VOSviewer version 1.4.0 released

[Nees Jan van Eck]

Dear colleagues,

A new version of the VOSviewer software for bibliometric mapping has been
released. The software can be freely downloaded at www.vosviewer.com. The
most important new feature is the use of text mining techniques for creating
maps based on large text corpora. Other new features include improved
functionality for creating new maps, extensions of the map file format, and
improved support for Pajek files. Also, various requests from the user
community have been incorporated in the new version of VOSviewer.

Some applications of the new text mining functionality of VOSviewer are
presented in a short paper available at http://arxiv.org/abs/1109.2058.

Feedback on this project is very much welcomed.

Best regards,

Nees Jan van Eck
