Does high-impact research come at the expense of quality? An automated analysis of the REF impact landscape

As part of the 2014 Research Excellence Framework, the impact of research was assessed for the first time. But how effective was the impact category in capturing the many diverse forms of interaction between academia and society? Were certain interpretations of impact more highly rewarded than others? And does high-impact research come at the expense of quality? Martin Zaltz Austwick and his research team used a text mining technique to analyse impact case study submissions and address some of these questions.
