Label Propagation Algorithm (LPA) is an efficient community detection method. Although it is simple and linear with a low time complexity, it suffers from the weaknesses of inaccuracy and instability. In this paper, we proposed a novel algorithm, namely, Core Expansion based Label Propagation Algorithm (CELPA). Specifically, we first extract several local core communities by computing similarity between nodes, and then expand these core communities to full communities. The proposed algorithm is evaluated on both real and artificial networks. Th...
