 Summary:

Wikipedia's classification system is a complex but critical organizational tool designed to help users and editors access and manage information more efficiently. By following classification guidelines, you can ensure that the classification system is organized and useful.

This document details the purpose, principles, types, hierarchies, standards, and maintenance of classifications, providing a clear framework to ensure that classifications are effective and accurate. Community collaboration and discussion are also emphasized as key steps in implementing and managing the classification to ensure continuous improvement and adaptability of the classification system.

1. Purpose of classification

The main purpose of categorization is to organize and group entries, making it easier for users to find relevant content. This not only helps readers, but also makes it easier for editors to quickly find relevant entries when maintaining and expanding Wikipedia content.

2. Classification principles

The classification system should be simple, meaningful and well-structured. The names of the categories should be clear and descriptive, so that users can understand exactly what the categories are about.

3. Types of categories

Topic categories: These are the most common types of categories and are based on the topic of the entry.

Set categories: These are used for collections of similar types of entries, such as “people born in a certain year”.

List categories: These categories contain entries in the form of lists.

4. Classification and redirection

Sometimes an entry may fit into more than one category. You can use “redirection categories” to help users find entries in different category paths.

5. Criteria for categorization

Entries should only be categorized if they meet the categorization criteria. Over-categorization (i.e. assigning too many categories to an entry) and under-categorization (i.e. not assigning enough categories to an entry) should be avoided.

6. Management and maintenance

Regular checking and maintenance of the classification system is necessary to ensure its accuracy and usefulness. In particular, attention should be paid to isolated entries in the classification (i.e., entries that do not belong to any subcategory) and scattered entries (i.e., entries that are improperly categorized).

Interesting Points:

The design of the hierarchical structure

Wikipedia's classification system employs a hierarchical structure that progressively refines from broad categories to specific subcategories. The design is similar to a tree diagram, where each top-level category (e.g., “Art”) has multiple subcategories (e.g., “Paintings”, “Music”), which are further subdivided into specific categories (e.g., “Impressionist Paintings”). “Impressionist paintings”). This hierarchical structure allows users to search for information layer by layer, thus improving search efficiency and logical organization of information.

Question: In Wikipedia's categorization system, why is there a need to strictly avoid over-categorization and under-categorization, and how do these two affect information finding and user experience respectively?
