摘要： A method and apparatus for providing an anonymization of data are disclosed. For example, the method receives a request for anonymizing, wherein the request comprises a bipartite graph for a plurality of associations or a table that encodes the plurality of associations for the bipartite graph. The method places each node in the bipartite graph in a safe group and provides an anonymized graph that encodes the plurality of associations of the bipartite graph, if a safe group for all nodes of the bipartite graph is found.

摘要： A system and method for choosing data sources for use in a data repository first chooses an initial selection of data sources based on keywords. An exploration tool is provided to organize the sources according to content and other attributes. The tool is used to pre-select data sources. The sources to include in the data repository are then selected based on a marginalism economic theory that considers both costs and quality of data.

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 distributed transformation network provides delivery of content from a content publisher to a content recipient. Content from the content publisher is received at an entry node of the distributed transformation network and transmitted to a transformation node in the distributed transformation network. The content is transformed according to publisher, recipient or network administrator specifications and transmitting to delivery nodes which deliver the transformed content to the content recipient. The published content may be in an XML-based format and transformed into an XML-related format or any other structured language format as desired in the provided specification.

摘要： A method for mapping relationships in a database results in a cluster graph. A representative sample of records in each of a plurality of tables in the database is analyzed for nearest neighbor join edges instantiated by the record. Records with corresponding nearest neighbor join edges are grouped into clusters. Cluster pairs which share a join relationship between two tables are identified. A weighting may be applied to cluster pairs based on the number of records for the cluster pair. Meaningful cluster pairs above a weighted threshold may be ordered according to table and displayed as a cluster graph. Analyses of the cluster graph may reveal important characteristics of the database.

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.
