- Dr. Nees Jan van Eck gives an introduction 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.
More information can be found at: www.vosviewer.com
The best program that could ever exist for making research in a systematic way. Thank you very much.
it would be great to have a follow up on the various analysis that VOS can do :) thank you
This was very informative, clear and easy to understand. Thank you.
Can you do a longer tutorial on it to explain things into more details? A one hour video should suffice.
this app is a significant contribution to the science.
Good morning, I am fascinated with this software but, recently, I need to cross data from two databases (Web of Science and PsycInfo) these databases have different ways of exporting data and therefore are read in different ways. What can I do about it?
You have made an immense contribution to the field of research.. at par with Robert Gentleman/Ross Ihaka and Guido van Rossum. Keep it up 👍
The tutorial is clear and VOSviewer is a very nice software. A lot of thanks to you and your colleague.
Works really well...been working on "work motivation" .the extracted clusters support the extant literature...specific associations between major theories is particularly insightful... thanks a lot!
Fantastic video! It helps a lot to know how it works. Thank you!
Thank you for your contribution. Amazing product. Thanks again.
Brilliant! Thanks for the splendid work!
Can we also create network based on co-occurrence of words in abstract, results, discussion as well ? particular when we have downloaded all full articles and storied in zotero ?
Thank you so much. But, I need more detail about VOSviewer analysis.
Thanks and congrats for this video.. This is help me a lot... Have a good week..
Thank you.
Huge respects for you
Wish the video was longer and explains contents in details
bedankt! superb cool apps for researchers.
Does anyone know how to format cvs file so it will be accepted by VosViewer? It is not taking my csv file and my Excel does not offer csv.MS-DOS. Thank you!
I have to use data of Scopus and WOS both for Bib analysis using VOSviewer. Can you post the link of a video how to check overlapping/cross checking to avoid repetition in the references?
Thank you for sharing this presentation. Please I need a guide on how to change the first letter of the keywords to upper case. Thank you
in advance
Very helpful manual! Thank you
Hi Nees, could you explain what are the differences among co-authorship, co-occurrence, bibliographic coupling, and co-citation in "type of analysis", if I all select "unit of analysis" as "authors"? Thank you!🥺🙏🙏
Apr-2023: In the manual for VOSViewer v1.6.19 (Topic: 2. Terminology, Page 6/54), I see ".. The strength of a link may for example indicate the number of cited references two publications have in common (in the case of bibliographic coupling links), the number of publications two researchers have co-authored (in the case of co-authorship links), or the number of publications in which two terms occur together (in the case of co-occurrence links)...".
From this I infer that "co-occurrence" refers to "terms" (keywords).
how do you know what the clusters/colors signify? I don't see any labeling. Do you need to infer this from the results?
Excuse me, I have a problem in the total link strength column, I get 0, what could be the reason for that?
Is Web of science no longer working?
Is it possible to merge the database from Web of Science and Scopus, excluding the duplicates and importing to VOSviewer?
Can we generate network that contains only one word. for example, i want to generate the connection between one word to another word in dataset i.e. tweet. Thank you
Thanks for your contribution!
please can you give a step by step way of using this software to write a paper from the scratch. If you can also take into consideration people that do not have access to Scopus and other platforms.
One question is how to extract all clusters after co citation documents. Tks a lot.
This is amazingly insightful! Thank you so much for taking your time to contribute on how to use this exciting tool!. A question from my side is - in the case of interdisciplinary research where the literature is randomly distributed and won't all be in 'Web of Science', how do I make use of Vos then? Like is there a manual way to input the different papers I have selected as my research sample then since your video assumes that all the papers one would have used are also appearing in web of science. Hope this make sense..
In addition to Web of Science, VOSviewer supports a number of other data sources, including OpenAlex. Compared to Web of Science, OpenAlex has the benefit that its data is fully open and that it offers a broader coverage of the scholarly literature.
Hello Sir. I tried to install and run VOSviewer after installing Java. However, VOSviewer is not running post several attempts. It always says that Java Virtual Machine could not be created. Could you please provide any solution so that I can follow and try again? Thanks in advance.
Really nice, thanks a lot!
Hi Nees, could you please advise how to deal when I have a term in several options (sgd, SDGs, sustainable development goal). I tried to change .txt file but it doesn't work.
Merging terms can be done by creating a thesaurus file and by providing this file as input to VOSviewer. Please see the VOSviewer manual for more information about thesaurus files.
@@neesjanvaneck Yes, I did but it doesn't work. I created thesaurus file in the Label column I indicated all variations and replace by column indicated alternative label. I saved as thesaurus_terms and uploaded with data-file. Finally I get a map with variations. Still trying :(
@@socialentrepreneurshipKG Could you send me your VOSviewer thesaurus file and the file containing the bibliographic data that you want to visualize? I will then try to take a look at your problem.
@@neesjanvaneck It works properly, Thanks a lot I found the video where they show how to upload a thesaurus file. Thanks a lot for Vosviewer; it helped me a lot. I wish you and your team success!
@@neesjanvaneck can we visualize by uploading articles in pdf form?
Will you Please help me? I need some clarification regarding science mapping with vosviewer
Dear Need Jan Van Eck,
I've tried to map papers according to their co-citations, and end up with a map similar to the one in your video. However, I also have 4 colors and can't understand the cluster behind it: I've looked into the manual and couldn't find anything. Could you please help me understand this?
Best,
Michaël
It ‘S good to know this software. One more question is that do they have co citation?
As a novice I want to ask how do I create files that it acceps as Input?
nice video, could you please give me further information about keywords plus (co-occurences)? thank you in advance
I am getting anonymous as author with maximum citations,how to get the author name in citespace?
Hi! Does it work for Two-mode Networks? Thanks!
thanks for this tool!
thank you so much
Thanks you sir
Thank You
My vosviewer doesn't have too many option.
sir, i am trying to upload pdf formats but unable to work on ..kindly help
How can we search a topic in vos viewer?
Hi Nees Jan van Eckm, can we use Vosviewer to select suitable journal for any article?
Yes, you can. This link will be helpful to you with regards to this.
Sir, will it help for pubmed Data?
How would I generate a graph of a journal article and all of its citations? Can this be done directly from a PDF and/or using Zotero?
Ah, seems like I want www.citnetexplorer.nl/
I can not find the site on minute 5.2. Please tell me please the link
www.webofscience.com
please can you do this base on a real geographical map?
Can you update the tutorial video to version 1.6.4? :)
Sir, can we use excel file in VOSviewer? If yes, how?
I try to do the same but not working
Did you manage that?
now, this softwere can't download!
Como puedo cambiar el idioma a español???
No tiene versión en español
congrats!!!
Hi Nees, can the software get corrupted? The latest version I downloaded is constantly showing errors and many of its functions are also not working.
I have not heard of other users having this problem. Perhaps you could send me a DM.
Thanks
Amazing
I am using file from scopus database but i just only visualize about author and their co-citation other options are disabled.How i can solve this?

me too how can I solve this issue?
CAN SOMEONE EXPLAIN THIS TO ME?
