Data mining combining data walkthrough

Data mining is a method to discover unknown and useful knowledge from large amount of data, and various discovering methods have been proposed including methods using machine-learning algorithms. In this study, a new method is proposed in which data mining procedure is accomplished by the walkthrough of a business expert in the artificial space of preprocessed data. The features of this new method are the coupling of visualization and analytical procedure in data mining process, using the knowledge of the business expert as the heuristics of the data mining algorithm, and using artificial 3-dimensional immersive data space in which the business expert can exist, investigate, and manipulate data. The artificial immersive data space is generated by the techniques in virtual reality.
