Abstract: A collaborative content management system (CMS) is disclosed herein for generating templates for received documents. The disclosed CMS recognizes that a document selected by a user for processing was previously processed by the CMS and that a user has previously added particular overlaid fillable fields to the document. When the determination is made, the system generates a recommendation to create a template of the document with the previously added overlaid fillable fields. In some embodiments, the CMS makes the recommendation to generate a template when the user creates, in a received document, identical overlaid fillable fields or field types to those created in the previously processed document.

Abstract: Computer-implemented techniques encompass using distinct machine learning sub-models to score respective types of candidate content for the purpose of providing personalized content suggestions to end-users of a content management system. The relevancy scores generated by the distinct sub-models are mapped to expected end-user interaction scores of the candidate content scored. Content suggestions are provided at end-users' computing devices where the suggested content is selected from the candidate content based on the expected end-user interaction scores of the candidate content. For each distinct sub-model, a normalizing mapping function is solved using an optimizer that maps the relevancy scores generated by the sub-model for the candidate content to expected end-user interaction scores for the candidate content. The expected end-user interaction scores are comparable across the distinct sub-models and can be used to rank content suggestions across the distinct sub-models.

Abstract: A content management system generates a personalized vocabulary for a user by analyzing content items associated with a namespace of the user. The content management system receives a query. The content management system determines that the at least one search term does not occur at least a threshold number of times in the personalized vocabulary. The content management system identifies a prefix of the at least one search term. The content management system parses the personalized vocabulary based on the prefix to identify a set of search term options. The content management system generates a personalized ranking of the search term options based on (a) an edit distance; (b) a frequency of each search term option's occurrence in the personalized vocabulary; or (c) a combination of (a) and (b). The content management system presents at least a top ranked search term option to the user.

Abstract: In some embodiments, upon detecting malicious activity associated with a user account, a content management system can identify other user accounts related to the malicious user account. The content management system can identify related user accounts by comparing authentication information collected for the malicious user account with authentication information collected for other user accounts. Authentication information can include IP address information, geographic information, device type, browser type, email addresses, and/or referral information, for example. The content management system can compare the content items associated with the malicious user account to content items associated with other user accounts to determine relatedness or maliciousness. After identifying related malicious user accounts, the content management system can block all related malicious user accounts.

Abstract: The disclosed technology relates to a system configured to detect a delete event for a content item at a first location on a local file system of a client device, wherein the first location on the file system is managed by a content management service. The system determines a second location for the content item and whether the delete event is associated with an add event for the content item based on the second location of the content item. If the delete event is associated with the add event, the system processes the delete event with the add event in a unitary update to a local tree, wherein the local tree represents a file system state.

Abstract: Systems or methods for generating a plurality of different custom links that have different viewing options for viewing the same shared content item in customized content item players and displaying engagement analytics for how viewers are viewing shared content items, such as videos, are disclosed. A custom link to view the shared content item is generated in association with settings that are customized by an administrator. Once the custom link is accessed, a customized content item player is generated based on the settings. Once the content item is being played in a customized content item player, the engagement analytics are populated in real-time in a graphical display. The different engagement levels and graphical representations of segments of viewing are distinguished based on the engagement levels.

Abstract: The present disclosure relates to systems, non-transitory computer-readable media, and methods for generating a content stack utilizing one or more machine-learning models. In some implementations, the disclosed systems generate and provide, to a user account, a content stack that includes content items corresponding to a topic prompt for the user account. For instance, in some implementations, the disclosed systems utilize content-based signals and account-based signals to generate an account-specific stack formulation graph that represents a plurality of content items and relationships of the content items with each other and with the user account. Additionally, in some implementations, the disclosed systems analyze the account-specific stack formulation graph to generate a content stack from the plurality of content items, the content stack comprising a set of content items corresponding to the topic prompt.

Abstract: A system can selectively synchronize content based on synchronization settings. In some examples, a client stores a local tree representing a local set of content items associated with an account on a content management system, the local tree including respective local nodes corresponding to the local set of content items. The client stores a remote tree representing a remote set of content items associated with the account, the remote set being stored at the content management system and including respective remote nodes corresponding to the remote set of content items. The client receives a synchronization setting disabling local storage of the content item. In response, the client deletes a local copy of the content item, removes a corresponding local node from the local tree, and adds, to a remote node on the remote tree, an attribute indicating that local storage of the content item has been disabled.

Abstract: A system and method for displaying pinned content in a user interface is described herein. A collaborative content management system displays pins in an order personalized to a user. The collaborative content management system receives a command to output a user interface with a set of pins corresponding to a collaborative content item. For each pin, the collaborative content management system inputs data corresponding to the pin into a machine learning model and receives from the model the probability that the user is interested in the pin. The collaborative content management system ranks the set of pins based on the computed probability and outputs the user interface with at least one pin based on the ranking of the set of pins.

Abstract: One or more embodiments allow a user to search a gallery of digital content. In particular, a user can interact with a digital content system to search for, and identify, one or more digital content items (e.g., photos, videos, audio) within a collection of digital content. For instance, the digital content system can maintain tokens with respect to a collection of digital content and associate the tokens with digital content items within the collection of digital content. The digital content system can also provide a gallery of digital content items within a view area of a graphical user interface. Upon receiving a search query, the digital content system can identify a token and identify digital content items corresponding to the token. The digital content system can further provide a new or modified gallery within the view area of the graphical user interface based on the identified digital content items.
