The method hierarchically clusters dimension instances by also taking fact-table measures into account. Thus, we enhance the clustering effect with respect to the possible analysis.  ...  Abstract In traditional OLAP systems, roll-up and drill-down operations over data cubes exploit fixed hierarchies defined on discrete attributes, which play the roles of dimensions, and operate along them  ...  This work is in partial fulfillment of the requirements of the Italian project VINCENTE PON02_00563_3470993 "A Virtual collective INtelligenCe ENvironment to develop sustainable Technology Entrepreneurship  ...
