Network Scale(s)
• Scale-free networks?– Citation networks– The Web– Semantic networks– Depend on super nodes
• Semantic networks are ones where the nodes and relations are ‘named and typed’
‘Complex’ networks
• Based on information content– Node count and number of links– Spanning height– ‘Width’– Etc.
• Or complexity metrics, cf. McCabe – number of linearly independent paths through the network
• Open world networks, differing node relations… (or not)

Discussion
• We have the tools to explore these networks, collaboratively…
• Just beginning to look at a network rendering, i.e. initial queries
• Current limit is: base information models upon which to develop the initial knowledge base(s) (i.e. ontologies)
• Compute deductive closure, iterate… ?
• Thanks for listening. Questions?
