Abstract: One or more processors analyze at least one first user input. One or more processors determine one or more interests of a first user based, at least in part, on the at least one first user input. One or more processors determine a proximity of the first user to one or more points of interest within a first threshold distance of the first user while the first user is mobile. One or more processors match at least one interest of the first user with one or more interests associated with a point of interest of the one or more points of interest. One or more processors provide a notification that the first user is within the first threshold distance of the point of interest.

Abstract: A social networking system maintains various groups that each include one or more users and maintains information describing interactions by users with the social networking system. The social networking system selects various content items provided to groups including the user based on amounts of interaction with content items provided to groups including the user by other social networking system users as well as amounts of time since the social networking system obtained various content items provided to the groups. Information describing the selected content items is presented to the user by the social networking system outside of pages of content maintained by the social networking system for groups to which the selected content items were provided.

Abstract: An online system predicts the user's activity on the online system during a future time interval (e.g., the next day). The system collects activity data, such as actions that the user has taken on the system. The system predicts whether the user is likely to be active during the future time interval based on features extracted from the activity data. This system determines selection of notifications and delivery of notifications based on the predicted time when the user is likely to be active on the online system. The system further records the user's past interactions with notifications, such as whether the user viewed the notification, whether the user interacted with a content item associated with the notification, and so on. If system determines a rate of delivery of notifications to the user based on the frequency of past user interactions with notifications.

Abstract: In one embodiment, a method includes receiving, from a client system of a first user of an online social network, an indication the first user is accessing a gaming platform; authenticating the first user to access to the gaming platform; receiving, from the gaming platform, a request to access social-networking information associated with the first user; providing, to the gaming platform, access to the social-networking information; receiving, from the gaming platform responsive to a call to a sharing-moments application programming interface (API), gaming-moment information that includes references to one or more in-game actions of the first user in a first game hosted on the gaming platform and metadata associated with each of the one or more in-game actions; and providing, to the client system of the first user, the gaming-moment information within one or more social contexts on the online social network.

Abstract: A first message may be displayed within a main chat room. The first message may be associated with a first topic. A second message may be displayed below the first message. The second message may be associated with a second topic. A third message may be received. The third message may be determined to be associated with the first topic. In response to the determining, the third message may be displayed by offsetting the third message below the first message, wherein the third message is displayed above the second message. The offsetting the third message below the first message may indicate a hierarchical relationship between the first message and the third message.

Abstract: Systems, methods, and non-transitory computer readable media configured to receive an initial targeting for an advertisement.

Abstract: The disclosed computer-implemented method may include measuring a user's activity for at least a current time period with respect to a social networking group of a social network. The method may include determining, based on at least the user's activity, whether the user will establish a meaningful connection with the social networking group for a next time period. The meaningful connection may indicate that the user satisfies a threshold amount of activity with the social networking group for a time period. The method may include selecting, based on the determination, content associated with the social networking group. The method may include providing the selected content for display to the user. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A first message may be displayed within a main chat room. The first message may be associated with a first topic. A second message may be displayed below the first message. The second message may be associated with a second topic. A third message may be received. The third message may be determined to be associated with the first topic. In response to the determining, the third message may be displayed by offsetting the third message below the first message, wherein the third message is displayed above the second message. The offsetting the third message below the first message may indicate a hierarchical relationship between the first message and the third message.

Abstract: A social networking system identifies a set of groups of which a user of the social networking system is not a member and selects a group for recommendation to the user based on a predicted affinity of the user for each identified group. The social networking system computes an affinity score of the user for each of one or more members of the selected group based at least in part on information describing a set of connections between the user and each member. Based on the scores, the social networking system selects a set of members of the group and generates a recommendation unit, wherein images associated with the selected members are arranged based on their scores and overlay at least a portion of an image associated with the group. The recommendation unit is communicated to the user to suggest that the user join the recommended group.

Abstract: A social networking system selects a set of groups for presentation to a user of the social networking system. To select groups, the social networking system determining scores for various groups representing a likelihood of the user interacting with the groups. When determining a score for a group, the social networking system accounts for a likelihood of the user providing content to the group as well as the user accessing or viewing content associated with the group. Based on the scores, one or more groups are selected and presented to the user. Additionally, the social networking system may apply one or more diversity rules so that the selected groups have a variety of characteristics.

Abstract: A social networking system allows users to create and join groups in the social networking system, in which each group is associated with one or more interests shared by members of the group. To select content for presentation to a viewing user of the social networking system who is a member of a group, the social networking system may determine one or more topics associated with the group based at least in part on a classification system and on information associated with objects maintained in the social networking system that are similar to the group. The topic(s) associated with the group also may be determined based on information associated with the group, with members of the group, and/or with objects associated with the group. The social networking system may then select one or more content items associated with the topic(s) for presentation to the viewing user via a group page.

Abstract: An online system provides group recommendations by applying a set of sourcing rules to identify a plurality of candidate groups and then generating scores for the candidate groups. The sourcing rules can be configured to identify a relatively small subset of the groups maintained by the online system. After the candidate groups are identified, the online system generates a score for each candidate group, ranks the candidate groups based on the scores, and sends high-ranking candidate groups to the target user to be displayed as recommended groups. As a result, the online system generates a smaller number of scores, which advantageously allows for the online system to provide group recommendations to users in a more computationally efficient manner.
