One may specify some keywords in one's Google Scholar profile, e.g.:
How can I see the number of Google Scholar profiles that have a given keyword? E.g., the number of Google Scholar profiles that have a given keyword "computer vision" or "natural language processing".
I think it's possible.
You'll find this python code very handy for this challenge: https://github.com/WittmannF/sort-google-scholar
You will be able to identify keywords, and rank your results (e.g. by citations/year).
If the Captcha process gets in the way, use this workaround: https://medium.com/analytics-vidhya/how-to-easily-bypass-recaptchav2-with-selenium-7f7a9a44fa9e
Good luck.
One cannot see the number of Google Scholar profiles that have a given keyword, unless willing to click on the > button to go to the next 10 profile links for as many times as need to reach the last page (> 1000 times). One may encounter some human verification box from Google as well on the way.
