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 co-citation, bibliographic coupling, 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.

VOSviewer version 1.6.2

VOSviewer version 1.6.2 was released on August 27, 2015. This version includes the following new features:

  • Improved network visualization. Support for curved and colored lines of variable thickness has been added.
  • Multi-dimensional visual analysis. Items in a network can have multiple weight and score attributes. This for instance makes it possible to easily produce a series of overlay visualizations, which facilitates multi-dimensional visual analysis of network data.
  • Improved Web of Science, Scopus, and PubMed support. Various improvements have been made. Term maps created based on Web of Science, Scopus, or PubMed data for instance automatically include overlay visualizations showing the age and citedness of publications.
