Thank you for all the answers. In my defence, Farid, I am not a computer scientist! :) . The question is that I have been invited to the editorial board of these publications and wanted to know if they had any credibility. Thomson reuters only gives us ISI Journal but journal that are in the first year have no ISI.
I advise against being part of the editorial board of any journal from those publishers. It may damage your reputation, and concerning your country, I have doubts it is relevant to your CV.
