System and method for selecting content of a device based on probability of a device being linked

摘要

The present invention relates to associating computing devices with each other based on computer network activity for selecting content items as part of an online content item placement campaign. Wherein the first link factor is based on a connection between the first device and the computer network over a first IP address for a first time period and for the first time period between a second device via the first IP address and the computer network Lt; / RTI The number of devices connected to the computer network via the first IP address is determined. A positive match probability is generated. The second link factor and the third link factor are monitored. The negative match probability is determined based on the second link factor and the third link factor. The first device is coupled to the second device based on the positive match probability and the negative match probability.
