Knowledge can be defined as a justified true belief. It is a valuable asset that can be used to make better decisions, improve products and services, and understand the world around us.<\/p>\n<p>Data is the raw material that KDD uses to extract knowledge. Data can be structured or unstructured. Structured data is data that is organized in a defined format, such as a table or a spreadsheet. Unstructured data is data that is not organized in a defined format, such as text, images, or videos.<\/p>\n<p>Data mining is a process that uses statistical, mathematical, and machine learning techniques to extract patterns from data. Data mining can be used to find patterns in data that are not obvious to humans.<\/p>\n<p>KDD is a multi-step process that includes the following steps:<\/p>\n<ol>\n<li><strong>Data selection<\/strong>. This step involves selecting the data that will be used in the KDD process.<\/li>\n<li><strong>Data preprocessing<\/strong>. This step involves cleaning and transforming the data so that it is ready for mining.<\/li>\n<li><strong>Data mining<\/strong>. This step involves using data mining techniques to extract patterns from the data.<\/li>\n<li><strong>Knowledge representation<\/strong>. This step involves representing the knowledge that has been extracted from the data in a way that is understandable by humans.<\/li>\n<li><strong>Knowledge evaluation<\/strong>. This step involves evaluating the knowledge that has been extracted from the data to determine its accuracy and usefulness.<\/li>\n<li><strong>Knowledge deployment<\/strong>. This step involves deploying the knowledge that has been extracted from the data to solve a problem or improve a process.<\/li>\n<\/ol>\n<p>KDD is a powerful tool that can be used to extract knowledge from data. However, it is important to note that KDD is not a magic bullet. It is a complex process that requires careful planning and execution.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;data&#8221; option2=&#8221;knowledge&#8221; option3=&#8221;rules&#8221;
