Abstract: Methods and apparatus are provided for serializing data. A computing device can generate a serialization buffer (SB). The SB can specify fields storing data and corresponding offsets, with an offset referring to a location in the SB storing the corresponding field. The SB can access a designated field in the SB by determining a designated offset for the designated field, determining a starting location based on the designated offset, and accessing data at the starting location. A distinct copy of the SB can be stored on a storage device.

Abstract: An online data fusion system receives a query, probes a first source for an answer to the query, returns the answer from the first source, refreshes the answer while probing an additional source, and applies fusion techniques on data associated with an answer that is retrieved from the additional source. For each retrieved answer, the online data fusion system computes the probability that the answer is correct and stops retrieving data for the answer after gaining enough confidence that data retrieved from the unprocessed sources are unlikely to change the answer. The online data fusion system returns correct answers and terminates probing additional sources in an expeditious manner without sacrificing the quality of the answers.

Abstract: Various embodiments provide systems, computer program products and computer implemented methods. Some embodiments include a method of updating an expert corpus set, including obtaining a query from a user, obtaining a raw data source, determining a relevance score for the raw data source with respect to the query, by performing actions including creating a first vector of statistical variables for the query using at least one natural language processing (NLP) socket, the statistical variables having category types, creating a second vector for the first raw data source, having category types that are the same as those for the query and generating a hypothesis regarding the relevance of the raw data source, testing the hypothesis by comparing relative statistical variables, calculating a gradient between the vectors to determine the relevance score and updating the expert corpus set with the raw data in response to the relevance score exceeds a threshold.

Abstract: According to one embodiment of the present invention, a system determines key relationships between database tables and includes a computer system including at least one processor. The system determines a sampling range for one or more matching columns between first and second database tables. The matching columns satisfy one or more matching criteria and the sampling range is based on quantities of distinct values within the matching columns. Data is sampled from the first and second database tables in accordance with the sampling ranges to determine a sample set. Keys between the first and second database tables are determined based on matching between columns within the sample set. Embodiments of the present invention further include a method and computer program product for determining key relationships between database tables in substantially the same manner described above.

Abstract: A device receives a conflicted file, with a structured data format, that includes a conflict marker that does not comply with the structured data format. The conflict marker identifies first edited information and second edited information included in the conflicted file. The first edited information and the second edited information comply with the structured data format, and include information that has been modified in different versions of a shared file to create the conflicted file. The device detects that the conflicted file includes the conflict marker, and identifies, based on the detected conflict marker, the first edited information and the second edited information. The device determines that at least one of the first edited information or the second edited information is to be provided to the application for processing, and provides, based on the determining, the first edited information or the second edited information to the application for processing.

Abstract: Data conversion algorithms such as compression and decompression algorithms or encryption and decryption algorithms are registered in a shared data store for selective use on data by creating implementations of a plurality of functions that as a group characterize the algorithms, converting the implementations to executable code and storing the code in a shared library, and creating and registering data store objects in a data store catalog with a common identifier that enables the algorithm to be selectively called and applied to data.

Abstract: A hosted storage system includes a namespace that contains object identifiers. A first object containing a first data component is stored. A first object identifier in the namespace uniquely identifies the first object. A second object containing a second data component is stored. A second object identifier in the namespace uniquely identifies the second object. A compose object request that designating the first object identifier, the second object identifier, and a third object identifier in the namespace is received. A third object that includes the first data component and the second data component without duplicating the first data component and the second data component is created. The third object identifier is associated with the third object such that the third object identifier uniquely identifies the third object.

Abstract: A database system maintains a feature set of a modern database system while operating directly on raw data files. Systems may use an adaptive indexing mechanism that maintains positional information to provide efficient access to raw data files, a flexible caching structure, and techniques for selective parsing and selective tokenizing. In doing so, possible performance bottlenecks associated with repeated parsing, tokenizing, and expensive data type conversion costs can be overcome.

Abstract: Text input that is automatically “corrected” by an auto-correction process can be analyzed to determine whether to also include text as input before the correction. A set of words particular to an environment can be run through a number of auto-correct processes to determine which words are likely to be corrected, as well as the corrected versions. These “corrected” versions can be added to an index or other collection as synonyms, or alternatives, for the uncorrected words. When a request or other input is received that includes a corrected term, a determination can be made as to whether to include content for the synonymous uncorrected term. Such an approach can enable a user to obtain content that is more likely of interest to the user based at least in part upon known corrections made to terms that did not necessarily need correcting.

Abstract: A method and apparatus are implemented in one or more processors for processing various social media data received over a network for collection, analysis, and application to business logic and/or business applications. Based on personally identifying information of an account holder, social media data regarding the account holder is retrieved from one or more social media sources or a clearing house over the network. The retrieved social media data is processed (i.e., parsed and/or filtered, and validated) via certain criteria. A usefulness score for the social media data is computed based on various factors including at least one of an identity match value, a truth confidence value, and a context data relevance value. The social media data and its computed usefulness score can be presented to a user and business applications for further processing and treatment of the account holder.

Abstract: Backup data is processed by obtaining a set of metadata associated with backup data. A locality-sensitive hash key is generated for the backup data based at least in part on the set of metadata. The backup data is assigned to one of a plurality of deduplication nodes based at least in part on the locality-sensitive hash key.
