Key Differences
Classification and categorization are both methods of organizing complex sets of information or objects. Classification is a more formal, often scientific, method of sorting based on established criteria. For instance, biological classification sorts organisms by genus and species. Categorization, by contrast, is a more general practice, sometimes intuitive or cultural, which groups items by shared characteristics or utility, like categorizing books by genre.
While classification follows a hierarchical structure, categorization does not necessarily. In classification, a digital camera is designated as a Canon EOS 5D based on specific features that fit into a pre-defined structure of camera types. Categorization, however, would place the same camera under a broad category like 'electronics' or 'photography gear' based on its general use.
In educational settings, classification helps in creating a structured learning environment where knowledge is categorized into subjects and further classified into topics. Categorization may be used to group different learning styles or teaching methods, without a strict hierarchy, to address the diversity of student needs.
Classification often requires more detailed analysis and the use of specific criteria. For example, in a library, books are classified according to a precise system like the Dewey Decimal System. In contrast, categorization might simply group books into fiction and non-fiction without further subdivisions.
In the context of data management, classification is crucial for organizing information in a way that allows for efficient retrieval, often using complex algorithms. Categorization, on the other hand, could be employed to tag data for broader search functionality, such as grouping content by themes or subjects on a website.

Categorization
Categorization is the human ability and activity of recognizing shared features or similarities between the elements of the experience of the world (such as objects, events, or ideas), organizing and classifying experience by associating them to a more abstract group (that is, a category, class, or type), on the basis of their traits, features, similarities or other criteria. Categorization is considered one of the most fundamental cognitive abilities, and as such it is studied particularly by psychology and cognitive linguistics.
