Abstract: Salient sampling for query size estimation includes identifying two or more columns in a database table that have corresponding columns in one or more other tables. One or more hash functions are applied to domains of each of the identified columns. A first hash function is applied to a domain of the first column and a second hash function to a domain of the second column. A subset of the rows in the database table is selected. The selecting includes selecting rows in the database table where results of the first hash function meet a first numeric threshold and selecting rows in the database table where results of the second hash function meet a second numeric threshold. A sample database table corresponding to the database table is created. The sample database table includes the selected subset of the rows in the database table.

Abstract: According to an example, intent and bot based query guidance may include receiving a query associated with a domain, and identifying, based on an analysis of the query, an intent of the query by extracting an action associated with the query and an entity associated with the query. An intent model associated with the query may be generated based on a mapping of the action and the entity with a domain model of the domain. An intent domain specific language representation of the intent model associated with the query may be generated. Based on an analysis of the intent domain specific language representation, a plurality of bots may be identified, and a parameterized bot chain may be generated to respond to the query. A runtime binding of bots of the parameterized bot chain may be performed, and invoked to generate the response to the query.

Abstract: A method and system is disclosed that identifies a job written in a first language. The job is to be performed in parallel on a plurality of nodes of a plurality of clusters. The first language describes functions supported by multiple frameworks but is not specific to any of the multiple frameworks. The method and system select one or more clusters from the plurality of clusters to run the job. The selected one or more clusters of the plurality of clusters operate a different framework from other clusters of the plurality of clusters. The method and system identify a second language associated with the selected one or more clusters. The method and system convert the first language of the job into the second language and cause the job in the second language to be run on the plurality of nodes of the selected one or more clusters.

In some embodiments, systems for managing an in-memory NoSQL database are provided, the systems comprising a hardware processor that is configured to: identify a group of keys capable of being included in a complex multi-key database command, the group including a first key and a second key, the first key being associated with a first value and the second key being associated with a second value, the first value and the second value being stored on different servers that are part of the database; and cause the first value and the second value to be both stored on a given server.

Abstract: A method for use with a garbage collector to provide garbage collection is disclosed. The garbage collection is a concurrent garbage collection provided in a dedicated thread concurrently running in a computing device with a mutator thread. The concurrent garbage collection is triggered based on a dynamically tunable parameter from a previous garbage collection in closed loop feedback.

Abstract: A computing device includes an interface configured to interface and communicate with a dispersed storage network (DSN), a memory that stores operational instructions, and processing circuitry operably coupled to the interface and to the memory. The computing device obtains a data identifier associated with a data object and determines DSN address(es) associated with storage of one or more encoded data slice(s) (EDS(s)). The computing device selects slice names based on the DSN address(es) and issues at least a read threshold number of read slice requests using slice names to at least some storage units (SUs). When an insufficient number of EDSs is received, the computing device issues an alternate read slice request to an alternate SU. When a sufficient number of EDSs is received from the alternate SU and the computing device has received at least the read threshold number of EDSs, the computing device reconstructs the data segment.

Abstract: A very efficient computer system is presented to generate all pairs of records that have a certain similarity. Similarity is defined in terms of the textual similarity of the record attributes and/or absolute difference for numeric record attributes. Software assigns each record to a number of bins, and then compares pairs of records that belong to the same bin. This is more efficient than comparing all pairs of records since the number of records compared to each other is much smaller.

Abstract: A system and method for improving operation of power systems using global filtering criteria across multiple reports or dashboards is provided herein. The system and method may receive data regarding electric power system components, along with a filter selection from a power system operator. The operator's filter selection is applied to the received data, and a first summary is generated. Upon receiving a request to generate a second summary, the system and method apply the filters to the received data to generate a second summary without requiring additional filter selection. The power system operator may then use the generated data in operating the power system.

Abstract: Some embodiments provide a program that identifies an entity having an entity attribute. The program receives, from each method of several methods, a set of candidate identity attributes that are each for identifying a particular entity having the entity attribute specified in the document. Each method of the several methods generates the corresponding set of candidate identity attributes based on the entity attribute specified in a document. The program calculates a score for each candidate identity attribute in the sets of candidate identity attributes. The program identifies, based on the sets of scores, an identity attribute from the sets of candidate identity attributes that identifies the entity having the entity attribute specified in the document.

Abstract: This disclosure relates to personalized and dynamic server-side searching techniques for encrypted data. Current so-called ‘zero-knowledge’ privacy systems (i.e., systems where the server has ‘zero-knowledge’ about the client data that it is storing) utilize servers that hold encrypted data without the decryption keys necessary to decrypt, index, and/or re-encrypt the data. As such, the servers are not able to perform any kind of meaningful server-side search process, as it would require access to the underlying decrypted data. Therefore, such prior art ‘zero-knowledge’ privacy systems provide a limited ability for a user to search through a large dataset of encrypted documents to find critical information.

Abstract: Systems, methods, and non-transitory computer readable media are configured to provide a first element in an interface presentable to a user through which a plurality of ephemeral media content items are accessible by the user for a selected period of time. A second element in the interface through which a plurality of non-ephemeral media content items are accessible by the user is provided.

Abstract: The present disclosure relates to dynamically merging database tables according to user specified parameters. A user may specify a threshold confidence level that relates to a likelihood that two database records represent the same real-world entity. In addition, a user may specify a merge rule such as desired fields or a manner for consolidating the variations of the information in desired fields from the related records. The original database tables are preserved so that users can iteratively create new dynamically merged database tables by varying the parameters.

Abstract: Transparent file processing is supported in Unix-like operating systems by emulating the desired file processing through a number of recipes that accommodate different contexts. Recipes are provided, for example, for local folders in user space, for whole devices (e.g., flash drives or network drives), and for folders synchronized to cloud data. By detecting the path type for a file operation and selecting and applying the appropriate recipe, file processing can be performed in a manner transparent to the user.
