Manual classification is the process of organizing items or data into categories based on specific criteria. This method relies on human judgment to evaluate and sort information, such as documents, images, or products. It is often used in fields like library science, data management, and archiving to ensure that information is easily accessible and retrievable. In manual classification, individuals examine each item and assign it to a predefined category. This can involve labeling, tagging, or filing items according to their characteristics. While effective, manual classification can be time-consuming and may introduce human error, making it less efficient than automated methods in large-scale applications.
