A New Data Cube for Integrating Data Mining and OLAP

Recently there is much need of discovering useful knowledge from massive log-data which are generated by Web-based information systems. Such log-data have multiple attributes about when and where what events occurred. In order to find useful knowledge from this data-set. many aggregate queries and data-mining queries must be issued under various constraints in the "when/where/what" -space. To support this process. this paper proposes a new data cube named llemset Cube. This cube directly supports data-mining task in a multi-dimensional space of analysis. Definition and algorithms of the itemset cube and its application to a real data-set are described.
