Re: [igraph] Reverse engineering affiliation networks

[Tamas Nepusz]

Hi,

This is not possible in general as it is easy to construct two networks which
result in the same affiliation network representation -- even if you use
weights to indicate the number of events attended jointly. For example, with
three people (A, B and C):

Case #1: A, B and C attended event E1.
Case #2: A and B attended event E1, A and C attended event E2, B and C attended
event E3.

In both cases, the affiliation network will be a triangle.
