The rise and fall of network stars: Analyzing 2.5 million graphs to reveal how high-degree vertices emerge over time

作者:

Highlights:

• We constructed the largest publicly available network evolution dataset to date, which contains 38,000 real-world networks and 2.5 million graphs.

• Links are most prevalent among vertices that join a network at a similar time.

• The rate that new vertices join a network is a central factor in molding a network’s topology.

• The emergence of network stars (high-degree vertices) is correlated with fast-growing networks.

• A novel flexible network-generation model based on large-scale real-world data is presented.
