Literature introduction is an essential step in literature review or paper writing. However, many people will find a problem when importing documents, that is, the imported documents are always repeated. There are many reasons for this problem. Let's analyze them one by one.

On the Setting of Document Management Software

Document management software is the main tool for importing documents, and the setting of document management software will directly affect the results of importing documents. If the document management software is not set correctly, it will lead to duplicate documents. For example, some software automatically removes duplicate content when importing documents by default. If you don't turn on this setting, it will be duplicated.

Document database problem

Literature database is the source of imported literature, and if there is something wrong with the literature database itself, it will also lead to duplication when importing literature. For example, in some databases, there may be multiple versions of the same document, which will lead to duplication if we don't pay attention to filtering.

Incomplete or inaccurate document information

When importing documents, if the document information is incomplete or inaccurate, it will also lead to document duplication. For example, the author's name of some documents may be spelled in many different ways. If you don't pay attention to unification, the same document will be treated as a different document and imported repeatedly.

Duplication is a common problem when importing documents, but as long as you pay attention to the above points, you can effectively avoid this situation.
