ABSTRACT

ABSTRACT Traditional research evaluation relies heavily on external indicators such as citations and social media mentions. This study proposes an alternative approach by evaluating the impact of researchers through their research content, introducing internal evaluation indicators. Three author-level topic-based evaluation indicators were established to evaluate researchers’ innovative impact, using the topic model BERTopic, the Jensen-Shannon divergence and interdisciplinary measurement. Based on these indicators, a multidimensional evaluation framework that systematically integrates innovative impact with established academic and social impact dimensions was constructed. An empirical analysis of researchers in the fields of scientometrics and informetrics reveals two key findings. First, researchers’ innovative impact can be assessed by quantifying research topics in terms of novelty, interdisciplinarity and relevance. Second, innovative impact can be used as a complementary evaluation dimension to traditional academic impact metrics. This study enriches research evaluation by introducing internal research content-based indicators, expanding the dimensions of academic impact, and providing new methods and ideas for research evaluation.
