Content recommendations
Users consume a wide variety of content from various sources, such as videos accessible through websites. As provided herein, content recommendations that are contextually and/or semantically relevant to current content consumed by a user may be identified and provided to the user. For example, metadata for a video being watched by the user may be identified (e.g., terms extracted from a description, user reviews, a category, and/or other information). The metadata may be used to identify content recommendations based upon the metadata corresponding to terms grouped into a set of refined topic groupings of a graph comprising terms and relationships between terms extracted from a content corpus. The metadata may be matched to relevant terms within the set of refined topic groupings, and content recommendations comprising content corresponding to the relevant terms may be suggested to the user. |

System, method, and computer-readable medium for managing image
A system for managing images obtains an image that is captured by an image capture device at an image capture position and an image capture time; and stores the image, the image capture position, and the image capture time. The system further determines a position of a subject included in the image based on the image capture position. The system further stores index information comprising a target identifier of the subject, the position of the subject, and the image capture time in association with the stored image. The system further determines index information corresponding to the search instruction when obtaining a search instruction of the image; and extracts the image corresponding to the determined index information. |

Content-aware filter options for media object collections
A method and apparatus are provided for navigating through a media object collection using a mobile device. Users navigate to the target media objects by repeatedly specifying filters. After a user specifies a filter, the filter is applied in combination with all previously specified filters to produce a filtered set of media objects. After a filter is applied, a display level is selected for each hierarchical dimension for which the media objects have metadata. The selection of the display level may be based on the number of distinct values that the media objects in the filtered set have for each level of the hierarchical dimension. Single-action controls are then displayed for each of the values that the media objects in the filtered set have for the selected display level. |

System and method for classification of low relevance records in a database using instance-based classifiers and machine learning
Devices and methods for classification of low relevance records in a database are disclosed. A method includes: in response to a request to delete a selected database record, generating a vector representation of the selected record, deleting the selected record in the database, and storing the vector representation of the deleted selected record; in response to the storing the vector representation of the deleted selected record, determining a cluster from which the vector representation has a shortest determined distance, among a plurality of clusters into which a plurality of vector representations of deleted records is partitioned; determining a distance between a record in the database and a nearest cluster among the plurality of clusters into which the plurality of vector representations of deleted records is partitioned; and in response to the record being within a predetermined distance of the nearest cluster, determining that the record is a deletion candidate record. |

Generating event suggestions for users from social information
A social networking system suggests events for a target user based on stored data in the social networking system related to the target user and to events. The social networking system may suggest events based on the target user's affinity for, connections with, or interactions with objects in the social networking system connected to or otherwise associated with the events. For example, an event is suggested to a target user if users connected to the target user already accepted an invitation to the event. As another example, an event organized by a particular entity is suggested to the target user because of interactions between the target user and other content provided by the entity. Invitations to suggested events may be presented to the target user via a client device, allowing the target user to easily join a suggested event. |

Sub-scope synchronization
Systems and methods for synchronizing data between an online data source and a client application. The method includes, in response to a change in a permission associated with a user to a protected data set included in a shared data space of the online data source, receiving, with the client application associated with the user, a protected data synchronization token issued by the online data source associated with the protected data set and downloading, with the client application, the protected data set included in the shared data space from the online data source to the client application using the protected data synchronization token without re-downloading a public data set included in the shared data space. After downloading the protected data set, the method includes synchronizing the shared data space, including the protected data set and the public data set, using a stored data space synchronization token. |

Replicating containers in object storage using intents
Systems and methods for replicating containers in object storage using intents are disclosed. A DS processing unit, upon reception of a write request may determine the location of replicated instances for the container. DS processing unit can then generate an intent for each fork, to indicate a specific write request received. The DS processing unit may save or persist intent objects within one of the containers, or in a dispersed data structure. A DS unit or DS processing unit may then check for intents whose operation has not been completed, and when resources to perform the operation are available, perform the operation specified in the intent. DS processing unit can remove a pending intent once the job or operation is complete. A clean-up agent could run periodically to complete unfinished jobs that are pending within DS processing unit or DS unit due to containers not being available for whatever reason. |

Data system with asynchronous batch processing
A data processing manager receives a batch of data for real-time data processing. The batch of data is associated with a correlation identifier and includes a set of data objects. The data processing manager assigns, to each data object, a unique resource identifier. The data processing manager transmits a data processing request to a target data system, and the data processing request includes a set of callback functions corresponding to the set of data objects. The callback functions identify the unique resource identifier. As the target data system processes the data objects, the target data system executes the callback functions, which operate as dynamic return endpoints for the data processing results. |
