A local community detection algorithm based on influential nodes set(IN-LCD)is proposed to focus the problems that the local community detection in large-scale network is sensitive to the position of source nodes and the topology information is difficult to effectively use. A local influence index for nodes is defined
and a subset of influential nodes near the source node is calculated and constructed with the index. Then
the continuous expansion of the community is realized from the subset
and the whole local community is constructed through the calculation of the similarity index between nodes and community. The method uses the most influential nodes set to expand the community and effectively overcomes the sensitive problem of local community detection to initial node position. Experiments on real and artificial network data sets and a comparison with an existing local community detection method show that the recognition performance of the proposed IN-LCD is improved by 5.3%.
