Abstract: The technology disclosed relates to de-duplicating contextually similar news feed items. In particular, it relates to assembling a set of news feed items from a plurality of electronic sources and preprocessing the set to generate normalized news feed items that share common company-name mentions and token occurrences. The normalized news feed items are used to calculate one or more resemblance measures based on a sequence alignment score and/or a hyperlink score. The sequence alignment score determines contextual similarity between news feed item pairs, arranged as sequences, based on a number of matching elements in the news feed item sequences and a number of edit operations, such as insertion, deletion, and substitution, required to match the news feed item sequences. The hyperlink score determines contextual similarity between news feed item pairs by comparing the respective search results retrieved in response to supplying the news feed item pairs to a search engine.

Abstract: To measure usage of computing resources on a computer, a logging service running on the computer generates event data. The computer transmits the event data to an event processing system. With a large number of computers, each computer transmits its event data to the event processing system. The event processing system stores the event data in a storage system as a file system object, such as a stream or file, in which different data fields of the received event data are stored in a structured or semi-structured manner. The event data can be processed in parallel on different pivots using map-reduce operations. Such processing can include, but is not limited to, de-duplicating event data, aggregating event data related to a resource into measurements of usage of that resource, and grouping original data or aggregated data by user or group of user for further analysis and reporting.

Abstract: Systems and methods for model validation includes generating a first and a second time series of segmentation states for a data set representative of a simulated population, e.g., a collection of membership counts corresponding to respective segments of the simulated population. The first and second time series of segmentation states are generated by respectively processing the data set through a first and a second simulation each comprising iterative application of a plurality of event functions. The first and the second simulation differ in at least one capacity, e.g., one including a first event function configured with a first parameter, and the second not. Analysis of differences between the first and second time series may be compared to analysis of one of the time series using a subject model. The comparison is then used to validate the model or demonstrate accuracies, inaccuracies, and/or model bias with respect to a performance metric.

Time series data are sequences of time stamped records occurring in one or more usually continuous streams, representing some type of activity. In one embodiment, time series data is organized into discrete events with normalized time stamps and the events are indexed by time and keyword. A search is received and relevant event information is retrieved based in whole or in part on the time indexing mechanism, keyword indexing mechanism, or statistical indices calculated at the time of the search.

Abstract: Distributed batch processing on an eventually consistent storage system is efficiently performed. A control node includes an execution control unit and a re-execution control unit. The execution control unit causes a processing node to execute predetermined processing that includes reading of data for a key stored in a distributed data store. The re-execution control unit determines, after causing the processing node to execute the predetermined processing, presence or absence of a possibility that inconsistency occurred on data for the key stored in the distributed data store at a time of execution of the predetermined processing, based on a representative value of the data. Then, the re-execution control unit causes, when it is determined that there is a possibility that the inconsistency occurred, the processing node to re-execute the predetermined processing at a time point when resolution of the inconsistency is verified.

Abstract: A data storage system for use with a multi-threaded processing system receives concurrent requests to store data to a common data store, and efficiently and securely swaps an active data store for a new data store while avoiding conflicts arising from multiple threads attempting to swap a same data store and minimizing reliance on operations that re-attempt actions upon failure of an attempted action, thereby improving performance of the data storage system and also the multi-threaded processing system.

Abstract: A database engine receives a human-readable database query that includes a subquery, and parses the database query to build an operator tree. The operator tree includes a subtree corresponding to the subquery. The database engine estimates the number of rows that will accessed when the subtree is executed and estimates the fraction of the cardinality of rows that will be filtered out by subsequent operations in the operator tree. In accordance with a determination that the estimated fraction exceeds a first threshold, the database engine inserts a domain constraint into the subtree that restricts rows retrieved by execution of the subtree, thereby forming a modified operator tree. The database engine executes the modified operator tree to form a final result set corresponding to the database query and returns the final result set.

Abstract: The present invention extends to methods, systems, and computer program products for forming data responsive to a query. Responding to a query can include selecting data views on top of data sources. A data catalog stores data elements from different data sources and stores links between data elements from the different data sources. A view can be selected for a query based on one or more of: classification of data included in the data catalog or prior usage of data included in the data catalog. A selected data view is populated with data elements from the data catalog using the links to determine that data elements spanning multiple data sources satisfy the query. The data catalog can be used to identify relationships between data elements from different data sources that would not otherwise be identified.

Abstract: Online search retrieval is improved by automatic generation of key phrases. When a search engine crawls an electronic document, key words and phrases greatly help organize the electronic document to one or more topics. A quotient matrix defines a ratio of a key phrase to a total number of words in the electronic document. A correlation coefficient may also determine which key phrase correlates to the electronic document. A title key phrase may then be generated in response to the correlation coefficient having a positive value. When the search engine crawls the electronic document, the title key phrase may be provided as metadata.
