Publication number: 20240126821Abstract: Techniques for providing suggested content is described. For example, a social networking system may receive, from an account of a social networking system, an indication of a selection of a first content item. The social networking system may determine that the first content item is associated with a first topic and may receive a request from the account to access a second content item associated with the first topic. The social networking system may then cause presentation of the second content item and may determine that the request meets or exceeds a threshold number of requests for content items associated with the first topic. Based on determining that the request meets or exceeds the threshold, the social networking system may cause presentation of a suggested content item associated with a second topic.Type: ApplicationFiled: October 17, 2022Publication date: April 18, 2024Inventors: Han Ren, Shruti Bhutada, Jus-Tin Cheng, Ellen Yutong Lu, Rehman Khan, Jonathan Eusung Kim, Shilpa Mody, Woo Jung Oh, Kyle Yank Zhu, Gargi Apte, Moira Kathleen Ballantyne Burke

Publication number: 20040236752Abstract: Separate file servers are located in different geographic areas to serve users in each area. A centralized system manager with communication links to the file servers and users controls documents stored in the file servers. The system manager must approve each request by a user to download a document from a local file server. If the requested document is not stored at the local file server, the system manager will cause the requested document to be transferred from another file server to the local file server for access by the user. Documents being accessed by users are locked thereby denying access to other users until the current access by another user of the sought document is terminated.Type: ApplicationFiled: May 19, 2003Publication date: November 25, 2004Inventors: Keli Han, Ren Lu, ZhongJin Yang, Jie Yao, Joe Ping Zhou
