    摘要: A database including vertical tables useful for storing large numbers of objects having potentially thousands of attributes in, e.g., e-commerce applications. To support querying the vertical database using conventional SQL, a horizontal view over the underlying vertical tables is defined, and then queries are posed against the view. The queries are automatically transformed and executed against the vertical tables. If desired, the query results can be transformed back to a horizontal format. In this way, it appears to the user that a conventional horizontal data format is being used.

    摘要: A system, method, and computer program product to automatically eliminate the distribution information available for reconstruction from a disguised dataset. The invention flattens input numerical values into a substantially uniformly distributed dataset, then maps the uniformly distributed dataset into equivalent data in a target distribution. The invention allows the incremental encryption of new values in an encrypted database while leaving existing encrypted values unchanged. The flattening comprises (1) partitioning, (2) mapping, and (3) saving auxiliary information about the data processing, which is encrypted and not updated. The partitioning is MDL based, and includes a growth phase for dividing a space into fine partitions and a prune phase for merging some partitions together.

    摘要: The present invention provides a method and system of partitioning authors on a given topic in a newsgroup into two opposite classes of the authors. In an exemplary embodiment, the method and system include identifying all links among the authors, where each link represents a response from one of the authors to another of the authors and analyzing the identified links, where the identified links are assumed to be more likely to be antagonistic links rather than non-antagonistic links. In an exemplary embodiment, the identifying includes assigning a vertex of a graph to each of the authors and assigning an edge of the graph to each interaction between two of the assigned vertices corresponding to two of the authors. In an exemplary embodiment, the analyzing includes solving a min-weight approximately balanced cut problem on a co-citation matrix of the graph, thereby generating the two opposite classes of the authors.
