Data Preprocessing in Data Mining

Data Mining (DM) is a new hot research point in database area. Because the real-world data is not ideal.it is necessary to do some data preprocessing to meet the requirement of DM algorithms. In this paper,we discuss the procedure of data preprocessing and present the work of data preprocessing in details. We also discuss the methods and technologies used in data preprocessing.
