Benyou? References. If you copy a passage from another work, the short one should be quoted, followed by a quotation, and the long one can be indented and followed by a quotation. If you borrow a word, if it is key and involves the core idea, you'd better add a quote. Summarize other works or explain their theories in your own words, without quotation marks, but also with reference. I'm not sure. It's better to add than not to add. Anyway, there are not many references. Whether a paper can be published in IEEE depends mainly on academic integrity. I hope I can help you.
