What are the similarities and differences between traditional book classification and network classification?

Classification objects are different: traditional classification takes physical and substantive documents such as paper documents, tapes and CDs as the main processing objects, and indexes and sorts out the contents of the documents. Network classification takes the information resources on millions of servers as the processing object, and organizes and filters them. Information is digital, multimedia, dynamic and virtual.

The knowledge range of information is different: the traditional classification takes the document collection department as the object of use, the publication of documents is controlled, the content is screened to a certain extent, and the classification system is stable. Network classification takes search engines or large websites as the object of use, and the network information is generally uncontrollable, including almost all fields of human knowledge, which requires it to be highly flexible and adapt to the dynamic nature of network information.

The function of classification is different: traditional classification indexes all documents, compiles classification retrieval tools and organizes classification shelving, and classification indexes are basically manual. Network classification establishes a classified navigation system of network information by indexing network information, and provides browsing and retrieval means. The establishment and maintenance of classified navigation system is mainly manual or man-machine combination.

The difference of classification marks is an indispensable part of traditional classification. Network classification organizes virtual information, and a category is a node of related information, which does not involve physical arrangement. Users don't need to ask for information according to classification tags, and they don't need to use classification tags, but as a background operation of network classification, classification tags are useful.

Different compilation methods:

1, knowledge framework. The former takes the subject attribute of literature content as the main clustering standard, takes the subject classification and specialty setting of colleges and universities as the basis, and takes into account the characteristics of literature to form a classification outline. The latter takes the theme as the main standard, centralizes the relevant information, and forms an outline that meets the query habits of various users.

2. The former system is unique. The latter can have more than two classification systems, both master classification system and slave classification system, to meet different query requirements.

3. Category classification: the former is a linear system. The latter division is not strictly according to grades, such as skip division; The multi-attribute relationship and correlation relationship of topics adopt cross-column classification, hypertext connection and multi-window display, and network system.

4. Category arrangement: The former emphasizes the content connection and logical relationship between categories, which is scientific and regular. In order to arrange a large number of appositive categories conveniently, quickly and automatically, the latter also widely uses word order and importance arrangement.

5. Description and comment: The former takes it as an important reference of indexer. The latter has no reference comments, and selectively lists the lower classes for easy linking.

6. Class name: the former strives to be scientific, accurate, standardized and stable. The latter pays more attention to users, and strives to be easy to understand, up-to-date, concise, and the accuracy is not as good as the former. User-oriented and background-oriented class names may be inconsistent.

7. Maintenance: The former is carefully modified. The latter can be modified at any time, but it is more complicated and heavier. ?

The reason why the information classification system is different from the traditional classification: The fundamental reason why the network information classification is different from the traditional classification is that the information resources under the network environment have different characteristics compared with the traditional literature. In this technical environment, the needs of users have also changed significantly.
