VOSviewer book chapter

VOSviewer is discussed in detail in a recent book chapter. The chapter provides a tutorial in which the use of VOSviewer is demonstrated in a step-by-step manner. The chapter is based on VOSviewer version 1.5.5. Some of the improvements and extensions introduced in the most recent versions of VOSviewer are therefore not covered in the chapter. In addition to VOSviewer, the chapter also discusses the CitNetExplorer tool for visualizing and analyzing citation networks of publications.

VOSviewer paper

VOSviewer was originally introduced in a paper published in Scientometrics in 2010. In the meantime, VOSviewer has been improved and extended in many ways, so the paper is not fully up-to-date anymore. However, it still provides a useful introduction into the main ideas underlying VOSviewer.

AIDA booklet

The AIDA booklet introduces diverse case studies on research positioning and trend identification. These case studies are relevant for PhD candidates, researchers, group leaders, and policy makers. Many of the case studies make use of VOSviewer.

Thanks so much for all your work on VOSviewer. I'm working with an .ris file to construct a co-authorship network of 925 citations, I’m interested in visualizing a network of not only authors (.ris tag AU) but also editors (.ris tag A2). Is this possible?

Hello Team,
I'd like to congratulate you on such a tremendous project, I think you guys are doing great work putting this amazing software out there. I'd like to navigate this further but I've encountered a bit of a challenge using your product. After downloading it I tried to launch the app but keep getting the error message "Unable to load Java runtime environment. I downloaded the MacOS version because my laptop is a Macbook Pro 2. Please can you help me to rectify this issue?

Dear VOSviewer Support Team,
I hope this email finds you well.
I am currently using VOSviewer on my MacBook for analyzing data, but I am encountering an issue with reading CSV files. Specifically, when I upload a Scopus CSV file into VOSviewer, I consistently receive a warning message that says "incorrect use of quotes."
I would greatly appreciate your assistance in resolving this issue. Could you please provide guidance or suggestions on how to address the problem with CSV file formatting?
Thank you very much for your support.
Best regards,
Budiawan

Hi, I'm helping a researcher with Vosviewer. She wants to get a list in csv of the references with title, author, journal, year etc. of the clusters she has produced. We try, but only succeed in getting out what is visible in the cluster, eg authors, in a text file. Is there a way to get a list of all information about the references in a cluster?
Thanks in advance!

Given this, what does "clustering" mean? What is the criteria used to assign an item (an author) to a cluster?

Have the developers noticed that the red/green/blue columns in map files are being ignored in versions 1.6._19 and 1.6.20? I have tried to submit a message about this bug via the contact form twice but I am not confident it is submitting successfully, it just loads a blank page. Does anyone have a macOS installer for version 1.6_16 they might be able to share? That's the last version where this feature was still working, but I've unfortunately uninstalled it from my computer.

Dear all, is it possible to save our results with VOSviewer and open them later in the program?
When I save the file with "save...." after opening it in VOSviewer, it is not possible to see the lines connecting the keywords. I can only see certain keywords

  Magdelena, what format are you saving to? I believe if you save your work to the map and network files, reopening these should reproduce the graphs exactly as they were when you saved them.
