Altmetrics Definition
Altmetrics, or alternative metrics is a catch all term which refers to the statistical analysis of alternative forms of capture of research articles and research products such as presentations and conference proceedings. In other words, alt-metrics is all of the other ways of capturing and measuring how people use research output. Examples are twitter mentions, download counts, and comments on your work. Such metrics are imprecise, but they do capture the ways in which your and other scholars work is being used. Altmetricians look at work on the article level rather than at the journal or research field level, thus their work tells stories about an individual researcher rather than a body of researchers like bibliometrics does.
