I'm currently working on dynamic graphs with Gephi (that's quite a surprise, isn't it ?) and I'm facing a very common (I guess) issue, but I wasn't able to find a solution, neither on this forum nor on the Internet.
The data I use to build my graph is composed by :
A list of nodes (id, label, etc., date of birth). I use DoB to build a time interval column (one-bound).
A list of edges (source, target, etc., date/time). I use date to build a time interval column (two-bounds).
The semantic of my edge list can be seen like a phone call between two nodes. Therefore, there can be multiple occurrences of one edge, but at different times.
Example :
Code: Select all
Src Trgt Time
1 2 42
1 3 44
1 3 73
1 4 37
2 1 13
For the previous example data it would give me :
Code: Select all
Src Trgt Time Weight
1 2 42 1
1 3 44 2
1 4 37 1
2 1 13 1
My question is : how can I import my data so that I don't loose information ?
