Abstract: In a data processing method, storage instance mapping information is obtained based on database configuration information of a blockchain node. The storage instance mapping information indicates data mapping relationships between a plurality of database instances and data types of the plurality of database instances. At least one candidate database instance is determined from the plurality of database instances when to-be-stored blockchain data is received. The data type of each of the at least one candidate database instances is matched with a data type of the blockchain data. The blockchain data is stored to a first database instance of the at least one candidate database instance based on a data sharding strategy in the database configuration information.

Abstract: Methods and systems are provided herein for playing back indexed conversations based on the presence of other people. When a user asks a query, the system monitors the area, determines the other users in the area, and searches its database for a conversation that addresses the query in consideration of the other users present in the area. The system filters the indexed conversations to find conversations that included all the users present and determines the best matching conversation based on the words of the query as well as the keywords from the conversation. Once the system has determined the best match conversation, the system plays back the conversation to the user.

Abstract: Embodiments of this application provide a differential file restoration method and an electronic device. In the method, a differential file includes at least one group of data compressed blocks, and data compressed blocks in each group are divided based on a preset block size before being compressed. When the electronic device performs restoration on the differential file, the electronic device first determines a parallel quantity k of restoration threads based on the block size and a size of RAM space, and then performs restoration processing on the differential file in parallel by using the k restoration threads, where each restoration thread performs restoration processing on the at least one group of data compressed blocks by using one group of RAM space corresponding to the restoration thread.

Abstract: Systems and methods for decoupling information into multiple levels of detail based on semantics while providing a compact global representation structure. A tree-based graph represents objects in an environment. The top node provides complete environment information at the lowest level of detail. Leaves of the tree-based graph complement the parent nodes with more detailed local information. This achieved efficient processing, communication, and data compaction. Steps for updating the tree-based graph are performed at both a far-edge node and a near-edge node.

In one embodiment, the real index is used in an offset query type in order to reduce the number of rows that are sorted and thereby increases efficiency for processing offset query types. In another embodiment, the real index is used in a set operation query type where existing systems utilize a table scan and thereby increases efficiency of set operation query types.

Abstract: A facility for managing information about document-related activities is described. In some cases, the facility uses particular kinds of structures to represent, in a document graph, document-related activities performed by particular users. In some cases, the facility uses these structures to enable one user to subscribe to the document-related activities performed by another user. In some cases, the facility uses these structures to aggregate document-related activities performed by users in a group of users, such as by aggregating topics that are addressed by documents that are the subject of these document-related activities. In some cases, the facility uses particular kinds of structures to represent, in a document graph, tasks that certain users either can help with or need help with. In some cases, the facility uses these structures to match users that can help with a task with users that need help with a task.

Abstract: Systems and methods described herein relate to the prediction of effects of data purging on data sources that are related through hierarchical data relationships. A purge request comprises a set of purge parameters that identify a data source and define one or more purge criteria for purging of data items of the data source. A plurality of impacted data sources is identified based on one or more hierarchical data relationships held by the data items of the data source. The impacted data sources include the data source and one or more additional data sources. The purge parameters are provided to a machine learning model to obtain output indicative of a predicted effect of execution of the purge request on the impacted data sources. The predicted effect is caused to be presented at the user device prior to the execution of the purge request.

Abstract: Disclosed are systems and method of mapping data entries originating in different systems. A plurality of data entries from different systems are normalized such that they can be compared to each other and mapped, even though the data entries are defined by data fields with differing phrases, descriptive details, and lengths of detail. Data entries may be filtered according to data fields before a mapping operation is employed for mapping. The mapping operation evaluates similarity scores based on the data fields using a combination of exact matching algorithms, dictionary matching algorithms, and text mining algorithms. The mapped data entries and data fields are displayed to a user.

Abstract: Modern industrial processes demand flexibility in terms of how data flows are structured in an automation pyramid. Instead of only upward and downward flows, the data should be accessible directly at each level of the pyramid. A gateway for facilitating an integration of process equipment within an industrial environment supporting an open industry standard is provided. Integration of field devices having characteristics, capabilities, and/or requirements that are expressed by a description language for industrial process equipment such as EDDL, into a contemporary communication environment enabling a direct data access, is supported. The communication environment is operated based on a semantically enriched and graph-based data information model such as provided by OPC UA.
