Altmetrics is a generic term formed from the contraction of alternative and metrics. It refers to non-traditional academic performance metrics drawn from online sources such as social media. The employment of altmetrics has significantly increased since they were first proposed in 2011. They are still controversial and there is no consensus about their value. Most research points to their usefulness as early predictors of academic citation and as tools to measure networks and societal impact of research.
In this project I would like to contribute to this discussion with a multilevel model to measure how well altmetrics signal scholarly impact, measured for example through peer-review assessments or the number of citations after a given period of time. A multilevel model is a statistical model that allows for heterogeneous impacts for units belonging to different categories, such as particular academic fields or time periods. The aim is to provide the first comprehensive analysis of the heterogeneity of the performance of altmetrics for different academic fields.
