1. A method for determining the network connectivity between a first node and a second node connected to the first node by at least one path, the method comprising: identifying paths to the second node from the first node within a network community; using processing circuitry to: determine a normalized path weight for each identified path; determine a user connectivity value for each identified path; for each identified path, sum the product of the user connectivity value and the normalized path weight to produce a network connectivity indication; and output the network connectivity indication.
