As a new task of expertise retrieval, finding research communities for scientific guidance and research cooperation has become more and more important. However, the existing community discovery algorithms only consider graph structure, without considering the context, such as knowledge characteristics. Therefore, detecting research community cannot be simply addressed by direct application of existing methods. In this paper, we propose a hierarchical discovery strategy which rapidly locates the core of the research community, and then incrementally extends the community. Especially, as expanding local community, it selects a node considering both its connection strength and expertise divergence to the candidate community, to prevent intellectually irrelevant nodes to spill-in to the current community. The experiments on ACL Anthology Network show our method is effective.
