I submitted a research paper to one of the Elsevier journals and got a response from the editor as below:
"The paper has got 23 % similarity in total and from one single paper 10 %. However, if you decide to address the aspects by me, then please develop and submit a new paper to me via the EES system, with a cover letter indicating how you have improved your document"
I checked for plagiarism with the help of Grammarly software and found total 4% similarity with one of my previous papers. That similarity was in two sections (i) where we describe the method and procedure of various tests that we carried out, which can be rephrased only a limited number of times as the settings/steps will stay the same. (ii) References/Bibliograghy at the end of the manuscript, which i don't know what to do with that as we can't rephrase references. Anyway i rephrased (i) which brought down the similarity/plagiarism to 2% and this 2% was lying in References/Bibliography. After rechecking i prepared a cover letter as per the editor's comment explaining all this and resubmitted my paper. Next day i got exactly the response from that editor, not even a character or word different.
"The paper has got 23 % similarity in total and from one single paper 10 %"
Don't understand one thing is there a difference in similarity check with different softwares? Or does the software that these publishers use show exaggerated results?
Secondly, if there is a similarity in writing the setup/procedure of a particular test, how to deal with it. You can rephrase it only a limited number of times?
Thirdly, what to do with the similarity in referencing/bibliography at the end, does the publishers/editors expect us to always look for a different reference or they want us to rephrase even the reference/bibliography?
