Motivated by numerous models of representing trust and distrust within a graph ranking system, we examine a quantitative vertex ranking with consideration of the influence of a subset of nodes. An efficient algorithm is given for computing Dirichlet PageRank vectors subject to Dirichlet boundary conditions on a subset of nodes. We then give several algorithms for various trust-based ranking problems using Dirichlet PageRank with boundary conditions, showing several applications of our algorithms.
