Abstract: Systems and methods for mapping identifiers are provided. Activity logs illustrate activities and/or events associated with a plurality of identifiers. The identifiers may be registered identifiers, unregistered identifiers, or a combination thereof. When at least two identifiers share a linking attribute, the at least two identifiers may be mapped to one another, along with information associated therewith (if any) such as a user profile. Each subsequent line of an activity line may also be mapped to the identifiers of the initial single line when a linking attribute or an overlapping identifier is present. A number of identifiers associated with each other may be increased by mapping identifiers and, thus, a targeted audience for a customized advertisement may, in turn, be increased.

Abstract: Large sets of unorganized data may provide little value in identifying useful observations from such data. For example, an online merchant may maintain a database of millions of user IDs (e.g., a cookie ID, a login ID, a device ID, a network ID, etc.) along with content viewed and/or actions taken with the user IDs, where minimal associations are known between user IDs. It may be advantageous to link together user IDs of respective users to capture a comprehensive view of respective users' activities. Accordingly, one or more systems and/or techniques for identifying a cluster of nodes based upon transforming a set of node pairings (e.g., pairings of related nodes) one or more times are disclosed herein. Iterative transformations may be performed until respective nodes are paired with merely their smallest neighboring node and are paired with no other node. In this way, node clusters may be identifiable.
