基于种子节点选择的重叠社区发现算法
发布时间:2019-01-03 08:07
【摘要】:针对目前从局部社区扩展成全局社区时有关算法的种子节点选择不合理的情形,提出了一种基于种子节点选择的重叠社区发现算法。首先根据影响力函数找出局部影响力最大的节点,由这些节点构成的种子集合较好地分布在整个网络中,然后以这些种子点构造初始社区,根据设定的吸引度函数选择性地添加节点来进行社区扩展。实验结果表明,该算法在真实网络上进行测试时能够有效地挖掘网络中的重叠社区。
[Abstract]:An overlapping community discovery algorithm based on seed node selection is proposed in view of the unreasonable selection of seed nodes when the algorithm is extended from a local community to a global community. Firstly, the nodes with the most local influence are found according to the influence function, and the seed set composed of these nodes is distributed well in the whole network, and then the initial community is constructed from these seed points. Selectively add nodes according to the set attractiveness function to extend the community. Experimental results show that the algorithm can effectively mine overlapping communities in real networks.
