A method for identifying influence paths in a communication network comprising a plurality of users is disclosed. The method comprises identifying network parameters indicative of a strength of connection between users of the network, combining the identified parameters to calculate a connection strength between users of the network, storing the calculated connection strengths as edge weights between the users of the network, identifying a source user and a target user for a path, and calculating a path between the source user and the target user according to the stored edge weights. Also disclosed is a method for compression of a network and a network element and computer readable medium.
