Altmetrics: Alternative metrics of scientific impact based on social media

Abstract

Alternative metrics or “altmetrics” can be defined as the study and use of academic impact measures based on the activity of online tools and environments. Altmetrics aim to measure the different forms and patterns of meaning and use of scientific products, looking not only for publishing in traditional media, but also the broader process of dissemination in emerging environments. Its goal is to update the scientific concept of influence in a century characterized by the rapid spread of information and adoption of social media on a global scale. This paper presents the altmetrics and analyses its application to assess academic impact.
