  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.
