This step consists of removing outliers, dealing with noiseand missing values in the data, and accounting for time sequence information and knownchanges. This step generates patterns in a particular representational form, such as classificationrules, decision trees, regression models, trends, etc. The ongoing rapid growth of online data due to the Internet and the widespread use of databases have created an immense need for KDD methodologies. It concentrates on data preparation, clustering and association rule learning (required for processing unsupervised data), decision trees, rule induction algorithms, neural networks, and many other data mining methods, focusing predominantly on those which have proven successful in data mining projects. 20, 2019, Adepeju Abimbola Opaleye, Advances in data collection, widespread use of bar codes for most commercial products, and the computerization of many business and government transactions have flooded us with data and generated an urgent need for new techniques and tools that can intelligently and automatically assist in transforming this data into useful knowledge. Mostly, visualization techniques are being used to make users understand and interpret information. Depending on the requirements, this step can be as simple as generatinga report or as complex as implementing a repeatable KDP. Specific aims include identification of data quality problems, initial insights into the data, and detection of interesting data subsets. of 6th International Semantic Web Conference (ISWC 2007), 2nd Asian Semantic Web Conference (ASWC 2007), LNCS 4825, pages 225238, Busan, Korea, 1115 November 2007. http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.

We restrict our discussion to those models that have been popularized in the literature and have been used in real knowledgediscovery projects. The final step consists of incorporating the discoveredknowledge into the performance system, and documenting and reporting it to the interestedparties.

While the acknowledge that extracting knowledge from data can be accomplished through a variety of methods some not even requiring the use of a computer. Knowledge Presentation − In this step, knowledge is represented. This knowledge discovery approach is what distinguishes Data Mining from other texts in this area. Thus, you should select a data set or subset of data, in other words data samples, on which you need to perform data analysis and get useful knowledge. Abstract- Data mining (the analysis step of the "Knowledge Discovery in Databases" process, or KDD) an interdisciplinary subfield of computer science, is the computational process of discovering patterns in large data sets involving methods at the intersection of artificial intelligence, machine learning, statistics, and database systems. Appropriate method(s) is to be selected for looking for patterns from the data. The authors of this model declare that a number of loops betweenany two steps are usually executed, but they give no specific details. We should have enough quantity of data to perform data mining. Data Mining and Knowledge Discovery Handbook, Second Edition is designed for research scientists, libraries and advanced-level students in computer science and engineering as a reference.

The efforts to establish a KDP model were initiated in academia. So, we need a system that will be capable of extracting essence of information available and that can automatically generate report, The two process modelsdeveloped in 1996 and 1998 are the nine-step model by Fayyad et al. The overall goal of the data mining process is to extract information from a data set and transform it into an understandable structure for further use. Authors: Usama M. Fayyad.

The following diagram shows the process of knowledge discovery −. Although the models usually emphasize independence from specific applications and tools, theycan be broadly divided into those that take into account industrial issues and those that do not.However, the academic models, which usually are not concerned with industrial issues, can bemade applicable relatively easily in the industrial setting and vice versa. Major Applications: The nine-step model has been incorporated into a commercialknowledge discovery system called MineSet(for details, see Purple Insight Ltd)The model has been used in a number of different domains,including engineering, medicine, production, e- business, and software development.
