Abstract
Link prediction and network alignment are two important problems in social network analysis and
other network related applications. Considerable
efforts have been devoted to these two problems
while often in an independent way to each other.
In this paper, we argue that these two tasks are relevant and present a joint link prediction and network
alignment framework, whereby a novel cross-graph
node embedding technique is devised to allow for
information propagation. Our approach can either
work with a few initial vertex correspondences as
seeds or from scratch. By extensive experiments
on public benchmarks, we show that link prediction and network alignment can benefit each other
especially for improving the recall for both tasks
