I3: Intelligent, Interactive Inspection of Cubes.




Source code

The goal of the  project i(eye-cube) is to extend multidimensional OLAP data cubes with ad hoc interactive mining primitives.

Multidimensional OLAP products provide an excellent opportunity for integrating mining functionality because of their widespread acceptance as a decision support tool and their existing heavy reliance on manual, user-driven analysis. Most OLAP products are rather simplistic and rely heavily on the user's intuition to manually drive the discovery process. Mining technology can play a fitting role in improving the state of these products.  We propose a suite of extensions in the form of a toolkit attached with a OLAP product that will enable richer, faster answering of queries that are currently handled through manual exploration. 

The following is a list of available operators in the iCube project.

iDiff: Compact summary of reasons for differences in top-level aggregates
iExplore: Watch user browse the data and use that to define information content of unseen cells.
iRelax: Generalize from specific cases to general cases.
