Welcome to the VOSviewer web site
VOSviewer is a freely available computer program that can be used for the following purposes:
- VOSviewer can be used to construct maps based on network data. Maps are constructed using the VOS mapping technique and the VOS clustering technique.
- VOSviewer can be used to view and explore maps. It can show a map in various different ways, each emphasizing a different aspect of the map. It offers functionality such as zooming, panning, and searching, which facilitates the detailed examination of a map.
VOSviewer is primarily intended to be used for bibliometric analyses. The program can for instance be used to construct maps of publications, authors, or journals based on co-citation data or to construct maps of keywords based on co-occurrence data. Various examples of maps constructed using VOSviewer are available here.
VOSviewer has been written in the Java programming language and runs on most hardware and operating system platforms. VOSviewer can be downloaded here. The program can also be started directly by clicking the Launch button below.
