and article reference managers such as Mendeley are now being used to communicate and discuss research. Alternative metrics ('altmetrics'), first described by Priem and colleagues,

Digital scholarship and the relocation of research dissemination from paper to the web has led to a growing body of conversation about research taking place online in a range of non-traditional sources. The momentum of the alternative metrics or ‘altmetrics’ movement – tracking attention to research papers across sources such as policy documents, news sources, blogs and social media – signals a...

This paper presents a review of altmetrics or alternative metrics. This concept is defined as the creation and study of new indicators for analysing scientific and academic research activity based on Web 2.0. The underlying premise is that variables such as mentions in blogs, number of tweets or saves of an article by researchers in reference management systems, may be a valid measure of the us...

In this study, we investigated the impact of scientific publications of the Italian SIMPAR (Study In Multidisciplinary PAin Research) group by using altmetrics, defined as nontraditional metrics constituting an alternative to more traditional citation-impact metrics, such as impact factor and H-index. By correlating traditional and alternative metrics, we attempted to verify whether publication...

Emerging metrics based on article-level does not exclude traditional metrics based on citations to the journal, but complements them. Both can be employed in conjunction to offer a richer picture of an article use from immediate to long terms. Article-level metrics (ALM) is the result of the aggregation of different data sources and the collection of content from multiple social network service...

More evidence of the meaning and validity of ALMs and altmetrics, coupled with greater consistency and transparency in their presentation, would enable research funders to explore their potential value and identify appropriate use cases.
