  • Publication number: 20230186071
    Abstract: The present disclosure relates to systems, methods, and non-transitory computer-readable media that utilize machine-learning models to classify content items and automatically organize the content items within a file structure according to their content item classifications. For instance, a content item classification system generates one or more content item classification models to determine classifications for content items and/or folders. In some instances, the classification system detects when new content items are added to a smart folder, determines destination folders to which the content items belong based on classifying the content items, and automatically moves the content items accordingly. In various instances, the classification system generates and utilizes a classification model to organize content items into dynamically-generated folders.

  • Publication number: 20230076870
    Abstract: Techniques are disclosed for protecting a user of a content management system from inadvertently or accidentally disclosing sensitive information contained in a content item hosted with the system. In response to receiving a request by the user to perform a sensitive information exposing action on the sensitive content item, the content management system performs a sensitive information protective action for the sensitive content item. By doing so, the techniques improve the operation of the content management system through increased information security.

  • Patent number: 11422721
    Abstract: Systems and methods for dynamic and automatic data storage scheme switching in a distributed data storage system. A machine learning-based policy for computing probable future content item access patterns based on historical content item access patterns is employed to dynamically and automatically switch the storage of content items (e.g., files, digital data, photos, text, audio, video, streaming content, cloud documents, etc.) between different data storage schemes. The different data storage schemes may have different data storage cost and different data access cost characteristics. For example, the different data storage schemes may encompass different types of data storage devices, different data compression schemes, and/or different data redundancy schemes.
