Background

The networks ND*.net are based on the files from Notre Dame Self-Organized Networks Database. To transform the data into Pajek format: vertex 0 was replaced by the vertex number equal to the number of vertices in a network; Pajek keywords were inserted; and the network was saved in the short (as lists of neighbors) format.

1. World-Wide-Web:: Each number represents webpage within nd.edu domain. Arcs: From page -> To page

2. Actor: Actor network data: (based on www.imdb.com) In the original ND network file: each line corresponds to one movie, each number represents actor: number_1 number_2 ... number_k (k actors who play in the same movie).

3. Protein Interaction Network for Yeast: Each number represents protein in protein interaction network of yeast. Edges: From protein -> To protein.
