Embodiments are directed to managing data visualizations. Candidate data fields from a data source may be determined based on a search expression. The candidate data fields may be displayed in the model panel. A working data model may be generated based on a portion of the candidate data fields such that the portion of the candidate data fields may be included in the working data model. Visualizations may be determined based on recommendation models and the working data model such that a portion of the visualizations may be determined based on shared data fields that may be included in the working data model and the visualizations. A working visualization may be determined based on a visualization listed in the display panel and the working data model such that data fields included in the working data model may be associated with the working visualization.

A method for effective vehicle identification and communication between riders of transportation network companies (TNC), and the vehicles that are being designated to the riders. Accordingly, a system used to execute the method of the present invention conveys the information of the rider on a display device on the designated vehicle of the rider, so as to notify the rider before getting into the designated vehicle. Additionally, the present invention also helps assist blind people by conveying audio messages, such as pipe messages or announcing their names. Further, the present invention provides riders the ability to send an emergency alert, thereby ensuring a safer ride. Furthermore, the present invention enables TNCs to utilize the display device as a trade dress and as an optional platform for other media advertisements.

An automated method for search includes: receiving search characters and a viewport location on a displayed geographic area corresponding to an area of interest; simultaneously searching a first entry source and a second entry source to obtain corresponding first suggested entries and second suggested entries, where the first suggested entries correspond to geographic locations that are closer to the viewport location; ranking the first suggested entries according to first rules of relevancy, and generating first ranked suggested entries; ranking the second suggested entries according to second rules of relevancy, and generating second ranked suggested entries; combining the first and second ranked suggested entries into a combined set of suggested entries, and ranking the combined set of suggested entries according to combined rules of relevancy, and generating combined ranked suggested entries; and transmitting the combined ranked suggested entries to a user for selection of a desired type ahead entry.

A laboratory system for analyzing biological samples is presented. The laboratory system comprises a plurality of laboratory instruments configured to receive and identify biological samples and to query a laboratory control unit for a processing order indicative of processing steps to be carried out on the biological sample. The laboratory control unit is configured to validate sequence of queries from the plurality of laboratory instruments against a valid query sequence pattern.

The present application discloses a method, an apparatus, a device, and a storage medium for intention recommendation, which relates to the field of big data, artificial intelligence, intelligent search, information flow and deep learning technologies in the field of computer technologies. A specific implementation scheme includes: receiving an intention query request carrying an intention keyword and a user identification, determining a first recommendation list according to the intention keyword and a pre-configured intention repository, where the intention repository includes at least one tree-shaped intention set, and each tree-shaped intention set includes at least one graded intention, processing intentions in the first recommendation list by using intention strategy information corresponding to the user identification to obtain a target recommendation list and output it.

A method may include responding to a query to retrieve data from a database by identifying a plurality of query execution plans. An overall robustness value may be determined for each query execution plan. The overall robustness value of a query execution plan may correspond to a sum of individual robustness values for each operator included in the query execution plan. Each operator may have an individual robustness value that corresponds to a first change in a total cost of a query execution plan including the operator relative to a second change in an output cardinality of the operator. One of the plurality of query execution plans may be selected based on the overall robustness value of each of the plurality of query execution plans. The query may be executed by performing a sequence of operators included in the selected one of the plurality of query execution plan.

A method and a device for managing a node includes: initiating, by an application program, a first request by calling an interface function, where the first request is used to perform an operation on a feature node in a kernel; searching, based on a keyword of the interface function, a table used for node management for an entry corresponding to the feature node, where the entry includes a node identifier of the feature node and a user handle identifier of the feature node; and performing, by the user program, the operation on the feature node based on the user handle identifier. A program running in user space can be prevented from directly accessing a feature node in kernel space, thereby improving system security.

Method and apparatus for stress management in a searchable data service. The searchable data service may provide a searchable index to a backend data store, and an interface to build and query the searchable index, that enables client applications to search for and retrieve locators for stored entities in the backend data store. Embodiments of the searchable data service may implement a distributed stress management mechanism that may provide functionality including, but not limited to, the automated monitoring of critical resources, analysis of resource usage, and decisions on and performance of actions to keep resource usage within comfort zones. In one embodiment, in response to usage of a particular resource being detected as out of the comfort zone on a node, an action may be performed to transfer at least part of the resource usage for the local resource to another node that provides a similar resource.
