If the vertex set of a graph can be partitioned into two disjoint nonempty sets V_(1) and V_(2), every vertex in V_(1) connects every vertex in V_(2) and there is no edge in V_(1) and V_(2), then we call this graph is a complete bipartite graph. If V_(1) contains m elements and V_(2) contains n elements, then we denote this complete bipartite graph K_.

Most of community detection algorithms are used in dealing with unipartite networks, and there are few algorithms designed for detecting communities in bipartite networks, and these algorithms have some weaknesses respectively. For example, the community detection algorithm proposed by Guimera can not utilize weight information of a bipartite network; the algorithm proposed by Barber can not deal with the complex mapping situation of communities in bipartite network.

目前社团检测算法大多用于处理单元网络，而专门用于处理二分网络的社团检测算法不多，而且这些算法都存在着各自的不足之处，如 Guimera 所提的二分图社团检测算法无法处理边含权重信息的二分网络； Barber 所提的社团检测算法无法处理二分网络中具有复杂社团对应关系的情况。
