Abstract:The computerization of our society has substantially enhanced our capabilities for both generating and collecting data from diverse sources. A tremendous amount of data has flooded almost every aspect of our lives. There is a need in transforming the vast amount of data into useful information and knowledge. This has led to the generation of promising and flourishing frontier in computer science called data mining. Data mining is the automated or convenient extraction of patterns representing knowledge implicitly stored or captured in large databases, data warehouses, the web, other massive information repositories or data streams.
