Extended data:

The advantages of line classification are large amount of information, clear hierarchy and strong logic, which conforms to the habit of traditional application and is suitable for both manual operation and computer processing. However, the classification table has a certain solidification, which is inconvenient to change at any time as needed, and is not suitable for multi-angle information retrieval.

The main advantage of face classification is that it has great flexibility in classification structure, that is, the change of category in any face in the classification system will not affect other faces, and faces can be added or deleted. Furthermore, the classification structure of "face" can be searched according to any combination of "face", which is beneficial to computer information processing.
