Cube index for unstructured text analysis and mining

A Cube Index Model on multidimensional text database and effective study of Online Analytical Processing (OLAP) over such data had been experimented and found to provide good results. We had proposed a cube index model for unstructured text database derived from the text index structures. There are three kinds of hierarchies on it. They are term hierarchy and dimensional hierarchy. This paper proposes the document hierarchy. Two new operations scroll up and scroll down are discussed exclusively for the cube index. The implementation, OLAP execution and query processing on the index are studied. The performance study gives a good guarantee of the model to be used on unstructured text database.
