I saw in some applications that some researchers state that their papers are in top 10% most cited articles, but they never state how they calculated this. I have tried Web of Knowledge and there are some metrics there, but the don't really match the text from those applications. For instance, I found this kind of formulation in one of the applications:
For the articles published Engineering category in 2015, the average number of citations is only 1.22. This article is therefore one of the top 10.00% most cited articles published in Engineering in 2015.
I saw that it was calculated using Google Scholar, but I don't know how they do it. Can anyone please help me to understand how can you see if you paper is in top xxx% most cited articles like in the text above? Is there a software for that? Or is there any relation with the h-index that can give that for a certain year?
