Dear all, I use UCINET 6 in order to study the formation, structure and topology of the collaborative R&D network in Greece. I have constructed three 2-mode networks (actors X projects), from which I constructed 3 affiliation datasets (actors X actors). My research question is whether there are any coincidences of lines among these 3 networks. Up to now, I have not been able to figure out how to do this. I would appreciate any suggestions.
