Today, the publication of a researcher’s articles in quality journals testifies to his/her recognition by the academic community. Therefore, each researcher tries to publish articles in the journals indexed in the academic databases. Currently, when the number of scientific journals grows at high speed, the choice of a reliable publisher and publication of articles in a quality journal by the researcher is one of the most important problems. Today, there are serious requirements for the publication of scientific articles in the influential journals. And this increases the number of fake, hijacked, predatory journals and publications. As in some foreign countries, one of the main problems faced by scientific researchers in Azerbaijan is the threat of pseudo-journals. Research organizations and universities also try not to fall into the trap of such journals and publishers. This article provides extensive information about the characteristics of "predatory" journals and publishers, and provides examples. It also analyzes hijacked journals and misleading metrics. To avoid such unpleasant situations, the concept of an “anti-predatory” system, which automatically identifies “predatory” journals, is based on the international experience, and a simple expression of this “anti-predatory” system is presented in block schemes. The proposed system can be applied in research organizations and universities, etc. for the definition of quality or predatory journal (pp.96-102).
