Abstract: Disclosed are systems and methods for a materialized view matching framework that operates to improve the re-usability of materialized views within a database by, inter alia: i) enabling selection and aggregation of multiple materialized views; ii) generating and using validity filter predicates to exclude invalid data from materialized views; iii) generating and using change summaries to generate validity filter predicates; and iv) enabling on-demand transactional refresh operations. Such operations enable a more computational efficient and accurate usage of database data so as to provide more credible and desirable search results.

Abstract: Various embodiments disclose an in-message application facilitating the use of third-party application programming interfaces (APIs). In particular, these in-message applications (referred to as “cards”) may be designed by a developer to access third-party API functionality. A user may then create a message referencing, e.g., a web address associated with the developer's card. The system may receive the user's message and recognize the reference. The system may then distribute an instantiation of the card to various recipients, the instantiation including elements generated using, or providing the user access to, the third party functionality.

Abstract: A social networking system aggregates content related to the media events that have aired or are currently airing from a variety of sources, such as the entity broadcasting the media event and users that author content items referencing the media events. The social networking system generates multiple event interfaces that allow users of the social networking system to consume content, both user authored content and content curated from external sources, related to a media event. The interfaces include both content items that have a high correlation with the media events and visual representations of the user response to media event. Further, the interfaces include interface elements that allow users to easily navigate and interact with the information being presented as well as provide additional content related to the media events.

Abstract: A system can optionally include a social network database configured to store social network information records related to a user of the social network, wherein the social network database is configured to classify an individual information record according to the user of the social network and at least one of an application that generated the individual information record and an object of the individual information record. The system can further include a processor configured to identify ones of the information records as classified in the social network database based on at least one of the user and the at least one of the application and the object and transmit data indicative of a common characteristic of the ones of the information records to the social network.

Abstract: A system can optionally include a social network database configured to store social network information records, each information record including at least two of: an actor, a verb, an object, and an attributed entity. The system can further include a processor configured to generate a summary of one of the information records based the on at least two of the actor, the verb, the object, and the attributed entity of the information record, display on a developer user interface a rendering screen configured to format a display model based on a developer input, the display model including a summary field configured to display the summary, and transmit to a user device an interface screen based on the summary and the model.

Abstract: A facility for tracking the sharing of distinguished content is described. When a user seeks to access the distinguished content from a client computer system using a URL associated with the distinguished content, the facility determines whether a user identifier is represented in the URL. If a user identifier is represented in the URL that is different from a user identifier that is persistently stored by the client computer system, the facility determines that the distinguished content has been shared with a user identified by the user identifier that is persistently stored by the client computer system by a user identified by the identifier represented in the URL.

Abstract: Systems and methods are provided for instrumenting compiled software to include diagnostic information such that an origin of a call to one or more routines may be more easily identified. For example, a system is provided which unassembles or uncompiles software into a more readily identifiable instructional form, which is then searched to identify various calls to various routines of interest. Portions of the identified calls are then modified with diagnostic information that will identify the call. This diagnostic information and the call are then recorded so that the call may be subsequently traced back to its origin when, for example, an error occurs.

Abstract: Secure application programming interfaces are provided to enable communications between one or more services and one or more processes. The secure application programming interfaces expose services to the processes based on the trust level associated with the services and the trust level of the processes. The trust level of the processes are determined by performing a hash on the processes. The services exposed to the processes have a trust level less than or equal to the trust level of the processes. Accordingly, the secure application programming interfaces are generated on the fly based on the needs of the one or more processes.

Abstract: Ordered list management is described. An item's position within an ordered list is represented by a path value. A globally unique identifier (GUID) is appended to the path value to enable simultaneous or near-simultaneous modifications to the ordered list without conflict. Furthermore, an ordered list-specific seed value may be prepended to each item's path value to ensure clustering of ordered list items when two or more ordered lists are merged.
