The Chinese databases used in the field of novelty search of Chinese scientific papers are as follows:

2. Wanfang Data is a comprehensive academic resource platform covering various fields such as science and technology, humanities, and social sciences. The database provides a large number of Chinese journals, doctoral and master's theses, conference papers and other resources, and also includes some foreign literature.
3. VIP.com is a database mainly focused on scientific and technological literature retrieval, covering engineering, medicine, biology and other fields. The database provides a large number of Chinese journals, doctoral and master's theses, patents and other resources, as well as some foreign literature.
Wanfang Data Resource System (China Info) was developed by China Institute of Science and Technology Information and Wanfang Data Co., Ltd. The database includes journals in a wide range of disciplines, including academic and non-academic journals, and provides full-text search of about 2,000 electronic journals.
The included academic journals have all obtained the inclusion certificate of "China Core Journals (Selection) Database Source Journals". Some journals even changed "selection" to "selected" or removed it altogether. Many authors therefore mistakenly believe that this is a core journal.
The content of the literature database:
corresponds to its traditional literature information. The content and formal characteristics of a book or document form an item after being described. An entry is the basic unit of documentary information.
In the literature database, an item is called a record, and the record is also the basic unit that constitutes the literature database. An entry consists of bibliographic items such as article title, author, and subject. The bibliographic items are called fields in the literature database.
A field can be subdivided into several sub-fields. In this way, the literature database is composed of a series of continuous records, fields and sub-fields, and forms a hierarchical tree structure.
