Abstract: Text input data may be aggregated and mapped to create composite text input data for electronic records. A semantic event may be automatically detected, triggered by a semantic rule and associated semantic tag. The detected semantic event may be flagged, and a text mining result database may be updated by adding an entry to the database. An indication associated with the event may be transmitted, and a back-end application computer server may establish a hierarchy for multiple elements of the electronic records. The computer server may determine a weight variable and response variable for each element in the hierarchy and apply a hierarchical credibility weighting methodology to the elements from level 1, representing the least granular level in the hierarchy, to level n, representing the most granular level in the hierarchy, calculated recursively from level n, to determine a final estimated credibility for the electronic records.

Abstract: Disclosed are various embodiments for discovering availability of digital media titles from multiple digital media service providers. In one embodiment, information is obtained about a relationship between a user account and a first digital media service provider. A request for availability of a digital media title is obtained via a user interface. An availability is determined for access by the user account of the digital media title from the first digital media service provider having the relationship with the user account and a second digital media service provider. An indication of the availability for access of the digital media title by the user account is presented.

Abstract: Trace data is received for a first execution of a first query on first tables having first data values. Second data values are generated for second tables from the trace data and without accessing the first data values. The second data values are configured to reproduce, by a second execution of a second query, the evaluation states from the first execution. Evaluation states from the first execution are reproduced without accessing the first data values by performing the second execution of the second query on the second data values. The first execution evaluates only a first subset of the first data values and the generating the second data values from the trace data generates second data values corresponding to the first subset. The second execution only evaluates ones of the second data values that correspond to data values of the first subset.

Abstract: Trace data is received that was captured for an execution of a query on first tables when execution trouble occurs during an execution of the query on the first tables. Trace data includes counts of evaluation states caused by the execution and includes identifications of portions of the query that reference variables of the first tables and that correspond with the evaluation states. Second tables are generated from the evaluation state counts and the identifications of the trace data without accessing data values of the first tables, so that the first tables are kept private. Evaluation states are reproduced from the execution of the query on the first tables by executing the query on the second tables without accessing the data values of the first tables.

Abstract: A method for dynamically detecting and converting a context-sensitive information in a first language and a first format to a second language and a second format that is understandable to an end user based on a user-specified setting is provided. The method may use a built-in camera of a computing device to dynamically detect and capture an image frame of context-sensitive information. The method may use Optical character recognition (OCR), as well as contextual information such as GPS data available from a mobile computing device, to automatically translate and reformat the context-sensitive information in real-time so a user may understand it unambiguously.

Abstract: In an example embodiment, a proxy object is delivered to a first schema having a first logical name and stored in the software object database, the proxy object referencing an object in a second schema having a second logical name. Any dependencies from the object in the second schema to the proxy object in the first schema are removed a cycle-free graph of dependencies between objects the software object database is generated. Objects are delivered the software object database using the cycle-free graph. A definition for the proxy object is created including the logical name for the first schema. The proxy object is delivered by replacing, at a time subsequent to the proxy object being delivered to the software object database, the logical name for the first schema stored in the definition with a physical name for the first schema.

Abstract: Techniques are described for identifying changes to databases. In one example, a table associated with a data set is identified containing at least one entry, each entry associated with a sequence column value. The sequence column value for new entries is automatically incremented by one from a last max value. At time T1, a total entry count and a maximum sequence column value of the entries is calculated and stored in metadata. At time T2 later than T1, a total entry count and a maximum sequence column value in the table is calculated and compared to the previously stored values. If the values are the same, the table has not changed; if the values are different, then a change has been made. In response to a determined change, the calculated total entry count and the maximum sequence column value at T2 is stored in the metadata.

Abstract: High performance query processing and data analytics can be performed across architecturally diverse scales, such as single core, multi-core and/or multi-nodes. The high performance query processing and data analytics can include a separation of query computation, keying data, and data movement and parallel computation, thereby enhancing the capabilities of the query processing and data analytics, while allowing the specification of complex forms of data parallel computation that may execute across real-time and offline. The decoupling of data movement and parallel computation, as described herein can improve query processing and data analytics speed, can provide for the optimization of searches in a plurality of computing environments, and can provide the ability to search through a larger space of execution plans.

Abstract: Implementations relate to content data determination, transmission, and storage for local devices. In some implementations, a computer-implemented method includes determining an event for a user based on user data associated with the user, and includes programmatically analyzing the user data having one or more references to at least one of persons, locations, and scheduled activities. The method determines a set of content items to be accessed at the event, where one or more content items of the set are determined based on the user data, and the set of content items includes content data related to the event. Prior to a time of the event, the set of content items are transmitted over a communication network from network storage to local device(s) associated with the user, where the content items are stored in local storage of the local device(s).
