Networks from SNAP (Stanford Network Analysis Platform) Network Data Sets, Jure Leskovec http://snap.stanford.edu/data/index.html email jure at cs.stanford.edu Stanford web graph NOTE: see Kamvar/Stanford (matrix ID 979) in the UF Collection Dataset information Nodes represent pages from Stanford University (stanford.edu) and directed edges represent hyperlinks between them. The data was collected in 2002.

Files File Description web-Stanford.txt.gz Stanford web graph from 2002 NOTE: a similar version this problem already appears in the UF Collection: web-Stanford Kamvar/Stanford (same size and nnz) n: 281,903 nz: 2,312,497 The SNAP/web-Stanford graph and the Kamvar/Stanford graphs have the same number of nodes and edges. However, they differ in nonzero pattern.
