A contact identification system provides a network of members with each member of a network having a relationship with one or more other members of the network. The contact identification system identifies relationship paths between a first member of a first network and a second member of a second network by traversing relationships to identify relationship paths that include a common member that is common to both the first network and the second network. The contact identification system generates an intermediary score for each identified relationship path to indicate whether the identified relationship path includes an intermediary who can effect a successful introduction between the first member and the second member. The contact identification system then identifies as potential intermediaries the common members based on generated intermediary scores.
