The integrated data mining tool MineKit and a case study of its application on video shop data

The second goal of this paper is to report the result of evaluating MineKit in a real-world data set. This case study is relevant for data mining mainly for two reasons. First, the original data set, li ke a typical realworld data set, was not previously prepared for data mining activities, so that we had to spent a significant time preparing the data. Hence, we have actuall y gone through the most time-consuming phase of the knowledge discovery process. This issue is usually ignored in the data mining literature, which focus on the data mining phase only.
