Abstract: Technologies are provided for synchronizing and joining multiple calls from a first thread and one or more second threads to execute a particular code segment. In response to a call from the first thread to execute the particular code segment, a task synchronizer module calls the particular code segment on behalf of the first thread. When execution of the particular code segment starts, and a call is received from a second thread to execute the particular code segment after receiving the call from the first thread, the task synchronizer module suspends execution of the particular code segment in response to the call from the second thread so that the second thread awaits for the execution of the particular code segment on behalf of the first thread to complete. When execution of the particular code segment completes, a result value or exception is stored in a task object, and the second thread can read the result value or the exception that is stored in the task object.

Abstract: Methods and systems are provided for implementing session synchronization to synchronize applications at different user systems (e.g., mobile device, laptop, desktop, tablet) of a particular user. As will be explained in greater detail below, this platform level solution that can maintain session information received any number of different user systems of the particular user and share this collective session information with each of the other user systems as session-synchronization information that can be used, at any user system of that user, to ensure that when that user switches from using one user system to another user system that that applications at the “new” user system being switched to are synchronized with any other applications that were most recently in use at all of the other user systems of that user.

Abstract: In some database systems, a user device may query for data records using a procedural language extension to structured query language (PL/SQL) call. However, some databases may not be configured to process PL/SQL code. In these cases, a virtual machine may intercept the PL/SQL call, and may transform the call to a format usable by the database. For example, the virtual machine may deconstruct the PL/SQL call to determine the procedural and query functions that comprise the PL/SQL call. The virtual machine may then search a database for non-PL/SQL code snippets that correspond to these determined functions, and may generate non-PL/SQL code (e.g., Java code) that may perform the same functions as the PL/SQL call. The virtual machine, the database, or a combination of the two may execute the non-PL/SQL code to retrieve the data records from the database, and may return the records to the user device.

Abstract: An ID service provisioned on a server interacts with a corresponding ID app installed on a user device such as a smart phone for secure user authentication (login). A user acquires two asymmetric encryption keys pairs. One of the private keys is secured on SIM on the user device, and the other one stored in the ID app on the user device. At login attempt, the ID service generates two random challenge messages, and encrypts each of them with one of the public keys. Decryption of one challenge is conducted by the SIM and decryption of the other is done by the ID app. A token based on the two decrypted challenge results is returned to the ID service. Alternatively, a single challenge can be double-wrapped with the two keys. The verifies the results and enables secure login without requiring a password.

Abstract: Navigation of a data extraction graph is described. The data extraction graph may be a graph representation of data and metadata in an object-oriented database. In one example, a data extraction definition of metadata from a database system is presented in a graph format. The graph format is transformed into a linear object tree, and/or an object list. Navigation commands are received from a user to navigate the transformed graph format. Selections of objects are received from the user to select objects in the transformed graph format. A summary view of the selected objects is then provided in the transformed graph format.

Abstract: Identifying entities in semi-structured content is described. A system assigns a corresponding entity type based on a corresponding entity type score for each token in a sequence of tokens in semi-structured content, based on multiple entity types, wherein each token is a corresponding character set. The system assigns a corresponding boundary type based on a corresponding boundary type score for each token in the sequence of tokens, based on a begin boundary type or a continue boundary type. The system identifies an entity based on a corresponding entity type score and a corresponding boundary type for each token in the sequence of tokens. The system outputs the sequence of tokens as an identified set of entities based on the identified entity.

Abstract: Contact recommendations based on purchase history are described. A system creates a directed graph of nodes in which at least some of the nodes are connected by directed arcs, wherein a directed arc from a first node to a second node represents a conditional probability that previous users who purchased a first contact also purchased a second contact. The system identifies a set of contacts purchased by a current user. The system estimates a prospective purchase probability based on a historical probability that previous users purchased a specific contact and a related probability that previous users who purchased the specific contact also purchased a contact in the set of contacts, for each candidate contact. The system outputs a recommendation for the current user to purchase a recommended candidate contact based on a corresponding prospective purchase probability.

Abstract: Systems and methods provide multi-version concurrency control of database records with uncommitted transactions. The system and methods may include receiving a query regarding a transaction counter number. When a transaction header identifying data is updated with the assigned transaction counter number, the updated transaction header may be used in identifying data as an instance of multiversion concurrency control information by the received query. A key lookup may be performed, and when the key lookup encounters an uncommitted row for a transaction number, a corresponding transaction header identifying data to identify a data array element to determine whether the transaction number is committed, and determining the transaction counter number when the transaction number is committed. The transaction counter number may be stamped on the row version record when it is determined that the row is committed.

Abstract: Some external users in a public on-line community may post excessive numbers of items, causing annoyance to others and unnecessary loading on database resources. A robust moderation framework enables an individual community moderator or admin to specify a set of rules and actions to mitigate this problem. Scalable, performant rate limiting rules employ windowed counters, separately for each rule, with the counters maintained in cache memory resources outside the main database.

Abstract: A computer system generates augmented training datasets to train neural network models. The computer system receives an initial training dataset comprising images for training a neural network model, and generates an augmented training dataset by modifying images from the first training dataset. The computer system identifies a representation of a target object against a background from the initial training dataset and extracts a portion of the image displaying the target object. The computer system generates samples for including in the augmented training dataset based on the image. For example, new images may be obtained by performing transformations on the portion of the image displaying the target object and/or by overlaying the transformed portion of the image over a different background. The modified images are included in the augmented training dataset used for training the neural network model to recognize the target object.

Abstract: A conversation tool may display messages posted on a social media website. The conversation tool may receive selections of posts from the user interface to send associated reply messages and assign metadata for the selected posts to the associated reply messages. The conversation tool then may receive a request to display a conversation for a particular user. The conversation tool identifies the reply messages with assigned metadata associated with the user and identifies the posts associated with the identified reply messages. The conversation tool displays the identified posts with the identified reply messages as the message conversation. The conversation tool uses the reply messages as a trigger for identifying and tracking conversations between an agent and different users. The conversations allow the agent to more efficiently respond to and manage non-structured messages posted on social media websites.

Abstract: A user of an application can affect the control structure of an application by changing a level of detail setting. When a level of detail is altered relative to a graphical region, additional information and functionality may become available, while previously displayed information and/or functionality for a different graphical region may become hidden or otherwise unavailable. A user may repeatedly enhance a level of detail at which a particular application region is shown by repeatedly using an appropriate user input command. The present disclosure does not simply change a user's view of an application, but changes the way the application itself functions in various embodiments when a level of detail is altered for a graphical region. Techniques described herein may apply to a web application, or to any other suitable computer application.
