Close classification is a type of classification system in which items are organized into a large number of specific or detailed categories. This approach is often used when the items being classified have many distinct characteristics or attributes that can be used to distinguish between different categories.
In a close classification system, the categories are typically defined by a set of specific or detailed characteristics, and the items are assigned to the categories based on which characteristics they possess. For example, in a close classification of animals, the categories might include mammals, birds, reptiles, and fish, and the animals might be further classified into subcategories based on specific characteristics such as their size, shape, or habitat.
One of the main advantages of close classification is that it allows for a high level of detail and precision. Because the categories are specific and detailed, it is possible to assign items to very specific categories, making it easier to locate and access specific items.
However, one of the main limitations of close classification is that it can be complex and may require a lot of effort to create and maintain. It can also be difficult to change or modify a close classification system once it is established.
Overall, close classification is a useful tool for organizing and categorizing items in a logical and structured way, but it may not be the most suitable approach in situations where the items being classified are very diverse or where the classification system needs to be highly flexible.
