In any case, this gives you a 2-mode network. Transform it to a 1-mode (easy in any tool) and you’ll get your Group-Group network. There are different approaches how to “count” co-occurrence of Individuals. You can sum them. Or you can weigh them, e.g. if I1 and I2 are just in G1 this might bring more “points” for G1 than I1 and I2 being everywhere. But this part should be derived from your questions. What do you want to analyze with this co-occurrence?

Betreff: [SOCNET] Question About Data Entry Format
***** To join INSNA, visit http://www.insna.org *****Hello Everyone,
This may be too simple and I may be overthinking it but I was hoping to get some feedback on the best way to manage some data. I have individual records where everyone is a member of two to three groups. There is a total of about 30 groups people can be a member of, but each is a member of at least two.
Now, we are not necessarily concerned about the individuals, but we need them to show the connection between the groups. We are really interested in the number of connections between the 30 groups and identifying areas of overlap and possible intervention to encourage collaboration among the silos.
Currently, the data looks a little something like this:(Example 1)
Group A Group B Group C Group D (…etc) Individual 1 0 1 0 1 Individual 2 1 1 0 1 Individual 3 0 0 1 0
One idea someone suggested was to alter the data as (example 2)
Group A Group B Group C Group D (…etc) Group A 1 1 1 1 Group B 1 0 0 1 Group C 1 1 1 1
The challenge with this is that Group A could have 100-200 individuals who are a member of group A and group B.
Is the data in example 1 the best way to handle it? Or is there an obvious solution I am blanking on right now?
Thanks for any help-
