Please provide examples of the classification methods used in the network resource catalogs.

(I) Types of network catalog resources

1, traditional classification type network resource catalog

Traditional classification is mostly based on disciplinary classification, and the network resource catalog that directly adopts traditional classification provides the function of browsing according to disciplines, which is more adaptable to the users who have the need for academic information to search for information. Traditional classification type network resources catalog basically follows the traditional classification of the major categories, but individual also slightly adjusted and trade-offs, some of which is to choose a part of the classification of the categories; some are removed from the individual categories and so on. In terms of the arrangement of classes, some of them are arranged in accordance with the linear arrangement of the classification, but some of them have been adjusted to incorporate the multidimensional expansion of the pluralistic division.

At present, all for the use of network information resources of the portal, this type of network resource catalog does not occupy the mainstream.

2, innovative network resources catalog

Innovative network resources catalog refers to the characteristics of network information resources, combined with the new environment of the network, new requirements to create a new type of network resources catalog. It is also called network information taxonomy. It serves as the mainstream catalog of network search tools, and is a shortcut for us to utilize network information resources. Thus, the principle of practicality, the principle of naturalness and the principle of relevance are the basic principles of preparing the network resource catalog.

(1) Principle of Practicality

The categories of network resources are mainly set according to the actual situation of the collected online resources and the query habits of online users, and the category setting should not only be comprehensive, but more importantly, useful. It is a user-oriented, network information resources for the classification system, has a strong practicality.

(2) the principle of naturalness

It adopts as little as possible of the overly academic, difficult to understand terminology, and as much as possible of the general, standardized, connotation and extension of the natural language is clear.

(3) the principle of relevance

It is mainly reflected in the search tool according to its own characteristics and the user groups to set up categories, it is not possible to set up categories according to the same standards, and according to the same standards to divide the following sub-categories. Sometimes the classification system in order to facilitate the user to find, specifically the use of very high frequency of things and categories listed separately, targeted class division, and in order to fully reflect the category, the use of targeted criteria
