Aside from Beall's List of Predatory Journals and Publishers, are there other lists of the same content? For example, World Scientific Publishing Company is not on the list of Beall, but how to know if this publisher is predatory?
I recommend to look into some of Rob Keller 's answers (https://www.researchgate.net/profile/Rob-Keller/answers) concerning the quality of journals, e.g. Oct 28: "Medical Research Archives - predatory???" and Oct 16: "Is Optik a good journal?" You will see how to distinguish a journal of good quality from a predatory journal.
I have written a paper, viz. “Writing for Publication for Students and University Staff”, which discusses how to identify predatory journals. The paper is freely available on ResearchGate: https://www.researchgate.net/publication/342549330_Writing_for_Publication_for_Students_and_University_Staff.
Dear Ma.Kresna Navarro In addition to the replies of Wolfgang R. Dick and Rodney Duffett which might help you to answer your question in general, I can say that the particular publisher (https://www.worldscientific.com ) you mentioned is discussed here on RG already: https://www.researchgate.net/post/Is_World_Scientific_Publishing_a_reputed_and_reliable_one
Not being included in the Beall's list can be a reassuring sign and in the given link you can find some of the arguments why this particular publisher is not predatory.
