We measure the impact of “altmetrics” field by deploying altmetrics indicators using the data from Google Scholar, Twitter, Mendeley, Facebook, Google-plus, CiteULike, Blogs and Wiki during 2010- 2014. To capture the social impact of scientific publications, we propose an index called alt-index, analogues to h-index. Across the deployed indices, our results have shown the high correlation among the indicators that capture social impact. While we observe medium Pearson’s correlation (ρ= .247) among the alt-index and h-index, a relatively high correlation is observed between absolute social citations and absolute scholarly citations (ρ= .646) – also with their natural logs we report positive correlation (ρ = .517). Interestingly, we find high turnover ofsocial citations in the field compared with the traditional scholarly citations, i.e. social citations are 42.2% more than traditional citations. The social mediums such as Twitter and Mendeley appear to be the most effective channels of social impact followed by Facebook and Googleplus.Overall, altmetrics appears to be working well in the field of “altmetrics”.
