Abstract: In connection with processing asynchronous streams of aircraft telemetry data, data processing logic is developed to run on multiple aircraft, even if different avionics equipment are installed on the aircraft. An electronic inventory system tracks data available on affected aircraft. A set of “global” data elements applicable to aircraft in a fleet is defined and is tracked in the electronic inventory system, with relationship to the underlying native data elements and specific aircraft. The global units are derived as appropriate, for each specific aircraft avionics environment. An interface enables definition of data processing logic that is integrated with the electronic inventory system and ensures the general validity of the defined logic. The data processing logic is deployed to one or more aircraft in a function integrated with the electronic inventory system, to ensure the validity of the data processing logic for each aircraft specified as a deployment target.

Abstract: A technique operable in a data storage system performs initialization of storage structures in multiple stages and allows hosts to request access to a data object even when some of the storage structures supporting the data object have not been initialized. Rather than initializing all storage structures for a data object before allowing host access, a storage processor instead initializes only a protocol stub structure. The protocol stub structure is configured to receive protocol requests from hosts and to initiate further processing should a storage request in that protocol be received. The further processing includes, in response to receiving a protocol request directed to a host-accessible data object, identifying storage structures involved in processing that protocol request and directing the storage processor to initialize those storage structures.

Abstract: For online searching, data of a user activity is analyzed where the user activity occurs at an application other than a search application and the search application is used for the online searching. In response to the analyzing, a topic of interest of the user is identified. A search term input is detected at the search application. A subject of the search term is identified. The search term is modified using a modifier. The modifier is a term related to the topic of interest, and the online searching occurs in response to the modified search term.

Abstract: In one embodiment, a method includes receiving, from a client device of a first user, a text string inputted by the first user, generating a set of suggested queries based on the text string, each suggested query in the set being based on a string generated by a grammar of a grammar model and comprising the text string of the query and one or more tokens inserted by the grammar model, calculating, for each suggested query in the set, a quality score based on an insertion cost of the one or more tokens inserted by the grammar model, filtering the set to remove one or more suggested queries from the set based on the respective quality scores of the suggested queries, and sending, to the client device, one or more of the suggested queries from the post-filtered set for presentation to the first user.

Abstract: A computer initializes a configuration specified in an extensible markup language (XML) configuration file. The XML configuration file specifies at least one data source, a dimension to map each item of a plurality of items that include products, product accessories, or product support documents in the at least one data source, and a display priority for each item. Next, the computer reads data from the at least one data source specified in the configuration file. The computer generates an XML dimension hierarchy file for the read data using the configuration file. The XML dimension hierarchy file includes a dimension node for each item. Each dimension node has at least one property attached to each item and at least one synonym that is searchable to index each item. Finally, the computer preprocesses the XML dimension hierarchy file to index the at least one data source.

Abstract: Architecture that splits the generation of results summaries into at least two phases for reduced latency and improved relevance. A first phase generates a summary quickly and thereby enables subsequent modules to begin processing. A second round then executes in parallel to these other modules to offset the latency. The second round can also provide additional contextual information to the summarization module to improve the quality (relevance) of the summaries. Ultimately, the summaries generated in the two phases are merged. The multiple rounds of summarization enable the first round to be cheaper in processing resources to save overall latency, whereas the second phase can be more expensive, since the second phase can be run in parallel with other modules. Additionally, contextual information can be used to build the full content summaries in the second round.

Abstract: Methods and systems are provided for regulating access to a database by a server. One exemplary method involves the server receiving one or more requests for an activity with respect to the database and determining an attempted usage for the activity over a monitoring period by a source of the requests. When the attempted usage exceeds an allowed usage of the activity for the monitoring period, the server creates an entry in a cache that includes an identifier associated with the source of the one or more requests. Thereafter, the requested activity with respect to the database on behalf of the source may be prevented based on the entry in the cache.

Abstract: A content management system synchronizes content items across client computing systems connected by a network. If a storage allocation for shared content items on a client device is exceeded by the request to add or edit a content item such that it is enlarged, a client application or the host of content management system selects content items to remove from residence on the client device but keep remotely on content management system. Upon removal of the selected content items, the client application creates shadow items, representing the content item but only containing the metadata of the content item. This creates sufficient space while maintaining user access to all synchronized shared content items. Entries in a file journal may be used to track and manage whether a stored item is a content item or a shadow item.
