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

Follower Communities

Couple of network graphs to make the point…

Commonalities and differences

Aquote from this month's Racecar Engineering,in a comment piece by Paul Weighell:

“Whitworth's core concept was accuracy in

measurement, which is what we would term today ‘enabling’technology. ... It is, I believe, still a general rule that technology advances by first improving standards of measurement and accuracy.”

Static and dynamic analysis of networks

Structural vs traffic analyses
