英文摘要：

Librarians play a key role in the library information ecosystem. Librarians and library users interact and influence each other in process and use of information. Tagging defined by network users is used in description of words and phrases in different information resources. When it is used in library,user-oriented service will become the target of information service,and the role of information service persons,information organization methods and information low efficiency will change. However,rational planning of ecosystem,rational control of tagging,and improvement of librarian information literacy can reduce the negative effect of tagging.
