Pre-processing of social network structures for fast discovery of cohesive groups

摘要

Aspects and implementations of the present disclosure are directed to methods and systems of pre-processing a social network structure for fast discovery of cohesive groups. In general, in some implementations, a data processing system identifies a cohesive user group in a social network for delivery of a tailored content item. Generally, the data processing system identifies an affinity criteria; generates a set of user identifiers having characteristics that satisfy the affinity criteria; and generates graphs of users with at least one direct or indirect social network user connection with other user identifiers in the graph. The data processing system returns or stores the graph on computer readable media for later use. A graph may be generated with edges representing connections between user identifiers; edges may be weighted for the number and lengths of connection paths for indirect connections, and for similarities between users.
