A proposed framework to address metric inflation in research publications.

Background: Since the advent of online research metrics, which began with Web of Science in 1997, these metrics have been increasingly used to rank researchers and universities. Over the last two decades, the easy access to research metrics has greatly benefitted the academic community and beyond by providing quantitative measures for ranking researchers, universities and departments. However, this accessibility, accompanied by a tendency to quantitatively evaluate research quality and impact, has also shifted the focus toward practices aimed at enhancing research metrics rather than pursuing high-quality, potentially path-breaking research.
