Second-pass ranker for push notifications in a social network

Abstract

Systems and methods for providing push notifications of social network content items include determining first and second engagement values for first and second content items, respectively, provided by first and second content item sources, respectively, based on previous interactions with content items. First and second utility values are determined for the first and second content items, respectively, based on a mathematical operation applied to the first and second engagement values, respectively, the first and second selection metrics, respectively, and, for the first utility value, the value metric. One of the first and second content items are determined as a push content item based on a difference between the first and second utility values and displayed on a user device.

What is claimed is: 
     
         1 . A method, comprising:
 determining, with a processor, first and second engagement values for first and second content items, respectively, provided by first and second content item sources, respectively, based on previous interactions with content items from the first and second content item sources as stored as activity data of member information, associated with a member of an online social network system and activity data by the member on the online social networking system, as stored in an electronic data storage;
 the first content item provided based on a first selection metric in relation to the member information and a value metric, the member information accessed from an electronic data storage configured to store member information associated with a member of an online social network system; 
 the second content item being different than the first content item and provided based on a second selection metric in relation to the member information; 
   generating, with the processor, first and second utility values for the first and second content items, respectively, based on a mathematical operation applied to the first and second engagement values, respectively, the first and second selection metrics, respectively, and, for the first utility value, the value metric;   determining, with the processor, one of the first and second content items as a push content item based on a difference between the first and second utility values; and   causing, with the processor, via a network interface, a user device associated with the member to display the push content item as a push notification.
