Abstract: Systems, methods, and devices identify devices and assign keywords to such devices. Methods include retrieving data from at least one data source, the data comprising a plurality of data events associated with a plurality of devices, and generating a plurality of probability metrics for each of the plurality of devices based on device information and data event parameters included in the retrieved data. Methods also include generating an activity estimation parameter for each of the plurality of devices based on the plurality of probability metrics, the activity estimation parameter comprising an estimated probability of a subsequent data event being taken by a device.
