Welcome to VOSviewer

VOSviewer is a software tool for constructing and visualizing bibliometric networks. These networks may for instance include journals, researchers, or individual publications, and they can be constructed based on citation, bibliographic coupling, co-citation, or co-authorship relations. VOSviewer also offers text mining functionality that can be used to construct and visualize co-occurrence networks of important terms extracted from a body of scientific literature.

Problems with Scopus data

November 12, 2018. Many users of VOSviewer have reported problems in working with CSV files exported from Scopus. These problems are caused by bugs in the export functionality of Scopus. The Scopus team is working on fixing these bugs. In the meantime, we recommend to make use of other data sources, such as Web of Science, Dimensions, PubMed, or Crossref.


VOSviewer version 1.6.9

VOSviewer version 1.6.9 was released on August 29, 2018. This version offers support for data exported from Dimensions. Data from Dimensions can be used to create co-authorship, citation, and bibliographic coupling maps. More information is available here.
