Abstract: The present disclosure relates to methods and systems for recommending a context to a user of a social network service, based on detecting an interaction with some item of web content. With some embodiments, after detecting an interaction with a web document, a topic to which the web document is related is determined. A context, such as an online or offline forum, known to be associated with the topic is then identified. Finally, the identified context is presented to the user as a recommendation for a content source that is likely to be of interest to the user.

Abstract: A fact checking system verifies the correctness of information and/or characterizes the information by comparing the information with one or more sources. The fact checking system automatically monitors, processes, fact checks information and indicates a status of the information.

Abstract: A method for a computer system includes receiving a first user communication, determining a first group of users, determining a target number of users, determining whether the first group of users includes the target number of users, and if not, providing the communication to the first group of users, determining a hierarchal mapping of groups of users in response to user memberships, determining a second group of users from the hierarchal mapping, determining a plurality of social network relationship factors for the second group of users with respect to the first user, and providing the communication to at least a subset of users in the second group of users in response to the first plurality of social network relationship factors.

Abstract: Example systems and methods of content sharing via social networking are presented. In one example, availability of a first user device to provide media content over a communication network is detected. A second user device is identified via an association of the first user device with the second user device that is specified in a social network. An acceptance by the second user device to receive the media content from the first user device is determined. In response to the acceptance, transmission of the media content provided by the first user device over the communication network to the second user device is initiated.

Abstract: A system, method, and apparatus are provided for distributing a content item toward target recipients solely via first degree connections (e.g., in a professional network, in a social network). For a selected content item and identified target recipients of the item, when a user initiates a message to forward or otherwise convey the content item, one or more schemes are applied to select and automatically populate the message with suitable addressees. In one scheme, values are computed for each neighbor of the sender, to indicate the value of delivering the item to that neighbor; the message is automatically addressed to the highest-value neighbors. In another scheme, user communities that encompass the target recipients are identified and the message is automatically addressed to neighbors that are best able to disseminate the item throughout a community. In another scheme a minimal set of neighbors having connections to all target recipients is identified.

Abstract: A method and system to determine member profiles for off-line targeting is described. An example system comprises an access module to access a member profile in the on-line social network system, a category score module, a member segmentation module, and a communications module. The category score module may be configured to generate a definition score for the member profile based on phrases that are present in the member profile, generate a propensity score for the member profile based on behavior data of a member represented by the member profile, and combine the definition score and the propensity score to generate a subscriber score for the member profile. The member segmentation module may be configured to compare the subscriber score of the member profile to a threshold value. The communications module may be configured to selectively send a communication to the member based on a result of the comparing.

Abstract: The disclosed embodiments provide a reputation system. The reputation system includes a ranking apparatus that obtains a set of reputation scores for one or more dimensions of a set of items in the reputation system and generates a ranking of the items based on the reputation scores and the one or more quantiles. The reputation system also includes a query-processing apparatus that obtains a query comprising the one or more dimensions and one or more quantiles associated with the one or more dimensions and provides the ranking in a response to the query.

Abstract: The disclosed embodiments provide a reputation system. The reputation system includes a statistical model associated with a set of items and a set of dimensions of the items in the reputation system, wherein the statistical model is trained using a positive class and a negative class. The reputation system also includes a scoring apparatus that applies the statistical model to a set of features for each of the items to estimate a set of reputation scores for the items. Finally, the reputation system includes a ranking apparatus that enables use of the set of reputation scores in the reputation system.

Abstract: Disclosed in some examples are methods, systems, and machine-readable mediums which provide a relevance engine for determining a relevance of an individual (either a non-member or another member) to another individual (either a non-member or another member). This relevance engine may use signals in the form of data that the social networking service may learn about the individuals to determine how relevant the individuals are to each other. Example applications may include ordering of connection invitations in a social networking service.

Abstract: The disclosed embodiments provide a method, system, and apparatus for facilitating use of a software library project. During operation, the system obtains a set of data associated with use of the software library project, wherein the data comprises a set of dependencies of calls and objects associated with the software library project. Next, the system applies a set of business rules to the data to assess one or more characteristics associated with the software library project. The system then enables use of the data and the one or more characteristics in assessing a health of the software library project.

Abstract: The disclosed embodiments provide a system that facilitates access to content associated with a group.

Abstract: A multi-tenancy storage node is provided. The storage node hosts partitions of multiple databases accessed by multiple applications. Each database is governed by a corresponding service-level agreement (SLA) or policy that specifies a maximum load or level of operation of the database in terms of one or more metrics (e.g., number or frequency of reads/writes, maximum size of reads/writes). To determine whether another database can be hosted by the node, a snapshot of the node's database operations is replayed on a test node, along with operations that exercise the other database. If maximum thresholds of the node for the metrics are not exceeded, the other database can be added to the storage node. An SLA is generated for it automatically, based on the metrics it exhibited during the operations on the test node. The storage node may enforce the SLA by rate-limiting activity of one or more applications.
