Abstract

It is well konwn that the real-world data tend to exist many data quality problems such as incompleteness and nosiy data. Data preprocessing technology can improve data quality effectively and provide more reliable data for the next step. A data preprocessing approach for daylight climate data is presented in this paper according to the characteristics of this data. Then this approach is applied to the real-world data and the experimental results show that the approach can enhance the data quality effectively. Besides, the integration of the domain knowledge into data preprocessing is emphasized in this paper in order to make data preprocessing more effective and more targeted.
