There are two kinds of papers included in EI, one is periodical papers, which can check the impact factors of periodicals, and the other is conference papers, which cannot check the impact factors. In addition, the impact factor is aimed at journals, not articles. There is no such thing as an impact factor in an article. It is much more difficult to recruit EI periodicals now. If your organization recognizes the conference papers, I suggest you send them. You can download it from EI Academic Conference Center. There are many learning materials in this field. Learn by yourself.
