Classification is the process of organizing items, concepts, or data into groups based on shared characteristics or rules. It is used in many fields, such as biology to arrange species, machine learning to assign labels to data, and library science to sort books. Effective classification makes information easier to search, compare, and analyze. It often relies on clear criteria and consistent standards so that different users or systems can understand and apply the same structure. In data science and artificial intelligence, classification models learn from examples to predict the correct category for new, unseen inputs.
