  • Patent number: 9996535
    Abstract: Systems and methods are provided for generating organization data for an efficient presentation and/or organization of a collection of items. In some embodiments, the organization data may be based on metadata associated with items, such as keywords. The metadata may be generated from natural language processing of the items. Organization data and/or a hierarchical data organization may be a tree data structure that can be efficiently navigated to reach and/or locate an item. In some embodiments, organization data may be automatically updated in response to a document removal, addition, and/or a user selection. For example, as items are removed and/or added to the collection, keywords, counts, directories, nodes, and/or levels of the organization data may update and/or change to reflect the updated collection of items.
