Network structure
All nodes the same sort of thing
Bipartite graph – two sorts of nodes
Can collapse a bipartite graph toget a new view over the data
Node and edges
Edges may be directed or undirected
Edges may be weighted
Categories become defined by relations between entities, rather
than the top down action of a cataloguer

Couple of network graphs to make the point…
