Since Jim Gray introduced the concept of "Data cube" in 1997, data cube, associated with OnLine Analytical Processing (OLAP), has become a driving engine in data warehouse industry. Because the boom of Internet has given rise to an ever increasing amount of text data associated with other multidimensional information, it is natural to propose a data cube model that integrates the power of traditional OLAP and IR techniques for text. In this paper, the authors propose a Text-Cube model on multidimensional text database and study effective OLAP over such data.
