MyRI: Measuring your Research Impact is an online tutorial developed by a collaboration between University College Dublin, Dublin City University, Technological University of Dublin and Maynooth University.
While research outputs can take many and diverse forms, the most commonly recognised type is publication. The impact of a publication can be measured qualitatively through peer-review and quantitatively through various metrics. The quantitative measurement of publications is generally referred to as bibliometrics.
