An Enhancement of Hierarchical Clustering Algorithms

Nowadays, with large and great expansion of the Internet, worldtechnology, and users of system, we need systems that help us to organize, analyze, and arrange the data in a way that helps us to use them better. The data mining system is one of these systems. The concept of data mining (sometimes called knowledge discovery) refers to extracting (mining) important information from large amount of data [1]. In other words, we can say that the data mining systems involve a lot of technology and many algorithms that help us to extract great variety of information that are either stored in large database or other information repositories. It allows users to categorize data from many dimensions.
