Research on Interest-driven Iceberg Cube Construction and Incremental Update Method
用户兴趣驱动的冰山数据立方体构建及更新方法研究

This paper proposed a matrix-based iceberg construction method called MICC, in order to reduce the space Consumption during the full materialization for a data cube. Users' interests arc considered as the standard to construct an iceberg cube. On the basis of the result of MICC, the paper proposed an incremental update method to dynamically update the iceberg cube while the users' interests are changing. An experiment proves the efficiency and accuracy of these two methods MICC and ICIU.
