TITLE: The Link Prediction Problem for Social Networks | |
Abstract—
Given a snapshot of a social network, can we infer which new interactions among its members
are likely to occur in the near future? We formalize this question as the link prediction problem,
and develop approaches to link prediction based on measures for analyzing the "proximity" of
nodes in a network. Experiments on large co-authorship networks suggest that information
about future interactions can be extracted from network topology alone, and that fairly subtle
measures for detecting node proximity can outperform more direct measures.
