External expert identification and mapping through author publication altmetrics and network analysis

Challenge: how to identify influential external experts through an analysis of publications activity.

Our approach: we investigated combining multiple article-level metrics (i.e. ‘altmetrics’) with an author network analysis to identify experts who contributed to highly impactful research and were well connected with

other experts in their field.

What we did: analysed a sample of publications on a selected topic that had high altmetrics impact to investigate the utility of this approach.
