Measuring and modelling data quality for quality-awareness in data mining

Abstract

This chapter presents an overview of data quality management, data linkage and data cleaning techniques that can be advantageously employed for improving the quality awareness of the knowledge discovery process. Based on this database-oriented overview of data quality management, this chapter also presents a pragmatic step-by-step framework for data quality awareness and enhancement before warehousing and during the knowledge discovery process. Each step may use, combine and exploit the data quality characterization, measurement and management methods, and the related techniques proposed in the literature. © Springer-Verlag Berlin Heidelberg 2007.
