Patent number: 10521732Abstract: Systems, methods, and non-transitory computer-readable media can obtain a plurality of content items that are available to be presented in a content feed of a first user, wherein each content item has a corresponding lifespan that indicates when the content item expires and is no longer available for presentation. A content feed having at least a first content item from the plurality of content items can be provided to a computing device of the first user. A determination can be made that at least one second user has provided feedback for the first content item, the feedback indicating an up-vote or a down-vote of the first content item. The lifespan of the first content item can be adjusted based at least in part on the feedback.Type: GrantFiled: December 28, 2015Date of Patent: December 31, 2019Assignee: Facebook, Inc.Inventors: Adrien Thomas Friggeri, Brady John Brayley Voss, James Glessal Pearce, Spencer G.

Patent number: 9582587Abstract: Indexing and retrieving real time content in a social networking system is disclosed. A user-term index includes user-term partitions, each user-term partition comprising temporal databases. As a post is received from a user, a user identifier, a post identifier, and a post is extracted. An object store communicatively coupled to a temporal database for recently received content is queried to determine whether terms in the post has already been stored. A term identifier is stored in the user-term index with the user and post identifiers. A forward index stores the post by post identifier. Responsive to a search query, the user-term index is searched by the user's connections and the terms. A real time search engine compiles the results of the user-term index query and retrieves the stored posts from the forward index. The search results may then be ranked and cached before presentation to the searching user.Type: GrantFiled: September 6, 2016Date of Patent: February 28, 2017Assignee: Facebook, Inc.Inventors: Akhil Wable, Hong Yan, Spencer G.

Patent number: 8667064Abstract: A user device requests a web page from a web server of a third-party website, which is separate from a social networking system. The web server from the third-party website sends a markup language document for the requested web page to the user device which includes an instruction for a browser application running on the user device to incorporate information obtained from the social networking system within the web page. Based on the instruction in the received markup language document, the user device requests personalized content from the social networking system, which generates the requested personalized content based on social information about the user. The user device then renders the web page with the personalized content contained in a frame and displays the rendered web page and the frame to the user.Type: GrantFiled: July 15, 2012Date of Patent: March 4, 2014Assignee: Facebook, Inc.Inventors: Mark E.
