Abstract: Various embodiments of systems, computer program products, and methods to assess translation quality are described herein. In an aspect, a translated text is received during translation of content from a source language to a target language. The received translated text is detected as an incorrect translation by analyzing a number of quality checks in a translation quality algorithm. An error category corresponding to the incorrect translation is determined based on a root cause of the incorrect translation. Further, a counter is incremented in a corresponding error category. When the counter exceeds a threshold, an action to prevent submission of the translation is triggered based on a combined error score. The combined error score is a combined weighted error score from error categories which have exceeded their respective thresholds.

Abstract: String comparison, including comparing strings with a rule, can be time consuming, and strings may not be suitable for analysis using machine learning algorithms. The present disclosure provides positionally-encoded representations of strings, such as binary matrices or arrays, that provide an encoded representation of the string. The encoding, and decoding, can be facilitated by an encoding schema, such as an encoding schema stored in the memory of a computer device. The encoding schema associates particular characters with particular positions in an array. The positionally-encoded string representations can be used for security applications, such as to determine whether an authorization token that includes at least one string complies with an authorization rule. The authorization rule can be specified as a positionally-encoded representation that defines a set of strings that comply with the rule.

Abstract: Technologies are described for performing synchronization within a database environment. A source host stores multiple database tables and a replica host stores copies of the multiple database tables. During synchronization, replication log replay is blocked at the replica node, and a multithreaded process locks the multiple database tables of the source hosts, reactivates replication log generation for each of the multiple database tables, and then unlocks the database tables. A synchronization timestamp is acquired and used to synchronize the multiple database tables with the copies of the multiple database tables. After synchronization, replication log replay is reactivated at the replica host for the copies of the multiple database tables.

Abstract: A communication port may exchange information with a user via a graphical user interface, and an application data store may contain information about executable applications, including input data and output data associated with each executable application. A merging platform may recognize that a user has selected, via the graphical user interface, a first executable application in the application data store. The merging platform may also recognize that the user has selected a second executable application in the application data store and receive an indication from the user that an application merging application is to be triggered. Responsive to this triggering, the merging application may merge behaviors of the first executable application and the second executable application, including functionality of the input and output data of each executable application, to create a merged application. The merging platform may then arrange to facilitate execution of the merged application.
