Social graph: create the links

You are given a snapshot of the social graph G = (N, E, t) at time t. Each node has a set of attributes (a1, a2, ... an). Three problems:

1. Create an edge if two nodes have exactly the same set of attributes
2. Create an edge if two nodes have similar attributes
3. What if a set of weights it's known a-priori for the attributes?
