Abstract: A method for intelligently evaluating sharing readiness of a document stored on a sharing platform includes determining, for each of multiple versions of the document, a deviation metric quantifying similarity of the version with another consecutively-saved version of the document; evaluating the deviation metrics for the document in view of predefined readiness criteria indicative of sharing readiness; and presenting a sharing recommendation on a user interface of the sharing platform responsive to determining that a subset of the deviation metrics for the document satisfy the predefined readiness criteria.

Abstract: Technology is disclosed for controlling the processing and presentation of group data on computing devices to provide improved computing applications, electronic communications, and user computing experiences. Data indicating a group of people may be programmatically determined or inferred, such as from the user activity of a particular user. Group data characterizing the group of people may be generated and contextualized or personalized for the user based on a user context or intent. Aspects of the contextualized group data may be provided to the user in response to an interaction with an indication of the group or group member. The group data may be provided as a set of group information items, and further may be formatted or assembled for presentation based on the user context, and/or may be consumed by a computing application or service to provide an improved user computing experience.

Abstract: Techniques of dynamic hash function composition for change detection in distributed storage systems are disclosed herein. In one embodiment, a method includes dynamically selecting a hash function for a property of a new version of the document and generating a hash value of the value of the property using the selected hash function. The method can then include determining whether the generated hash value of the property of the received new version is different than that of a previous version of the document in the distributed storage system. In response to determining that the generated hash value is different than that of the previous version of the document, a notification can be transmitted to one or more computing services previously registered to receive a notification regarding a change in the property without transmitting the notification to other computing services not registered to receive the notification.

Abstract: Techniques of property grouping for change detection in distributed storage systems are disclosed herein. In one embodiment, a method includes grouping multiple properties of a document into multiple groups individually including a subset of the multiple properties. For each of the multiple groups, a hash value of the group is generated based on values of the subset of properties in the group. The method further includes determining whether the generated hash value of the group is different than that of a corresponding group in a previous version of the document in the distributed storage system. In response to determining that generated hash value of the group is not different than that of the corresponding group in the previous version, metadata is inserted into the new version of the document indicating that none of the subset of properties in the group has changed.

Abstract: Techniques of granular change detection in distributed storage system are disclosed herein. In one embodiment, a method includes receiving a subset of data representing a new version of a document with multiple properties. The subset of data includes hash values corresponding to the properties of the document. The method further includes for each of the properties, performing a comparison of the hash values in the new version to that of the properties in a previous version of the document. Based on the performed comparison, whether the property has changed in the new version of the document is determined. The method can then include, transmitting a notification to one or more computing services previously registered to receive a notification regarding a change in the identified one of the properties without transmitting the notification to other computing services not registered to receive the notification.

Abstract: The present disclosure relates to a server system or other computer equipment for storing data of a first party and determining whether a second party is permitted access to that data based on metadata associated with the data. The disclosure provides a variety of techniques for reducing latency in a security check operation which involves reading this metadata to determine whether the second party is permitted access.

Abstract: Systems, methods, and software are disclosed herein for implementing enhanced search environments. In one implementation, an enhanced service environment includes a working set service that receives event signals initiated by working set agents in various application services. The working set agents communicate the event signals to nominate events occurring in the application services for inclusion in a working set of information specific to a user. The nominations may be based at least in part on a working set model specific to the user. In response to receiving the event signals, the working set service determines which of the events qualify for inclusion in the working set of information based at least in part on the working set model. For each event that qualifies for inclusion, the working set is modified to include at least the event.

Abstract: Sparse data may be stored in a search index such that one or more data points related to a number of entities may be queriable. Upon detection of a data point related to an entity, an integer array may be created for the data point to store within a single column of the search index, the integer array including an identifier of the entity and a value associated with the data point. In response to receiving a request from a user to perform a query on the search index that includes the data point, the query may be transformed to a corresponding range based on the identifier of the entity. Upon execution of the query, the identifier may be removed and query results may be provided to the user as another array with a user-compatible identifier for the entity such that the results may be understood by the user.

Abstract: In a method for a dynamic updating of an index of a search engine, wherein the index is an inverted index comprising a dictionary, a posting file with a posting list for each keyword of the index and a database log, the documents are inserted in the index in small batches called update generations, a list of all occurrences of keywords in the documents of each update generation is generated, the occurrence list is inserted in the database log, and for each keyword entered in the database a reference to a previous entry of the same keyword is created. This previous entry has a reference stored in the mass storage device as the last added entry of all recently keywords.—A search engine performing the method may be implemented on one or more servers with a mass storage device, and comprises a core search engine with a search subsystem and an indexing subsystem for creating a keyword index stored on the mass storage device and with the index realized as a dynamically updateable index.
