Identifying the nodes with largest spreading influence is of significance for information diffusion, product exposure and contagious disease detection. In this letter, based on the local structural similarity, we present a method (LSS) to identify the multiple influential spreaders. Firstly, we choose the node with the largest degree as the first spreader. Then the new spreaders would be selected if they belong to the first-or second-order-neighbor node set of the spreaders and their local structural similarities with other spreaders are smaller than the threshold parameter r. Comparing with the susceptible-infected-recovered model, the experimental results for four empirical networks show that the spreading influences of spreaders selected by the local structural similarity method are larger than that of the color method, the degree, betweenness and closeness centralities. The further experimental results for the Barabàsi-Albert and random networks show that the LSS method could identify the multiple influential spreaders more accurately, which suggests that the local structural property plays a more important role than the distance for identifying multiple influential spreaders.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
