Abstract: An online system provides video recommendations to a target user of the online system as a supplement to videos provided to the target user that were posted by the user's connections in the online system. The recommended videos are selected from publicly available video content and are likely to be of interest to the target user. The online system has video candidate generators that select video candidates based on a variety of selection criteria. The selected video candidates are filtered to identify inappropriate content or videos that the target user has already viewed for elimination from candidacy. The filtered video candidates are ranked based on weights of features of the video candidates. Based on the ranking, the online system selects videos above a threshold as recommendations to the target user.

Abstract: To allow a third party system to more particularly identify sets of users for distributing content, an online system receives data from a third party system identifying users of the online system who have authorized communication with the third party system and stores information authorizing communication between the third party system and the users in user profiles associated with the user. The online system receives a request from the third party system to transmit a notification to online system users satisfying criteria specified by the request. User profiles including information authorizing communication between the third party system and online system users are identified by the online system, which selects a set of the identified user profiles associated with information satisfying the criteria specified by the request.

Abstract: An online system regulates access to information about a user by associating an online system user identifier with a unique application-specific user identifier used by an application to identify the user. Each application communicating with the online system and installed by the user is associated with a unique application-specific user identifier that is associated with the user's online system user identifier. For example, information identifying an installed application and an application-specific user identifier are associated with the user's online system user identifier when the user installs the application. When communicating about a user with an installed application associated with the user, the online system identifies the user via the application-specific identifier associated with the installed application and may provide limited information associated with the online system user identifier associated with the application-specific identifier.
