Abstract: A social networking system provides a user with a feed of content items associated with other users connected to the user via the social networking system. Additionally, the social networking system identifies additional content items for presentation to the user and generates an additional feed including the additional content items. The additional content items may be determined by identifying content items having various characteristics and scoring the content items based on the characteristics. Content items having at least a threshold score are identified as additional content items. Examples of characteristics of content items include users providing content items to the social networking system, locations associated with social networking system users, and interaction with content items by social networking system users. In some embodiments, the additional feed modifies presentation of the additional content items based on their associated scores.

Abstract: 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.

Abstract: A client relationship management (CRM) application can generate a ranked list of client engagement tools by computing a rank score for available client engagement tools and determining an order among the available client engagement tools based on the rank scores. The CRM application can use one or more trained prediction models and business rules to compute a prediction for success for client engagement tools. For example, the CRM application can use three prediction models, one predicting user selection of a client engagement tool from a list of available client engagement tools; one predicting a user's adopting the recommendation in a client engagement tool; and one predicting a client approving a client engagement tool recommendation. The predictions for success can be combined with estimated benefit values for the client engagement tool to compute the client engagement tool rank score.

Abstract: Some embodiments include a method of detecting and analyzing virally propagating subject matter in a social networking system. The method includes processing user activities in the social networking system through a relevancy filter to identify a subset of user activities that are relevant to a viral propagation study. The social networking system can construct, in response to selecting a user activity as a graph exploration seed, a user activity cascade by exploring the social graph in the social networking system, starting from a social network node corresponding to the user activity. The user activity cascade can comprise social network nodes found during the graph exploration. The social networking system can determine that the user activity cascade is virally propagating based at least upon a total size of the user activity cascade.

Abstract: In one embodiment, a method includes accessing N electronic media-content items and a plurality of media-content templates, where each of the media-content templates includes a pre-determined number of surface areas for a pre-determined number of media-content items. The method includes scoring, based on one or more features, for each of one or more of the media-content templates, the placement of X of the electronic media-content items in the media-content template, where X equals the lesser of N and the pre-determined number of surface areas of the media-content template. The method includes selecting one of the media-content templates with a highest score and providing the X electronic media-content items in the selected media-content template for display to a user.

Abstract: A social networking system generates an augmented user profile for a user. The augmented user profile includes information from user profiles maintained by additional social networking systems that correspond to the user of the social networking system. For example, user profiles maintained by additional social networking systems having a threshold similarity to a user profile maintained by the social networking system are identified, and characteristics of the user in the identified user profiles are included in the augmented user profile along with characteristics from the user profile maintained by the social networking system. Characteristics of the user from the augmented user profile are used to identify content, such as advertisements, for presentation to the user.
