Abstract: Embodiments are provided for a dropsite. In some embodiments, information is received on a creation location and a date and time of creation of a content item, and a determination is made if (i) the date and time of creation is within a predefined span of time, and (ii) the creation location is within a predefined geographical area to permit association of the content item with a shared folder whose inclusion criteria match said date and time and geographic location.

Abstract: Methods, systems, and computer readable media for content item purging are provided. A contact item purger, such as may be incorporated within a local client application of a content management system running on a user device, may leverage knowledge as to which items have been uploaded to the content management system, and how long such content items have been stored on the user device, to propose items for deletion from the user device so as to reclaim storage space. A contact item purger may run on one or more user devices, and may activate upon various triggering events, based on various conditions and parameters, with or without user interaction, thus maintaining available memory capacity at all times.

Abstract: A content management system enriches contact records obtained from a client device using user records stored on the content management system. The content management system receives contact records from a client device authorized on a user account of the content management system. The content management system compares contact records with user profiles stored on the content management system. The content management system matches contact records with user profiles of user accounts with which at least one sharing event occurred between the user account and the user account on which the client device is authorized. The content management system identifies a matching user profile corresponding to the contact record. The content management system determines modification information for modifying the contact record based upon the matching user profile.

Abstract: Embodiments are disclosed for detecting duplicate and near duplicate images. An exemplary method includes receiving an original image, preparing the image for fingerprinting, and calculating an image fingerprint, the fingerprint expressed as a sequence of numbers. The method further includes comparing the image fingerprint thus obtained with a set of previously stored fingerprints obtained from a set of previously stored images, and determining if the original image is either a duplicate or a near duplicate of an image in the set if the dissimilarity between the two fingerprints is less than a defined threshold T. Once a duplicate or near duplicate is detected, various defined actions may be taken, including culling the less desirable image or referring the redundancy to a user.

Abstract: Embodiments are provided for organization and presentation of content. In some embodiments, a plurality of images and a plurality of similarity rules for image categorization are received. For each image in the plurality of images, that image and each remaining image from the plurality is compared by: applying each similarity rule to the image and a remaining image from the plurality to obtain a numeric result, and recording the numeric result for the pair of images in a numeric representation, the numeric representation embodying similarities. The numeric representation is used as a reference for clustering the plurality of images into clusters of similar images, and each image is stored with a marker denoting a cluster to which it has been assigned.

Abstract: Methods, systems, and computer readable media for content item purging functionality are provided. A contact item purger, such as may be incorporated within a local client application of a content management system, leverages its knowledge as to which items have been uploaded to the content management system, and how long content items have been stored on the user device, to propose items for local deletion and thus reclaiming storage on the user device. A contact item purger may run on one or more devices of a user associated with an account on a content management system upon various triggering events, and may run with or without user interaction, thus maintaining available user device memory capacity at all times.
