I am trying to use VOSviewer for analysis. I’ve come across with some difficulties when creating a map for bibliographic data. A set of keywords taken from Web of Science were added to the process. Because of being singular & plural, the keywords do not give the expected quantitative value for me. For example, cities & city were taken into two categories and because of that, the results do not give the expected value. Is there any method to edit them in the verification table or anywhere before going to the map?
Ask the developers at http://www.vosviewer.com/contact
I have asked them questions about it when reviewing research which used it. They are always quick to reply and happy to help.
Thank you Brandt Dainow for your support. I already asked them & not received an answer yet. May be I'll try again.

Hello Ingrid,
I found a way to use Thesaurus and it worked. Thank you.
I searched for this issue and found this post. I just found the instruction in the VOSviewer manual. I could merge-common keywords successfully now.
My procedure was
1) try to run the first analysis to get the list of keywords
2) save the node file as a txt file
3) create a new excel file with 2 columns: label and Replace by
4) Import the keywords list from 2) and start sorting
5) Run again, this time choose Thesaurus file with your file from 4)
Best,
Kulacha
