近年来,许多关于社区发现的优秀算法被提出并取得了较好的社区划分效果。但是到目前为止,没有任何一种算法能够同时在时间复杂度和准确度方面取得较好的表现。现实网络中往往存在一些有利于指导社区发现的标签信息,如must-link信息、cannot-link信息等。因此提出基于少量标签信息传播、拓扑结构的半监督社区发现算法S_LPA,分别在karate网络、dolphins网络、LFR基准网络上进行测试。实验结果表明,该算法S_LPA时间复杂度为O(m),相对其它算法,S_LPA在karate网络和dolphins网络的NMI值高于CNM、InfoMap、LPA算法,在LRF网络上准确度高出约20%;提高参数u后,S_LPA算法可识别其它算法不能识别的社区结构。  相似文献
