A Method of Computing Iceberg Cube Based on Non-antimonotonic Constraint
Information Science and Cloud Computing Companion（2013）
摘要
To compute iceberg cube based on non-antimonotonic constraint, we propose a modified Star-Cubing method by means of converting constraint by top-k. It uses a method of top-k to convert a constraint to an antimonotonic constraint and carries out the star-reduction in the base cuboid table, thus reduces the cost of the shared dimension pruning in Star-Cubing. Experimental results show that the method could compute iceberg cube based on non-antimonotonic constraint availably and improve the efficiency of computation method at the same time.
