Abstract: Computer-implemented techniques for sematic image retrieval. According to one technique, digital images are classified into N number of categories based on their visual content. The classification provides a set of N-dimensional image vectors for the digital images. Each image vector contains up to N number of probability values for up to N number of corresponding categories. An N-dimensional image match vector is generated that projects an input keyword query into the vector space of the set of image vectors by computing the vector similarities between a word vector for the input query and a word vector for each of the N number of categories. Vector similarities between the image match vectors and the set of image vectors can be computed to determine images semantically relevant to the input query.

Abstract: The present technology pertains to a organization directory hosted by a synchronized content management system. The corporate directory can provide access to user accounts for all members of the organization to all content items in the organization directory on the respective file systems of the members' client devices. Members can reach any content item at the same path as other members relative to the organization directory root on their respective client device. In some embodiments novel access permissions are granted to maintain path consistency.

Abstract: The present disclosure is directed toward systems and methods that efficiently and effectively identify experts relative to a key topic within an organization. For example, systems and methods described herein can receive an expert assistance query from a user looking for an expert associated with a particular topic. Systems and methods described herein can further apply a trained expert selection model to a key topic extracted from the received expert assistance query. In response to receiving an identified expert from the expert selection model, systems and methods can further identify and provide information associated with the identified expert such as the expert's contact information, the expert's team information, and other data (e.g., documents, emails, communications) authored by the expert in association with the key topic.

Abstract: Inline content item editor commands are provided. An implementation allows a user to initiate various functions related to a content item being edited by entering a command expression inline with the content of the content item being edited. The manner of editor function initiation saves the user time and effort and reduces cognitive burden on the user because it does not require the user to change input modes (e.g., from keyboard to mouse) or change input areas (e.g., from a content item editing area to a distant toolbar or context menu) in order to initiate the function and, if applicable, provide parameters to the function.

Abstract: A content management system including a document management system provides documents that include comments entered by users. Comments are organized into threads; each thread is associated with a span of text in the document. When a user requests access to a document, the document management system determines which threads are visible to the user based on an audience associated with each thread. the audience comprises the user identifiers of i) the author of the document containing the thread; ii) the authors of comments included in the thread; iii) the authors of any text included in the text span for the thread; iv) any user mentioned in the text span the thread via a user primitive; v) any user mentioned in a comment via user primitive.

Abstract: A topology-based monitoring and alerting system is disclosed. Streams of metric time series values emitted by computing nodes in a distributed computing system that are relevant to the queries are aggregated in query caches in a historically accurate manner. Submissions of the queries for progressing time periods are answered from the query caches with historically accurate query results. Because streamed metric time series values are pre-aggregated in the query caches prior to a submission of a query for a time period, the submission can be answered with computational efficiently from the query cache established for the query while providing a historically accurate query result.

Abstract: One or more embodiments of a thumbnail caching system dynamically provide a thumbnail cache of digital content items (e.g., photos, videos, audio) to a user on a client device. In particular, the thumbnail caching system provides a thumbnail cache of a digital content collection to a client device such that the thumbnail cache does not exceed a threshold storage limit for the client device. In addition, the thumbnail caching system intelligently adjusts the thumbnails within the thumbnail cache to keep the size of the thumbnail cache within the threshold storage limit irrespective of the number of digital content items stored or added to the digital content collection. Further, the thumbnail caching system can dynamically adjust the size of the thumbnail cache in response to a user adding or removing external data to the client device.

Abstract: A computing system generates a default view of content items associated with a user account. The default view is representative of an underlying hierarchical structure of the content items associated with the user account. The computing system receives a request to transition from the default view to a modified view of the content items. The computing system ranks the content items based on a predicted likelihood of the user interacting with the particular content item. The computing system identifies the subset of content items for the modified view based on the ranking. The computing system generates the modified view based on the identified subset of the content items. The modified view maintains the underlying hierarchical structure of the content items associated with the user account. The computing system provides the modified view to the user associated with the user account for display.

Abstract: A user interface for a messaging client application can include a message list. By executing various input operations on a representation of a message in the message list, the user can take an action on the message. For example, a user operating a pointing device can perform a drag operation on a representation of the message in the message list, and the action to be taken on the message can be indicated by the direction and distance of the drag. Visual feedback can be provided during the drag operation to indicate the action that will be taken if the user ends the drag at the current location.
