Patent number: 10783157Abstract: An online system provides a continuous feed of content items to a client device. The online system maintains an ordered set of ranked content items for sending to the client device. The online system receives requests from the client device for content items and selects a subset from an ordered set of ranked content items in response to each request. The number of content items in the subset may be based on factors such as the network connection strength of the client device. The client device re-ranks content items received from the online system based on information received during a given session. The session information may indicate the types of content items viewed during the given session, or the speed at which the user is viewing content items during the given session.Type: GrantFiled: June 15, 2018Date of Patent: September 22, 2020Assignee: Facebook, Inc.Inventors: Meihong Wang, Mahmud Sami Tas, Ansha Yu

Patent number: 10680992Abstract: Systems, methods, and non-transitory computer readable media are configured to subscribe a subscriber to a content item appearing at a first position in a news feed of content items based on selection of a setting to subscribe to the content item. A pop up window including a response associated with the content item on a user interface displayed by a computing device associated with the subscriber is presented to the subscriber based on posting of the response. Scrolling of the news feed in response to user inputs is concurrently presented on the user interface while the pop up window is presented. At least one selectable setting to dismiss the pop up window from view on the user interface is provided. In response to dismissal, the content item assumes the first position in the news feed or assumes a second position in the news feed based on a re-ranking.Type: GrantFiled: December 21, 2015Date of Patent: June 9, 2020Assignee: Facebook, Inc.Inventors: Meihong Wang, Ansha Yu, Yan Wu, Wenyuan Yu, Yisong Song

Patent number: 10419560Abstract: A social networking system presents content items to a user and determines if the user has less than at threshold level of interest in the presented content items based on one or more user interactions with the presented content items. For example, the social networking system determines the user has less than the threshold level of interest in the presented content items if at threshold number of requests for content are received within a time interval. If the user has less than the threshold level of interest in the presented content items, the social networking system identifies additional content items to present to the user, and may also identify content items previously presented to the user. Content is selected form the additional content items or from the previously presented content items and presented to the user.Type: GrantFiled: January 17, 2017Date of Patent: September 17, 2019Assignee: Facebook, Inc.Inventors: Yintao Yu, Meihong Wang

Patent number: 10345993Abstract: A social networking system selects and presents content items to a user via a feed. Additionally, the social networking system predicts heights associated with various content items, such as content items selected for presentation via the feed. Characteristics of a content item (e.g., a type of content included in the content item, a language of the content item, and a number of comments associated with the content item) as well as characteristics of a client device associated with the user are used to predict a height associated with the content item. When selecting content items for presentation to the user, the social networking system accounts for the predicted heights of various content items to increase the likelihood of the user interacting with content items presented via the feed.Type: GrantFiled: March 31, 2015Date of Patent: July 9, 2019Assignee: Facebook, Inc.Inventors: Yintao Yu, Meihong Wang, Di Liu, Wenjie Fu, Lars Seren Backstrom
