The primary metric for measuring the performance of scholarly journals is currently the Impact Factor. We calculate the Impact Factor based on the standard method of calculating the citations of papers published in the journal during the two preceding years.
For the sake of consistency, we use CrossRef as the standard for identifying citable documents. The results are very similar to the SCI Impact Factors. Still, there are a few journals, such as Nature and Science, whose Impact Factors are lower than those reported by Clarivate because CrossRef makes more documents as citable documents.
Contrary to the SCI Impact Factor, which is released on specific dates every year, we regularly update the Impact Factors published on the website. There will be no significant changes, but as we frequently parse the references, we may discover citations that have been missed or correct wrongly identified citations.
We are also working on various metrics developed in the realm of scientometrics. However, all metrics are helpful for the sake of comparison, and their usefulness depends on the understanding of users. Otherwise, they are mere numbers. To avoid providing loads of information, which might be useless to most users and just adds to the complication, we are exploring practical metrics, which can assist the researchers in judging the media of scientific publications.
