Abstract

In a “tipping” model, each node in a social network, representing an individual, adopts a property or behavior if a certain number of his incoming neighbors currently exhibit the same. In viral marketing, a key problem is to select an initial “seed” set from the network such that the entire network adopts any behavior given to the seed. Here we introduce a method for quickly finding seed sets that scales to very large networks. Our approach finds a set of nodes that guarantees spreading to the entire network under the tipping model. After experimentally evaluating 31 real-world networks, we found that our approach often finds seed sets that are several orders of magnitude smaller than the population size and outperform nodal centrality measures in most cases. In addition, our approach scales well—on a Friendster social network consisting of 5.6 million nodes and 28 million edges we found a seed set in under 3.6 h. Our experiments also indicate that our algorithm provides small seed sets even if high-degree nodes are removed. Last, we find that highly clustered local neighborhoods, together with dense network-wide community structures, suppress a trend’s ability to spread under the tipping model.
