Abstract: A method and server for determining rank positions of non-native items by a ranking system is provided. Native items are rankable by the ranking system and non-native items are non-rankable thereby. The method comprises acquiring user interactions associated with items. Each item is associated with a visual position on a SERP such that the native items and the non-native item are arranged in a visual 2-D arrangement having rows, each row has at least two horizontally-arranged items. The method comprises generating a usefulness score for each non-native item by analyzing user interactions associated with (i) the non-native item, (ii) items being horizontally-arranged after the non-native item and (iii) with items being vertically-arranged after the non-native item. The method comprises training the ranking system to predict a predicted usefulness score. The method also comprises determining an optimal ranked position for a non-native item by the ranking system during an in-use phase.

Abstract: The described technology is generally directed towards recovery of an impacted (damaged) tree in an impacted zone in a geographically distributed data storage environment, using a peer tree in a remote zone. A peer zone is selected for recovery, and updated to have current data. Logic at the impacted zone requests recovery of an impacted tree, identifying one or more recovery ranges for which recovery data is needed. Logic at the peer zone locates missing objects via the peer tree, and provides recovery information to the impacted zone, by which recovery of the impacted tree is able to be accomplished. For example, a replication journal may be returned as a tree recovery journal comprising add leaf (object) instructions, whereby the impacted zone processes the journal with respect to a reduced representation of the impacted tree to obtain a recovered tree.

Abstract: Migration specific action requests to perform a set of migration specific actions are sent from a source system instance to a target system instance. Migration specific action responses are received from the target system instance. Based on the migration specific action responses, traffic lights for resource utilization of the target system instance are determined. Based on the traffic lights, a concurrency limit is determined for the specific time. The concurrency limit is applied to scale a total number of ongoing migration specific actions to be requested of the target system instance at the specific time.

A computing device provides, within the GUI, a polymorphic lookup interface for retrieving a plurality of entity instances to relate to the GUI object. The computing device provides a plurality of types of entities within the polymorphic lookup interface. A type of entity selected from the plurality of types limits the possible entity instances that may be returned. Through the polymorphic lookup interface, the computing device enables a user to select two or more entity instances to relate to the GUI object. Each of the selected entity instances may be selected from a plurality of possible entity instances that are returned, where each possible entity instance is a same type of entity.

Abstract: A composer interface allows a user to provide input, such as text data, to the social networking system. To reduce the number of inputs for a user to provide to the social networking system, one or more phrase objects are presented to the user when providing input. A phrase object includes a group of objects that users have previously provided to the social networking system. The social networking system presents phrase objects to the user that match at least a portion of the received input. Context information associated with the input and associated with various phrase objects may be used to select the presented phrase objects. By selecting a presented phrase object, the user includes the selected phrase object in the input.

Abstract: In an approach, a database management system is configured in a manner that allows all pluggable databases within a cluster to be treated, from the perspective of a user, as though stored on a single container database, even when the pluggable databases are distributed across a plurality of container databases. When a command is received by a database server that is to be executed on all or a subset of the pluggable databases within the cluster, the database inspects mapping information replicated on all container databases within the cluster by a cluster synchronization server to determine which container databases store pluggable databases implicated by the command. The command is then forwarded to the database servers responsible for the determined container databases for execution. As a result, the commands issued by the user can be agnostic in regard to the actual location of the pluggable databases within the cluster.

Abstract: 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.

Abstract: Exemplary embodiments may provide an automated approach for processing an input data sample to yield a set of object classes, a parser and one or more unit tests for input data that is to be integrated into a data lake. The objects may be readily queried and, in some instances, may be Plain Old Java Objects (POJO's). The exemplary embodiments may process an input data sample to better understand the format of the input data. The input sample may be processed to identify entities, such as records, objects or the like, in the input data sample. The input data sample may be processed on a line by line basis to identify fields in the entities. Once the format of the input data is determined from the input data sample, a parser may be generated to parse the input data.

Abstract: A method and system for generating a replacement query for a user-entered query is provided. The user-entered query is received by a service that never used it and is potentially erroneously entered. The method comprises selecting a set of queries for the user-entered query from past queries based on string similarity. The method comprises retrieving past-query-interdependence data indicative of past transitions between each pair of queries in the set of queries. The method comprises selecting an approximated query from the set of queries based on string similarity and usage frequency. The method comprises, for each pair of approximated query and one of the set of queries, generating a vector based on past-query-interdependence data between the approximated query and respective one of the set of queries. Each vector can be used as an approximated vector. The method comprises generating ranking parameters for the approximated vectors and determining the replacement query.

Abstract: A computing device is configured to generate a graphical user interface (GUI) that allows an end-user to search for particular document or documents within a large collection of documents. The GUI provides a view of the overall document collection and affords the end-user the ability to reduce the number of visual document thumbnails by means of keyword search. When the end-user identifies a candidate among the reduced number of thumbnails, the end-user may select the page view of the candidate document and conduct further review. If the selected candidate is not the target document, the end-user may select adjacent documents to seamlessly transition between reading and searching. An advantage to this approach is that the visual qualities of the documents, such as images, graphical layout, and color, among others, may be incorporated into the search process. Searching for a particular target document is, thus, expedited.
