Two-mode networks

1. Definition of two-mode networks
2. Transforming two-mode networks to ordinary valued networks
3. Normalisations of obtained valued networks
4. Line islands
5. Blockmodeling
6. Examples:
   • people and events - Davis Southern Club Women:
     • matrix,
     • two-mode network - figure,
     • valued network - women,
     • valued network - events.
   • Slovenian Journals and Magazines:
     • Geo normalisation: figure 1, figure 2,
     • MinDir normalisation: figure 1, figure 2.
7. Two-mode networks in Pajek

1. Analyse and draw given-two mode networks.

1. Analysis of given two-mode network:
   • visualization of two mode network using matrix and graph
   • blockmodeling of 2-mode network: image matrix, block error matrix, reordered matrix according to clusters obtained
   • transformation of two mode network to both ordinary valued networks
   • visualization of both obtained valued networks using matrix and graph
   • analysis of both obtained valued networks (select two out of three options below):
     • islands
     • community detection methods
     • normalizations (Geo, MinDir)
2. Interpretation of results.
