How to find if a paper is in top 10% most cited articles in a journal? 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?
Go to Web of Knowledge and search by publication name. Then sort by citation count and find the 10% cutoff (e.g. if there have been 10,000 papers published in that journal, then the article with the 1000th highest citation count is the 10% cutoff). Then find the paper you're interested in, and see if it's above or below that 10% cutoff.
