摘要:

我们提出了一个新的本地社区检测算法,发现社区之间的边界线,使用边界节点。我们的方法执行标签传播社区检测,其中节点决定他们的标签的基础上表现出最大的“效益分数”的近邻作为吸引他们的社区。我们尝试了不同的指标,发现使用共同邻居的数量作为收益分数可以为社区结构做出更好的决策。该算法具有局部逼近的特点,在标签传播迭代过程中只关注边界节点,消除了不必要的步骤,缩短了整体执行时间。它保留了小社区以及大社区,并且在识别社区的质量方面优于其他算法,特别是当社区结构很微妙时。该算法具有分布式的性质,可以在大型网络上以并行的方式使用。

英文摘要:

We propose a new local community detection algorithm that finds communities by identifying borderlines between them using boundary nodes. Our method performs label propagation for community detection, where nodes decide their labels based on the largest "benefit score" exhibited by their immediate neighbors as an attractor to their communities. We try different metrics and find that using the number of common neighbors as benefit scores leads to better decisions for community structure. The proposed algorithm has a local approach and focuses only on boundary nodes during iterations of label propagation, which eliminates unnecessary steps and shortens the overall execution time. It preserves small communities as well as big ones and can outperform other algorithms in terms of the quality of the identified communities, especially when the community structure is subtle. The algorithm has a distributed nature and can be used on large networks in a parallel fashion.
