Introduction
The process of identifying patterns, trends, variations, and correlations in big data is known as data mining. Data mining is one stage of KDD, a more complex process. It is a multi-step process that is iterative and includes various stages.
Although data mining and KDD are crucial elements in data analysis and knowledge extraction, they have different functions and objectives. In this article, we will explore the concepts of data mining and KDD, understand their tasks, and highlight their differences.
What is KDD?
KDD stands for knowledge discovery in databases. The KDD method is a complex and iterative approach to knowledge extraction from big data. Extraction of knowledge from massive data is accomplished through the intricate and iterative KDD process.
It is an extensive method that includes data mining as one of its steps. It includes utilising a variety of algorithms and statistical methods to sort through large amounts of data and identify relevant and valuable data. The following steps make up the cyclical process of KDD:
-
Data cleaning
-
Data Integration
-
Data selection
-
Data transformation
-
Data mining
-
Pattern evaluation
- Knowledge presentation
Applications of KDD
Some of the crucial applications of KDD are as follows:
-
Business and Marketing: User analysis, market prediction, Segmenting clients, and focused marketing are all examples of business and marketing databases.
-
Manufacturing: Predictive system analysis, process improvement, and quality control.
-
Finance: Fraud investigation, evaluation of credit risk, and stock market research in the finance sector can be analysed using the KDD method.
-
Healthcare: Drug progress, patient monitoring, and disease diagnosis from a large set of patient data.
- Scientific research: Identifying patterns in massive scientific databases, such as genetics, astronomy, and climate.
