Abstract: A social networking system analyzes a user's interactions with objects linked to bookmarks associated with the user to generate a score for each bookmark. The score represents or is based on the probability that the user will access the bookmark or the linked object. For example, the score is a predicted click-through rate for the bookmark. Based on the scores, a subset of the bookmarks is selected for presentation to the user. Additionally, the scores may be used to order the selected subset of the bookmarks. Hence, the bookmarks that the user is most likely to access are presented while the bookmarks the user is less likely to access may be hidden.

Abstract: A method for filtering a notification being provided from an application to a user of a social networking system based on an action of the user is described. The method starts by receiving the notification from the application to the user. If the notification is a first notification sent from the application to the user, the notification is displayed to the user with (i) a prompting message that includes a selectable opt in image, and (ii) a selectable opt out image. The prompting message includes a request to opt in to receiving notifications from the application. If the notification is not the first notification sent from the application to the user, the method determines whether to display the notification to the user by determining whether the user previously opted in to notifications from the application and whether click-through rate (CTR) of notifications from the application is greater than CTR threshold.

Abstract: A social networking system displays stories describing actions to a user in a news ticker. The stories may be selected so that a variety of types of stories, stories associated with a variety of users, or stories associated with a variety of actions are presented via the news ticker. Additionally, stories having a common characteristic, such as being associated with a common user, may be aggregated and a description of the aggregated stories is presented in the news ticker. For example, stories aggregated based on acting user may identify the user common to the stories and a description of the aggregated stories may be displayed. Further, the value to the social networking system of displaying different types of content may be used to modify how different types of content are displayed in the news ticker.

Abstract: A social networking system determines the meaning of an anchor term used in a communication received from a communicating user. Candidate nodes are identified in the dictionary based on the anchor term, where each candidate node represents a possible meaning of the anchor term. The context of the anchor term is determined, and a score is determined for each candidate node based on the determined context. A candidate node is selected that most likely represents the meaning of the anchor term based on the determined candidate node scores. The context of the anchor term may be a social context derived from users connected to the communicating user that use the anchor term in communications. A communicating user may be prompted to identify the meaning of the anchor term explicitly based on the use of the term in communications from other users connected to the communicating user.

Abstract: A user saves a structured query defining connections between two or more objects maintained by a social networking system. The social networking system finds objects matching the structured query, either by periodically performing searches for new objects or by analyzing objects as they are added or modified. The user creating the saved query can subsequently view the matching objects.

Abstract: A notification system provides notifications to a user associated with multiple user devices. The notification system selects a user device to receive a notification based on user behavior, such as user interactions with the notification system via the user device or acknowledgments of notifications received from user devices. The notification is sent to the selected user device, and the notification system waits for an acknowledgment from the selected notification system for an acknowledgement delay period. If no acknowledgment is received within the acknowledgment delay period, an additional user device is selected and the notification is sent to the additional user device.
