摘要： A system for a data stream management system includes a filter transport aggregate for a high speed input data stream with a plurality of packets each packet comprising attributes. The system includes an evaluation system to evaluate the high speed input data stream and partitions the packets into groups the attributes and a table, wherein the table stores the attributes of each packets using a hash function. A phantom query is used to define partitioned groups of packets using attributes other than those used to group the packets for solving user queries without performing the user queries on the high speed input data stream.

摘要： A method and system are described to multicast with an adaptive dual state. The system receives multicast traffic over a membership tree including a first plurality of nodes connected in a first topology destined for a plurality of multicast members of a first multicast group. Next, the system determines a rate of multicast traffic that exceeds a predetermined threshold based on the receiving the multicast traffic. Next, the system generates a dissemination tree including a second plurality of nodes connected in a second topology to reduce a number of hops to communicate the multicast traffic to the plurality of multicast members of the first multicast group. Finally, the system forwards the multicast traffic to the plurality of multicast members of the first multicast group over the dissemination tree.

摘要： The present disclosure is directed to systems, methods, and computer-readable storage media for anonymizing data over multiple temporal releases. Data is received, and nodes and connections in the data are identified. The data also is analyzed to identify predicted connections. The nodes, the connections, and the predicted connections are analyzed to determine how to group the nodes in the data. The data is published, and the grouping of the nodes is extended to subsequent temporal releases of the data, the nodes of which are grouped in accordance with the grouping used with the data.

摘要： A method and system for performing a data stream query. A data stream query requiring a join operation on multiple data streams is approximated without performing the join operation. It is determined whether conditions of the query are proper to accurately approximate the join operation, and if the conditions are proper the join operation is approximated. The join operation is approximated by independently aggregating values of the data streams and comparing the independently aggregated values.

摘要： In embodiments of the disclosed technology, indexes, such as inverted indexes, are updated only as necessary to guarantee answer precision within predefined thresholds which are determined with little cost in comparison to the updates of the indexes themselves. With the present technology, a batch of daily updates can be processed in a matter of minutes, rather than a few hours for rebuilding an index, and a query may be answered with assurances that the results are accurate or within a threshold of accuracy.
摘要翻译： 在所公开的技术的实施例中，诸如反向索引之类的索引仅在必要时被更新以保证在与索引本身的更新相比较较少成本的预定阈值内的应答精度。 使用本技术，可以在几分钟内处理一批每日更新，而不是几个小时来重建索引，并且可以回答保证结果准确或准确的阈值。

摘要： A method and system for truth discovery may implement a methodology that accounts for accuracy of sources and dependency between sources. The methodology may be based on Bayesian probability calculus for determining which data object values published by sources are likely to be true. The method may be recursive with respect to dependency, accuracy, and actual truth discovery for a plurality of sources.
