Abstract
Estimating similarity between vertices is a fundamental issue in network
analysis across various domains, such as social networks and biological
networks. Methods based on common neighbors and structural contexts have
received much attention. However, both categories of methods are difficult to
scale up to handle large networks (with billions of nodes). In t
