•Waarom was dat noodzakelijk?
•Drie belangrijkste dingen
•graph world: collab networks (bioi author collab; de moor?; Intl), www, citation nws, co-citatie/BC network (say:email comm)
•small worlds, scale-free, hub phenomena
•HITS
•Pagerank
•vector space model
•bibliometric retrieval, growth of bioi
•clustering, features:selection/construction; similarity; features based on text, based on citations, based on combination
