- QUOTE: Through these edge and node weights, PageRank can be personalized to particular users or queries. Concretely, in node-weighted personalized PageRank, we solve $Mx(w)=(1-\alpha)v(w),\quad w\in \R^d$
where $w$ is a vector of personalization parameters. In edge-weighted personalized PageRank, we solve
$M(w)x(w)=(1-\alpha)v,\quad w\in \R^d$For example, the personalization vector can specify the topic preference for the query, so the random walker will teleport to nodes associated with preferred topics (node-weighted personalized PageRank) or move through edges associated with preferred topics more frequently (edge-weighted personalized PageRank).
