Thank you for the video; it was very helpful. However, after following your steps, I encountered an issue. My Zotero library contains 200 articles, but when I exported it to a RIS file, the file size was only around 231 KB, and when I uploaded to Vosviewer with the minimum number of occurrences of a keyword (1), it only selected 5 keywords out of all of these articles. Can you help? I checked the article; they are all saved from the web.
By using narrowing down with Zotero, Since this data is based from multiple databases; how we can map that a certain data is availble only on a specfic database.
Thank you for your great video. Really helpful. However, I have a problem with the RIS file from zotero (articles and book chapters added via doi to zotero). I followed all steps of your procedure, I added the file to vosviewer, and the only option I got is to analyse co-authors without the possibility of selecting co-occurrence. Happened multiple times. Even after creating groups and libraries from scratch. Has this occurred to you and do you know what might be the problem? Thank you!
Thank you, I would be grateful if help me to solve this problem. I followed the steps but in the last step there is an error. ERROR WHILE READING RIS FILE, CAN NOT FIND AUTHOR (AU/A1) OR KEYWORDS.
Thanks for your question! I have been messing around with VOSviewer and I think the best way would be to download the full citation data from Scopus (which is csv) and then download the same data from WebofScience in Excel. The tricky part is that the order of the columns is not the same so you would then re-order the columns of the WebofScience sheet to match the Scopus sheet and then copy the data to the Scopus file. From there you should be able to import into Vosviewer through the normal Scopus file upload which gives more options for co-citation and country collaboration analysis. I haven't tried actually executing it yet but this is my thought process. Once I sit down to do it if I have any other suggestions I will let you know. If you find a better way to do it please let me know! In case it is helpful I did record a basic collaboration of countries visualization in VOSviewer here: ua-cam.com/video/4GEUne3_jm0/v-deo.html And another one of country visualizations that may be easier than creating the combined record of all of the elements of a Scopus record: ua-cam.com/video/JGFjZNfeDnE/v-deo.html

Thank you so much. You have already helped me. However, I want to ask "Can we do Bibliographic Coupling and Co-citations Analysis with a merged file (Scopus and WOS) such as RIS?" Because I cannot see the option while I upload RIS, also the same in the video as it only shows co-authorship and co-occurance.
Hey Anwar, great question! So far I have not been able to find a way to do those analyses with a merged file. I will mess around some more and if I find a way I will let you know!
@@nguyenthuylinh2382 Anwar and I have been working on it but I am waiting from a reply from an author who has done it before. I will let you know as soon as I do!
@@nguyenthuylinh2382 Good, Authorship and Co-occurrence is possible in VOSviewer on a merged data set. I have tried on a merged RIS file. However, Co-citation and Coupling are not possible through RIS. So I practice Scimat and found it interesting for a merged file. Let me know if you have another question.
@Gabriela Nagle Alverio is really helpful and perhaps she will find a solution for it. Btw, there is a paper which explains the procedure of formating merged file for VOSviewer but I could catch the way. Echchakoui, S. (2020). Why and how to merge Scopus and Web of Science during bibliometric analysis: the case of sales force literature from 1912 to 2019. Journal of Marketing Analytics, 8(3), 165-184.
Hi, thank you for sharing this tutorial. But I have encounter a problem when using the RIS file in VOSviewer. When I tried to impost the RIS file into VOS, it says "incorrect use of quotes" and cannot proceed to further steps, is there any solutions to this problem? Much thanks.
Hey Peishen, I'm not entirely sure why that's happening although what I would try to do is download it in a different format and import it based on the default format for that database. For instance, Scopus uses CSV so maybe trying that will help.
@@gabrielanaglealverio8430 Thank you so much for your presentation. When I try to RIS file to analysis sth wrong. In Create Map window (Choose type of analysis and counting method), It does not permit choosing Co-occurrence. Can you help me? Thank you!
@@meoconkocao Hey Dung, hmmm my guess would be that there is something about the file format that is causing VOSviewer not to read it. Can you try downloading in different formats?
Thank you very much for the video, very helpful. Can you please help me: I have data of Scopus (BibTeX) and WOS (plain text). However, when I upload to Zatero, the WOS file uploads only 10 papers while it has more than 800 papers. However, Scopus works well. I do not have RIS file of WOB, is there any way to solve the issue or I should find RIS for WOS data? (I don't have access to WOS now).
Hey Anwar, great question. As far as I know plain text does not transfer well to Zotero. If you have the search string and want to send it to me I can send it to you in BibTex or RIS format if you want. My email is gabriela.nagle@duke.edu!
Estimada Gabriela. Gracias por tus aportes. Sin embargo le pregunto: ¿Es posible mapear y analizar simultáneamente con VOSviewer datas de Google Scholar, WOS y Scopus?? Es decir, procesar y lograr reflejar en 1 mapa-análisis datos de los tres archivos y bases
Gracias por su pregunta! Por lo que yo sepa, no es posible utilizar datas de Google porque no se pueden descargar en una forma que VOSviewer sepa leer bien. Lo mejor sería usar más bases de data como WOS y Scopus para incluir más papeles
@@gabrielanaglealverio8430 Hola. Muchas gracias estimada Gabriela. Tiene usted razón, sin embargo, en tal caso quedarían excluidos del análisis muchos trabajos que se han publicado en Latíndex y SciELo, por ejemplo. He pensado y estoy indagando si hay otro programa o software que no sea VOSviewer que pueda emplearse, o si seria aceptable aplicar distintos, cosa que de pronto no me parece coherente o aceptable. Si puede sugerirme algo al respecto se lo agradecería. Mil gracias anticipadas. Saludos
hello Gabriella, thank you for the video. is there an email id I can connect with u on? need help with a paper I'm writing. any assistance would be appreciated. thanks
Thank you, this was incredibly helpful. I couldn't find any content like this anyplace, so please keep making these kinds of videos.
This was very helpful, thank you! Please keep creating these types of videos, couldn’t find this content anywhere.
Thanks so much for watching! If you have any requests let me know!
Really useful, super easy to follow! Thanks for uploading!
best video available for combining data and eliminating duplicates, thanku so much
Great stuff, thanks! :)
VOSviewer only analyze abstracts, authors, dates and such? I would like it to analyze all the content from PDF documents.
Thank you, I really needed this. Came across your video just in time.
Good I'm so glad it was helpful!!
Love you too, beside the way you describe keep growing and sharing great things 💗
Your video has been extremely helpful! Thank you!
Thank you! Just wondering what can be done if there is a bilingual corpus?
Great tutorial Gabriela - thanks a lot for taking the time to upload this!

it was really helpfull, but i am not getting the co-occurrence in the options. plz suggest

Hello Gabriela, is there any published paper with this methodology?
thank you so much, you are an angel
Thanks for this I am using mendelly , how can I do this
do you why I can't I use the exported csv or bibtex files in rstudio or biblioshiny?
Mam what if i have a csv already of merge databases but it does not work well in VOS. please help. Is it possible without zotera?
thank you! very interesting video!
Thank you so much. 🙏
