Why Is Data Preprocessing Important? вЂў No quality data, no quality mining results! вЂў Quality decisions must be based on quality data вЂў e.g., duplicate or missing data may cause incorrect or even misleading basic descriptive statistics. вЂў Data warehouse needs consistent integration of quality data! Normalization is a good technique to use when you do not know the distribution of your data or when you know the distribution is not Gaussian (a bell curve). You can normalize all of the attributes in your dataset with Weka by choosing the Normalize filter and applying it to your dataset.

вЂў Clustering is a process of partitioning a set of data (or objects) into a set of meaningful sub-classes, called clusters. вЂў Help users understand the natural grouping or structure in a data set. вЂў Clustering: unsupervised classification: no predefined classes. вЂў Used either as вЂ¦ Term normalization is the process of mapping variants of a term to a single, standardized form and constitutes an important part of the process of automatic term recognition.As an example of term variation, consider the terms IL2, IL-2, and interleukin-2, which all represent the same biological concept.Term variation can present a major obstacle to the effective use of dictionaries by text

Preserving Data Stream Mining in recent years have become one of the important issues in the field of data mining. Several privacy preserving algorithms have been proposed and are used nowadays. In this paper, we propose a new method using min-max normalization for preserving data through data mining. Term normalization is the process of mapping variants of a term to a single, standardized form and constitutes an important part of the process of automatic term recognition.As an example of term variation, consider the terms IL2, IL-2, and interleukin-2, which all represent the same biological concept.Term variation can present a major obstacle to the effective use of dictionaries by text
