Bipartite projection with Graphx
Hi,
Is possible Bipartite projection with Graphx
Rdd1
#id name
1 x1
2 x2
3 x3
4 x4
5 x5
6 x6
7 x7
8 x8
Rdd2
#id name
10001 y1
10002 y2
10003 y3
10004 y4
10005 y5
10006 y6
EdgeList
#src id Dest id
1 10001
1 10002
2 10001
2 10002
2 10004
3 10003
3 10005
4 10001
4 10004
5 10003
5 10005
6 10003
6 10006
7 10005
7 10006
8 10005
val nodes = Rdd1++ Rdd2
val Network = Graph(nodes, links)
with above network need to create projection graphs like x1-x2 weight (see
the image in below wiki link)
example:
