( Watch a brief overview about PlumX Metrics.) The Five Categories:

We categorize metrics into 5 separate categories: Citations, Usage, Captures, Mentions, and Social Media. PlumX gathers and brings together appropriate research metrics for all types of scholarly research output. Collectively known as PlumX Metrics, these metrics are divided into five categories to help make sense of the huge amounts of data involved and to enable analysis by comparing like with like. Examples include, when research is mentioned in the news or is tweeted about.

PlumX Metrics provide insights into the ways people interact with individual pieces of research output (articles, conference proceedings, book chapters, and many more) in the online environment.
