21. Core-periphery
Summary Results
Hubs attract much more weight.
Most of the weight between hubs.
Low degree node connect to hubs.
Low degree nodes cluster locally.
Consistent with core-periphery structure. But, seems also present
in bipartite randomisation. Largest deviations, empirically:
Degree is lower, average weight is higher.
Weighted neighbour degree increases.
22. Model
Simple model to overcome deviations:
1 Create empty sentence
2 Add certain number of nodes
1 Either random node (with PA)
2 Or random neighbour (with PA)
Probability (ki + 1)

27. Conclusions
Results:
Network looks like core-periphery.
Probably due to bipartite structure.
But also to repetitive interaction.
Further research:
Basis for comparing elite networks.
Compare networks across time and space.
Dynamical, temporal aspects.
