We demonstrate our approach on a real data set and show how it can substantially improve both the search for interesting patterns by the mining algorithm and the interpretation of the mining results by the analyst.

Mining Association Rules from XML Datae new challenges and opportunities that this topic sets to the data mining community. More specifically, we introduce an . for mining association rules. This extension is used throughout the paper to better define association rule mining within XML and to emphasize its implications in the XML context.

An Efficient ,-Medoids-Based Algorithm Using Previous Medoid Index, Triangular Inequality Eliminationstrate that the proposed algorithm applied to . may reduce the number of distance calculations by 67% to 92% while retaining the same average distance per object. In terms of the running time, the proposed algorithm may reduce computation time by 38% to 65% compared with the . algorithm.

An Algorithm for Building User-Role Profiles in a Trust Environment1sification phase). This algorithm will be incorporated in the Role Server architecture, currently under development, enhancing its ability to dynamically adjust the amount of trust of each user and update the corresponding role assignments.
