Abstract:Personalized PageRank (PPR) is a popular node proximity metric in graph mining and network research. Given a graph πΊ = (π , πΈ) and a source node π β π , a single-source PPR (SSPPR) query asks for the PPR value π (π’) with respect to π , which represents the relative importance of node π’ in the context of the source node π . SSPPR queries are widely used in recommendation, web mining, and graph representation learning, and their efficient processing has been intensively investigated over the last several… Show more
