A computer-implemented method for identifying an expression for a target concept, includes: obtaining a set of texts as a target set of texts, with each text being associated with one of images relevant to a target concept. Candidate expressions for the target concept are extracted from the target set of texts. The candidate expressions are characteristic of the target set of texts. Each image relevant to one of the candidate expressions is collected by using an image search engine. A target expression for the target concept is selected from the candidate expressions based on a comparison result of the target concept and the collected images. |

Efficient spatial queries in large data tables
The present disclosure relates to a method for processing data blocks of a data table. The data blocks comprise an attribute representing multidimensional spatial data objects, where the attribute has multiple values representing respective dimensions of the multidimensional spatial data object. The method comprises creating for each data block of the data blocks, a respective attribute metadata. The attribute metadata comprises attribute value information defining a multidimensional minimum bounding rectangle that covers attribute values of the attribute comprised in the data block. A query is processed on the multidimensional spatial data objects associated with a query area using the multidimensional minimum bounding rectangle to check whether a data block of the data blocks contains attribute values of the attribute in the query area. |

Asynchronous notifications for a datastore of a distributed system
The data of an online system is distributed over a number of different physical servers and databases on those servers. The online system shards the data to increase system scalability and replicates the shards to increase data reliability. Features such as sharding and replication in turn increase data storage system complexity. Accordingly, in order to provide simplified data storage semantics to applications that use the online system, the online system provides access to data via asynchronous callback functions that are triggered once data has been written and is available for reading by client code. Thus, applications need only specify code to be used in response to data write events, and can thereafter interact with the online system data using a data-driven paradigm. |

Database data modification request processing
A data modification request for modifying data in a primary database is received at the primary database. Based on the data modification request, second data in the primary database is modified to first data. Based on the data modification request, a first log and a second log are generated, where the first log is a simplified log including the first data and the second log is a complete log including the second data. Persistence processing is performed on the first log. A modification result that corresponds to the data modification request is returned. |

Generating answer variants based on tables of a corpus
Mechanisms are provided for implementing a candidate answer variant engine. The mechanisms receive an indication of a structured portion of content in a corpus, generate a plurality of groupings of elements of the structured portion of content, and generate, for each grouping of elements in the plurality of groupings of elements, and for each element in the grouping of elements, a corresponding grouping vector representation, corresponding to the element. The mechanisms, for each grouping vector representation of each grouping of elements in the plurality of groupings of elements perform a similarity measure calculation between the grouping vector representation and a vector representation of an input question, and select an element corresponding to the grouping vector representation for inclusion as a candidate answer variant based on results of the similarity measure calculation. The mechanisms perform question answering operations based on an analysis of one or more candidate answer variants. |

Recursive data traversal model
One or more embodiments interpret a configuration graph to efficiently and optimally construct requests and fetch data from a datastore. The values of objects of a requested data type are used to generate additional queries for pre-fetching data from the datastore. Specifically, the values are used to query for and retrieve a corresponding subset of objects of another, related data type. Recursively querying for and retrieving objects of related data types based on already retrieved objects builds a data cache of relevant objects. The cached, relevant objects may be useful in subsequent queries that are likely to follow the initial query. |

Transforming directed acyclic graph shaped sub plans to enable late materialization
A query is received at a database execution engine. A query plan including a sub plan structured as a directed acyclic graph is determined by the database execution engine. A set of trees characterizing the sub plan is generated by the database execution engine and using the directed acyclic graph. The set of trees include a first tree and a second tree, the first tree including at least one leaf characterizing a memory store operation and the second tree including a root characterizing a memory access operation. The set of trees are stored for use in execution of the query at run time. Related systems, methods, and articles of manufacture are also described. |

Query plan based on a data storage relationship
Disclosed aspects include the database management system detecting that a first data storage medium includes a first set of data of a database. The first data storage medium has a first access-factor. The database management system detects that a second data storage medium includes a second set of data of the database. The second data storage medium has a second access-factor which differs from the first access-factor. Based on a data storage relationship, the database management system determines a query plan to access both the first set of data with respect to the first data storage medium and the second set of data with respect to the second data storage medium. The database management system establishes the query plan. |

Range overlap query response system for graph data
A computing system determines a response to a query. A bin start value and a bin stop value is defined for each bin based on an input bin option. End nodes are split based on the bin start value and the bin stop value of each bin to define a second plurality of end nodes. Each start node of a plurality of start nodes that is connected to each end node of the second plurality of end nodes is identified based on the respective link attributes of a plurality of link attributes. Overlapping start nodes of the plurality of start nodes that overlap at an end node of the second plurality of end nodes are identified based on a predefined overlap query graph that defines a connectivity to identify between a start node and the end node. The identified overlapping start nodes are output as a response to the predefined overlap query graph. |

Big-data view integration platform
A big-data view integration platform generates integration guided user interfaces (GUIs). A first edge node ingests push-based and pull-based data from a plurality of platform services, which include legacy and non-legacy services having incompatible communication protocols. An event-based queue receives from the first edge node a plurality of queue events as indirect push-based data. A second set of queue events includes direct push-based data as received directly from a non-legacy platform service. A conformity component integrates the push-based data, the pull-based data, and the plurality of queue events into integration data having an enhanced integration format. A view integration component generates a plurality of data views from the integration data. A second edge node exposes the plurality of data views via an access services application programming interface (API). A new service execution component accesses the access services API to generate integration GUIs based on the data views. |
