    摘要: The World Wide Web (WWW) can be modelled as a labelled directed graph G(V,E,L), in which V is the set of nodes, E is the set of edges, and L is a label function that maps edges to labels. This model, when applied to the WWW, indicates that V is a set of hypertext documents or objects, E is a set of hyperlinks connecting the documents in V, and the edge-label function represents the anchor-text corresponding to the hyperlinks. One can find a probabilistic ranking of the nodes for any given label, a ranking of the labels for any given node, and rankings of labels and pages using flow based models. Further, the flows can be computing using sparse matrix operations.
