Methods for detecting a common user of a plurality of user devices in a network and for detecting a common cohort for a plurality of users are disclosed. The methods comprise receiving a plurality of event records. Each of the event records corresponds to an event in a network and comprises a device identifier and event information. A correlation is then calculated between a first subset of the event records having a first device identifier and a second subset of the event records having a second device identifier. Based on the correlation, it is then calculated whether the first and second device identifiers relate to user devices associated with the same user, and whether the first and second device identifiers relate to user devices associated with users belonging to a common cohort. |
