Abstract: A query to retrieve database values for a first subset of table columns in a database table is determined. Runtime column selection variables are set up to identify the first subset of table columns for data retrieval, and are dynamically bound to a prepared query statement with single-column query statements joined by interstitial union operators. Each single-column query statement in the prepared query statement specifies a single-column query directed to a corresponding table column with a corresponding predicate to be bound at runtime dynamically with a corresponding portion of the one or more runtime column selection variables. The predicate is evaluated to be true or false in dependence on whether the corresponding table column is in the first subset of table columns. The prepared query statement is executed to retrieve database values for the first subset of table columns in the database table.

Abstract: An internet question answering method is applied in an internet question answering system. A current-turn user question is received. Based on a discourse labeling model, a discourse of the current-turn user question is labeled as “discourse continue” or “discourse end” online and real-time. Based on the discourse of the current-turn user question, whether to clear at least one discourse of an old boundary is determined. The internet question answering system answers the current-turn user question. A match degree between a next-turn user question and the segment of the dialog log is compared to determine whether the discourse of the current-turn user question is correct, whether to correct the discourse of the current-turn user question, and whether to adjust the discourse labeling model by using the current-turn user question.

Abstract: Techniques are described for dynamically synchronizing applications executed on a client device with backend systems. An example method includes identifying a triggering event associated with a request to perform a synchronization of a client application, where the request is associated with a request for a partial synchronization of the client application. A set of information defining a request context associated with the request is obtained. A set of potential partial synchronization scenarios are identified, where each of the potential partial synchronization scenarios associated with a predefined synchronization context. The request context is compared to the predefined synchronization contexts of the set of potential partial synchronization scenarios to identify a particular partial synchronization scenario corresponding to the request context.

Abstract: Methods and systems for displaying information sets in determined orders are described. The information sets comprise vehicle service information. An order of information set identifiers associated with the information sets is based on vehicle identifying information of a subset of vehicles, and an additional search term comprising a symptom identifier and/or a vehicle component identifier of a component located on the vehicles.

Abstract: Embodiments are described for reducing memory usage and disk I/O's for reading and writing streams in a deduplication storage system. Generations of backups of a stream can be tracked for the stream. In the first generation (first backup), stream data is ingested, segmented, and written to disk without looking up a fingerprint of each segment, to save disk I/O's and memory. After the first generation, an amount of stream data processed is tracked, and at dynamically tunable increments of data processed, a fingerprint index lookup is performed to disk. The fingerprint index is read into memory and subsequent fingerprint lookups are preformed to cache, until a next dynamically tunable fingerprint lookup to disk. The dynamically tunable increment of processed data can be randomly reset.

A sub list of categories is selected, wherein the sub-list comprises those categories in the list that have corresponding distinct correlation scores above a predetermined value. Input data that tends to over correlate to the classification system is received. A truncated snapshot is generated, the truncated snapshot comprising only attributes from the plurality of input attributes that have corresponding input categories that match categories in the sub-list of categories. The data is classified using the truncated snapshot and the classification system.

Abstract: A dataset management system organizes datasets and tracks the changes to the dataset to adaptively respond to user queries. For a dataset, the dataset management system tracks the evolving schema of the dataset over time as new data values and/or updates to existing data values are incorporated into the dataset. When a query is received, the dataset management system accesses the schema of a dataset to understand how the dataset has changed over time. Given the changing schema of the dataset, the dataset management system can respond by providing recommendations as to suggested queries that can return improved results. As another option, the dataset management system can execute a query and return results that satisfy the query to the client device that provided the query.
