    摘要: The present invention provides a method for updating betweenness centrality of a graph, which obtains the betweenness centrality of an unweighted graph, which is updated when edges are updated. First of all, the method is performed by obtaining a minimum union cycle (an MUC) of the updated graph, and extracting an MUC (MUCU) containing a vertex, which is incident to the updated edge. And a first betweenness centrality due to the shortest paths in the MUCU, and a second betweenness centrality due to the shortest paths, not included in the MUCU, are calculated. And finally, a final betweenness centrality of the graph is obtained by adding the first and second betweenness centralities. By using the method, the search space and calculation cost can be remarkably reduced.

    摘要: Vectors representing objects in n-dimensional space are approximated by local polar coordinates on partitioned cells of the data space in response to a query, e.g., a query data vector entered with a request to find “k” nearest neighbors to the query vector. A set of candidate near neighbors is generated using the approximations, with the local polar coordinates being independent of the dimensionality of the data space. Then, an answer set of near neighbors is returned in response to the query. Thus, the present invention acts as a filter to reduce the number of actual data vectors in the data set that must be considered in responding to the query.

    摘要: A method of processing a query about an Extensible Markup Language (XML) data. The XML query processing method includes the first step of representing the XML data in the form of an XML graph, the second step of creating and updating an Adaptive Path indEX (APEX) based on frequently used paths extracted from previously processed XML queries and the XML graph, and the third step of processing an XML query using the APEX. The XML query processing is capable of improving the performance of processing the query by extracting frequently used paths from path expressions having been used as queries for XML data and updating the APEX through the use of the frequently used paths.
