Methods, apparatuses, and computer program products are herein provided for providing a REVV system that is configured to provide an MVS that is operable on a mobile terminal. One example method may include causing a plurality of vector word residuals to be aggregated for at least one visual word using local feature descriptors extracted from an image. The method may further include causing the dimensionality of the aggregated at least one vector word residual for each visual word to be reduced by using a classification aware linear discriminant analysis. The method may further include computing, using a processor, a weighted correlation for at least one compact image signature that is binarized from the aggregated at least one vector word residual when compared to a list of candidates. The method may further include determining a ranked list of candidates based on the computed weighted correlation.

Techniques to increase engagement with a social networking system. In one embodiment, activities are prioritized based on relatedness to a user. References associated with at least a portion of the prioritized activities are created. The references are categorized into a plurality of types. The reference types may include notifications, friend identifications, and top stories. The references are embedded in digest communications for the user. Descriptive information about the activities are omitted from the digest communications. Digest communications for the user are provided during a time period when the user is not engaged with the social networking system. Notifications for a user are ceased when a level of engagement of the user with the social networking system is less than a threshold value.

Techniques to optimize messages sent to a user of a social networking system. In one embodiment, information about the user may be collected by the social networking system. The information may be applied to train a model for determining likelihood of a desired action by the user in response to candidate messages that may be provided for the user. The social networking system may provide to the user a message from the candidate messages with a selected likelihood of causing the desired action.

A method of tracking an inventory of objects via a mobile communications device includes acquiring an image of one or more of the objects via the mobile communications device, which also collects a location of the mobile communications device while acquiring the image of the one or more of the objects. The location and image are transferred from the mobile communications device to a remote server via a wireless network, such that the one or more of the objects are identified at the server based on the image, and the location and identity of the one or more objects are stored on a database associated with the server.

Techniques to increase engagement with a social networking system. In one embodiment, an engagement level of a user with a social networking system is monitored. A low engagement user type associated with the user is identified from a plurality of low engagement user types. It is determined whether the engagement level of the user is less than a threshold. If so, a communication is provided for the user based on the low engagement user type associated with the user. The communication may be a notification or a digest communication.
