- QUOTE: ... Recent work shows that personalized PageRank (Jeh & Widom, 2003) can be used to directly incorporate multi-hop neighborhood information of a node without explicit message-passing [ 33 ]. Intuitively, propagation based on personalized PageRank corresponds to infinitely many neighborhood aggregation layers where the node influence decays exponentially with each layer. However, as proposed, Klicpera et al., 2019)’s approach does not easily scale to large graphs since it performs an expensive variant of power iteration during training.

- QUOTE: Personalized PageRank is a standard tool for finding vertices in a graph that are most relevant to a query or user. To personalize PageRank, one adjusts node weights or edge weights that determine teleport probabilities and transition probabilities in a random surfer model. There are many fast methods to approximate PageRank when the node weights are personalized; however, personalization based on edge weights has been an open problem since the dawn of personalized PageRank over a decade ago. In this paper, we describe the first fast algorithm for computing PageRank on general graphs when the edge weights are personalized.

In the PageRank model, a random walker moves through the nodes in a graph, at each step moving to a new node by transitioning along an edge (with probability $\alpha$) or by “teleporting” to a position independent of the previous location (with probability $\left(1 − \alpha\right)$).

- QUOTE: PPR is defined with respect to a “random surfer model” and needs to be computed iteratively. Informally speaking, PPR is the stationary distribution of random walks; at each step in a random walk, it randomly selects an outgoing edge from the current node, and, with a certain probability, it jumps to a node in accordance with a given preference distribution.

- QUOTE: In general, the appropriate notion of “proximity” may be task- or user-specific, and hence must be learned or engineered; however, there are also general-purpose graph proximity measures such as random walk with restart (RWR) (also called personalized PageRank) which are fairly successful for many types of tasks.

- QUOTE: Personalized PageRank expresses backlink-based page quality around user-selected pages in a similar way as PageRank expresses quality over the entire Web. Existing personalized PageRank algorithms can however serve on-line queries only for a restricted choice of page selection. In this paper we achieve full personalization by a novel algorithm that computes a compact database of simulated random walks; this database can serve arbitrary personal choices of small subsets of web pages.
