Abstract: A signature matrix is used to test each online event for inclusion of a user in a pre-generated lookalike audience. Locality Sensitive Hashing is used to compile the signature matrix to dramatically reduce memory storage requirements and processing time for each received online event. A technique of producing incremental signature matrices between generation of the full signature matrix helps to enable near-real time performance in processing each received event to see if a user associated with that event should be added to one of the lookalike audiences pre-generated by advertiser.

Abstract: Techniques are provided for server-to-server interaction for content item selection. A system receives a request for one or more content items from a client device. In response to receiving the request, the system generates multiple content requests. Each content request is sent to a different content provider of multiple content providers. At least one of the content requests is transmitted over a network to a content provider that is remote relative to the system. The system receives multiple responses, each of which is from a different content provider of the multiple content providers. Each response identifies a different content item. The system makes a determination that at least one content item is associated with a particular web domain. The system selects, based on the determination, a particular content item of the plurality of content items and causes the particular content item to be transmitted to the client device.
